MBR (Master Boot Record) partitioning scheme is the most common scheme used in Windows computer systems. This scheme allows at most four primary partitions, one of which can be the extended partition. These primary partitions are defined by corresponding 16-byte entries that form the partition table, which is included in MBR of the hard disk. As the standard rule, the MBR can contain only one extended partiton and each boot record of extended partition (EPBR) can consist of only one link to another EPBR. If this rule is violated somehow, you may experience several issues using utilities that directly interact with the partition table, such as a partition manager. In such cases, you need to repartition the hard drive and restore from the last backup. If not available, you require a Data Recovery utility.

The following scenario illustrates a similar type of problem that can occur when suggested type of partitioning is not followed. You observe some partition issues on a Windows based computer. As a result, you use a third-party disk partition manager but the tool fails to perform the specific task. Additionally, you receive an error such as mentioned below:

“Init failed: Error 100 Partition table is bad”

The tool cannot proceed further after you receive this error message.

Cause

The error occurs when the partition manager cannot recognize the hard disk partitions. This specifically occurs when the partition table doesn't obey the standard rule of disk partitioning (as specified above). The same issue can also occur if the hard disk contains more than one active partitions.

Solution

To solve the above error, you need to follow the below steps:

Delete all the existing hard disk partitions Recreate the partitions Restore the deleted data from the last backup

There can be situations when the backup might fail or contain incomplete information. To deal with such problems, you are suggested to use a Partition Recovery Software that might recover the lost data from the corrupted, deleted and formatted hard disk partitions. The Windows Data Recovery utilities use specific scanning algorithms to examine the logically crashed drives and recover the lost data safely and easily.

FAT (File Allocation Table) is one of the most widely used file systems used now-a-days with various versions of Windows operating systems
and memory cards. Every logical partition contains a FAT that consists of file allocation information and the information of free allocation units that need to be assigned to files. Although the FAT file system is reliable, corruption still occurs due to various reasons. In such situations of FAT corruption, your system becomes unbootable, resulting into inaccessibility of data saved in FAT based hard drive. To access the data after FAT file system damage, an easy way is to restore the data from an updated backup. But, with inaccessibility of data backup or backup falling short to restore the required data, an ideal option left is to use an advanced FAT Data Recovery application that can recover the lost data.

To illustrate the above scenario, consider a practical case the below error message pops up when you attempt to boot your system:

“No Bootable Media”

As the above error message appears at the time of booting the system, you wont be able to access the data saved in the hard drive.

Cause:

The above error message because the FAT file system has been corrupted. Few main causes for file system damage are improper system shutdown, human errors, and virus attack.

Resolution:

To isolate the above error message and to access the data after the above error message appears, you will need to follow the below steps:

Run CHKDSK utility to repair the FAT file system. If the problem persists, format the hard drive.

While the latter resolution resolves the above error message completely, it also deletes the data saved on your hard drive. In such cases, if the backup is not available, then you can only recover your formatted data by using an advanced third-party FAT Data Recovery software.

A FAT Partition Recovery utility thoroughly scans a FAT based hard drive and recovers almost all data, even after formatting. The data recovery utility can be downloaded from the Internet.

Stellar Phoenix Windows Data Recovery is an efficient FAT Partition Recovery tool
that recover lost, deleted, and formatted data from both FAT (FAT12, FAT16, FAT32, VFAT) and NTFS (NTFS, and NTFS5 ) based hard drives. The detailed help manual attached with the tool allows even a new user to perform recovery easily without any technical knowledge. It supports Windows 7, Vista, XP, 2003, and 2000.

Windows is considered to be a reliable and efficient operating system, but as bugs cannot be always resolved out, a Windows user can observe several types of issues. These issues can be critical enough that might compel you to reinstall Windows and/or reformat the existing partitions. In such situations, restoring from data backup becomes an inescapable option. If this is not possible, the last resolution is to use a Windows Data Recovery utility. The further reading discusses one such problem, in which a user might repeatedly get error 0x800703ED while normal operations with the computer.

The general symptoms that occur in conjunction with error code '0x800703ED' are:

Sluggish computer performance Frequent hangs up when running an application Installation issues Problems when starting or shutting down the computer Computer freezes

The Windows based computer shows the above stated behavior when the Windows registry is corrupted. Windows registry is a system-specified database that consists all configurations for Windows and the installed applications.

Error 0x800703ED can also be related to volume corruption. In such cases, you may encounter errors such as

“The volume does not contain a recognized file system.”

This error indicates that the computer cannot recognize the file system of the partition and hence declares it corrupted. It can also occur if all the required file system drivers are not loaded.

Solution

To solve Error 0x800703ED in Windows, you need to apply solutions such as:

To correct Windows registry issues, it is recommended to reinstall Windows and restore from backup. This will refresh all the registry files. In case of volume corruption, you should run chkdsk. If this doesn't help, recreate the corrupted partition and restore from the last available backup.

In case when there is no suitable backup present, you are suggested to use a Windows Partition Recovery utility. These scanning based products can run exclusive algorithms to locate and recover the lost data from a logically crashed drive. The Windows Data Recovery tools are easy to use because of their interactive user interface.

Master Boot Record (MBR) is primarily used to hold disk's primary partition table, identify particular disk media, and bootstrapping operating systems. The first sector of the hard drive is located at the Main Boot Record area and consists of entries for primary partition in the partition table. Corruption in MBR can be caused due to numerous logical reasons, like improper system shutdown, operating system malfunction, malicious software like virus, and human errors. MBR once corrupted, halts the booting process of Windows, resulting in inaccessibility of data stored on the hard drive. An appropriate way to access the lost hard drive data is by restoration of data from an updated backup. However, in worst case scenarios, where you have not created any backup, a powerful third-party Data Recovery application acts as a boon.

To illustrate the above case, consider a scenario where you encounter any of the underneath error messages when you attempt to boot
your system:

“Input/Output Error” Or “Operating System not found”

Occurrence of any of the above error messages results in inaccessibility of hard drive data.

Cause:

MBR corruption/damage.

Resolution:

To resolve MBR corruption and to access the hard drive data, you will need to follow the below steps:

1.Insert Windows 7 installation CD and select your default 'time','date', and 'language'. Click Next. 2.Click 'Repair Your Computer' option for opening System Recovery window. 3.Go to command prompt and run 'bootsect.exe' utility. 4.Run 'bootsect /nt60 C:\' (in case Windows 7 is installed in C partition). 5.Eject the CD and restart your system.

While the aforementioned steps resolve MBR corruption in most cases, there are some cases where the above steps fail to do so. In such cases, the hard drive data remains inaccessible as any of the error messages pop up while booting your system. To resolve the error messages, it is advisable to format the hard drive partition. Although formatting resolves both the error messages and MBR corruption, it also deletes the data saved on the hard drive partition. In such cases, the formatted data can be recovered by using advanced Data Recovery Software. A Data Recovery
utility salvages the hard drive and recoups the formatted data by using advanced scanning methods.

Stellar Phoenix Windows Data Recovery is a partition recovery software that ensures complete recovery of data from a formatted hard drive. The Data Recovery product supports almost all file systems like FAT12, FAT16, FAT32, VFAT, NTFS, and NTFS5 file systems. It is compatible with Windows 7, Vista, XP, 2003, and 2000 operating systems.

In spite of your best attempts, your system may get infected by a virus or some other malicious programs. Viruses need to be gotten rid of, to restore the system to its previous working state. Removing the virus from the system may be quite simple, or even amazingly difficult, depending upon the methods deployed to remove them. You may also come across data loss when your system gets affected by a virus. Data loss may be permanent or reversible. Mostly, Data Recovery Software can help recover all your lost data.

Most of the virus scanners use virus definition files to scan the system for viruses and deploy several algorithms for removing different types of viruses, and fix all the damage caused by them. However, in some cases, though the anti-virus detects the virus, it can not remove the virus from the system. In such situations, the system remains affected and is prone to many critical problems.

One should bear in mind that there is a possibility of false positive, i.e., the anti-virus application may identify a normal file as a virus, even though it may not be so. Always make sure that the file that has been marked by the virus scanner, as a virus, is actually so, before trying to remove it, or you make the situation more critical.

When a virus infects the boot sector of your system, it can be removed simply by rewriting the boot sector code, which resides on the hard drive. This can be done manually, by anyone. To do this, boot the system with a clean floppy and use “FDISK /MBR” command for rewriting boot sector code.

However, this solution is not ideal for all cases. Sometimes, viruses cause a lot of damage that has to be undone using a program created specifically to repair the damage done by the virus and can handle the situation properly. The “FDISK /MBR” command, though very useful, in most of the critical situations, can only wipe the virus, but not fix the damage done by the virus.

But, there are situations, where even these programs fail. In such situations, hard drive formatting is required to remove the virus. But, formatting removes all the data too. However, this is a trivial problem, and can be fixed using Data Recovery Software. These hard drive data recovery software extract lost data from all the sectors of the hard drive by perform in-depth scan of the affected hard drive. Any high-end data recovery tool comes equipped with simple and interactive user interface, which eases Data Recovery, and helps even first-time users to extract their data. A data extracting software, should be read-only and non-destructive in nature, as such a software would ensure integrity of the original data.

Stellar Information Systems Limited is the foremost provider of world-class recovery applications to deal with all types of logical data loss situations and recover partition. The recovery software are specialized and available for different operating systems including Windows, Mac OS X, UNIX, Linux, and Novell.

A Windows 7 based computer can become unbootable for several number of factors. One of the typical results of such problems is Blue Screen Of Deaths (BSODs) at startup, which generally render your data inaccessible. In such cases, the data backup availability is essential or otherwise, it can leave you in unavoidable situations of using a Windows Data Recovery utility.

For instance, consider you try to start a Windows 7 based computer system
. At this point, the system might fail to respond and prompt an error message as below:

“STATUS_SYSTEM_PROCESS_TERMINATED”

Or

“STOP: 0xC000021A”

The error might prevent you to let access the data stored on the hard drive.

Cause

The mentioned stop error occurs when a subsystem (such as Winlogon etc.) of user-mode in Windows 7 has been compromised. Windows 7 cannot guarantee the security. The error typically occurs when Windows 7 switches into kernel mode. The system cannot run without the aid of these services. This can occur because of some third-party tool.

One another possibility of this error to occur is that the system administrator has modified the permissions to access system files and folders and these files are no longer accessible.

Solution

You cannot use kernel debugger in this case because these issues occur in a user-mode process. To solve it, you should try these suggestions:

If you have updated any device driver, perform a driver rollback. Start the computer in safe mode and perform a 'System Restore' through command prompt If you are unable to boot the computer, boot it using Windows installation disc and restore it to the last working state using 'Last Known Good Configuration' option. If none of the above solutions work, reinstall Windows 7 provided a good backup is present.

In case you cannot access the data and data backup is not present, you are suggested to opt for a Windows Partition Recovery utility. These are suitable Windows Data Recovery applications built for scanning the logically crashed drive and recover the lost data safely. The software are easy to install and use.

Many of Windows 7 users might be unaware of the fact that when they install Windows 7, it forcefully creates a separate 200 MB partition to store WinRE (Windows Recovery Environment) files. The partition is hidden, automatically activated, is not labeled by any drive letter, and has only 32 MB of space occupied. Though the partition is required to hold system and bootable files to aid in recovery after crash, but cannot be deleted using normal tools like Windows Disk Management. Also, this has been observed that when the user tries to delete it using a third-party partition manager or partition editor, the partition table might get corrupted or invalid. This causes other data partitions to become inaccessible and create critical data loss situations. To restore data in such scenarios, you need to either use the last available backup or apply a commercial Partition Recovery Software.

Consider a practical example illustrating such problems. You use Windows 7 DVD installation disc to an unpartitioned hard disk, a hard disk with unallocated space or a hard disk of which you have deleted all the existing partitions. You install Windows 7 and later, delete the 200 MB partition that is apparently taking unnecessary space to store WinRE files, using a third-party partition utility. After this, you observe symptoms like below:

Other hard disk partitions start behaving unexpectedly that suggests the corruption of partition table located in MBR (Master Boot Record). When you try to create a partition using the freed space, the partition utility shows a disk error.

Hard disk randomly shows unallocated disk space of 1 MB to 2 MB You cannot format the hard disk partition(s) Few or all hard disk partitions are lost

Cause

The 200 MB partition created by Windows 7 at the time of installation uses a non-standard partition type. So, when you use a partition editor or utility that does not recognize this partition type, it may result in partition table corruption.

Solution

To prevent such data loss from occurring, you should avoid installing Windows 7 on a non-partitioned hard disk or to unallocated disk space. Partition and format the hard disk before installing Windows 7.

However, to achieve lost Partition Recovery, you need a full backup. If not available or dirty, you are suggested to use a Data Recovery Software.

Stellar Phoenix Windows Data Recovery is a reliable and advanced application that recovers data
from corrupted, lost or inaccessible Windows partitions. The Partition Recovery utility is compatible with Windows 7, Vista, XP, 2003, and 2000. The tool features various qualities like 'Disk Cloning', 'Disk Imaging', 'Drive Status' that help getting suitable results.

Windows NT operating systems encounter various errors and issues, but the most problematic one is the STOP error message. These errors are commonly identified by an 8-digit hexadecimal code which may sometimes appear if the file, which is required at the time of system boot is corrupt or damaged. As a result, a STOP error occurs and the process of the system comes to a halt. Additionally, the hard drive data becomes inaccessible. An ideal way to overcome such situations is to restore the data from a valid backup file. However, if the backup fails or is not available, then you can rely upon a powerful Hard Drive Data Recovery application to recover your data.

Consider this example – Suppose, you start your Windows XP based system and suddenly the following STOP error message appears:

“Stop: 0xC000012F STATUS_INVALID_IMAGE_NOT_MZ

The specified image file did not have the correct format, it did not have an initial MZ.”

Along with this error message, you may also receive the following Trap Code:

“STOP 0x0000006b (0xc000012f, 0xxxxxxxxx, 0xxxxxxxxx,0xxxxxxxxx)”

After this error message pops up, the system stops booting and you cannot perform any other operation in the system.

Cause:

Most probable cause of the error message is:

The system was not able to load the files required for start up as the systems files used are corrupt. This may happen because of hardware malfunction while file copying was in progress. Thus, it is highly recommended to examine the system hardware thoroughly to determine the cause of the problem. This error message can also occur after installing new drivers in the system.

Resolution:

There is no particular file specified in the error message that might be causing the problem. So, you need to perform basic troubleshooting steps to solve the issue. Following are the troubleshooting steps:

Restart your system using Last Known Good Configuration option. Select the VGA mode option from the boot menu. This allows you to see the Windows XP system files on the screen and have a fair idea about the damaged or corrupted file. Use Emergency Repair Disk. This will replace the corrupted or missing driver file on the partition.

In majority of such cases, these measures help you solve the problem. However, if the problem does not seem to go even after usineasures, then you need to re-install Windows XP. A clean re-installation of the operating system results in deletion of all the hard drive data. In such situations, to recover your lost data, you will need to use a good quality Hard Drive Data Recovery application. These applications deploy intense scanning algorithms for Disk Recovery in all logical data loss scenarios.

Windows 7 Boot Configuration Data (BCD) store is a database that contains boot-time configuration data. This is a firmware-independent file and is a replacement of boot.ini file used in Windows operating systems earlier to Windows Vista. Once the file get corrupted, a Windows 7 computer loses the ability to boot. Since the file is editable through command-line tool called bcdedit.exe, you can use it to overcome the Windows boot issues. But if the corruption is high or the tool doesn't work, the last alternative is to restore from a backup and/or reinstall Windows. However, while backup is unavailable, you need a Windows Data Recovery solution to recover the lost data.

Consider a practical instance of such problems. You use a Windows 7 based computer and it fails to boot prompting an error that is similar to below:

Boot manager generic failure 0x000000e Repair Action: Boot configuration data store repair Result: Failed. Error code = 0x490

After this error message, you cannot access the data that is stored on the hard drive.

Cause

The boot information in Windows 7 BCD store is corrupt.

Solution

To solve the above discussed issue, you need to start Windows RE (Recovery Environment) in order to run Bootrec.exe tool as follows:

Insert Windows 7 installation disc in the drive to start your computer from it Press any key when prompted for Specify the language, currency, input method and other options Click 'Repair your Computer' and select the target operating system, click 'Next' Choose 'Command Prompt' under 'System Recovery Options' Type 'Bootrec.exe' and type ENTER

Once the tool is started, you can rebuild the BCD store using '/RebuildBcd' option. If this doesn't help, you can export the BCD using the following set of commands:

bcdedit /export C:\BCD_Backup c: cd boot attrib bcd -s -h -r ren c:\boot\bcd bcd.old bootrec /RebuildBcd

If the problem persists and your data remains inaccessible, restore it from backup or use a Windows Partition Recovery utility. Reinstall Windows if backup is available. A Windows Data Recovery can scan and recover the lost data safely without requiring any prior technical skills.

Windows system registry is the system-defined database that contains information like configuration files to store settings for user preferences, hardware, drivers, installed software and the like. With each modification in Windows computer, system registry is affected. It's something like the central control for the operating system and applications. Thus any impact on Windows Registry is reflected while the computer
functions. A corrupted registry can even make the computer unbootable and data inaccessible. At the critical stages when no valid backup is available and even Windows repair utilities fail, you might be compelled to use a Windows Data Recovery software.

The following illustration depicts a situation when a Windows system can fail to boot due to registry corruption. Consider you use a Windows Vista based computer and it becomes unresponsive for some reasons. You shutdown the computer forcefully, but the next time when you try to boot it, you receive an error message that reads as below:

File: \Windows\system32\config\system Status: 0xc000014c Info: Windows failed to load because the system registry file is missing, or corrupt.

The error also suggests to run repair using Windows installation disc.

Cause

Windows system registry file is corrupted due to unexpected shutdown.

Solution

You can proceed with the below steps to solve this problem:

Insert Windows installation disc and start your computer from it Press any key when prompted for At 'Install Windows' screen, select the language, time and currency, input method, and other preferences. Click 'Next' Click 'Repair your computer' and select the operating system you want to repair. Click 'Next' In the 'System Recovery Options', click 'Startup Repair' and/or 'System Restore' Restart your computer

If the repair ends successfully, the Windows Vista computer should boot now. If it doesn't, you need to reinstall Windows. However, it is recommended to reinstall only when you have a complete data backup. To extract the lost data, you either need to restore from backup or use a Windows Partition Recovery utility. A Windows Data Recovery software can scan the logically crashed drive and recover the lost data safely and easily.

Also known as 'Blue Screen of Death, a STOP error message appears when Windows encounters a serious error. It mainly occurs due to any hardware or software issues. But, sometimes you see a STOP error due to mismatch of thread and Asynchronous Procedure Call (APC) indexes. The worst thing about a STOP error is that, it halts the booting process of the system, which leads to inaccessibility of hard drive data. A backup file on another storage device in such situations comes in handy for recovering the data. However, if you have not maintained any backup file or the backup goes corrupt, then you can use a hard disk recovery software to recover your data completely.

To give you a better understanding of the whole problem, let us take an example - Suppose, you are trying to boot your Windows Vista based computer and you see a STOP error occurs on the blue screen that states:

"STOP 0x00000001, 0x00000001 (Parameter 1, Parameter 2, Parameter 3, Parameter 4) APC_INDEX_MISMATCH"

After this STOP error, the system will not boot. Hence, you will not have any access to your hard drive data.

Cause: This STOP error may occur due to any of the following reasons:

Virus Infection Memory corruption. Excess of RAM (Random Access Memory) A mismatch of thread and APC indexes created by kernel-level application or a device driver running in kernel mode. Issues with newly installed driver, hardware or software. Problems in win32k.sys (Windows system file).

Resolution: When a STOP error occurs, you are left with no other choice but to restart the system and troubleshoot the problem. So, you can use any of the following troubleshooting measures to resolve the issue:

Run an anti-virus software. Ensure that all the newly installed hardware or software are compatible with the system. Check the system's RAM. To check whether the memory is corrupted or not, run "Memory Diagnostic Tools" on Vista. Restart Windows using Last Known Good Configuration option. If this does not work, then restart the system and hold F8 key before Windows logo appears and select the "Repair the computer" option in the "Advanced Boot" menu. Then choose Startup Repair option from the menu for "System Recovery Options" and the startup repair process will start repairing the computer.

However, if none of these measures help you, then you need to reformat the drive and re-install the operating system, which would result in deletion of the hard drive data. Or, recover deleted data using a powerful disk recovery application that recover all lost, missing or inaccessible data from the hard drive via its efficient scanning algorithms. In addition, the hard disk recovery software applications enable you to use them with ease, without any prior technical knowledge.

Microsoft's latest operating system, Windows 7, has everything that a computer user can ask for. The users using systems based on Windows Vista operating system can also upgrade their systems to Windows 7 and enjoy all its advanced features. Migrating to Windows 7 can be easily performed by using a Windows 7 upgrade software. Moreover, the process does not require you to perform backup of your hard drive data. Migration to Windows 7 might be an task, but it can also leave your system in an unbootable state, if not performed systematically. In such situations, the data stored on your hard drive becomes inaccessible. To retrieve data, an up-to-date backup enables you to restore the data. But, if the backup is not maintained or inaccessible, then you will need to use advanced data recovery software to recover your data.

Consider a practical situation, where you start migrating from Windows Vista to Windows 7 operating system. However, after the first part of installation was over, the system was unable to boot the setup configuration. Left with no option, you go back to Windows Vista by deleting the setup information and cleaning the boot record. After doing so, when you attempt to reboot your system, you receive another booting error message:

"A Disk Read Error Occurred. Press Cltr-Alt-Del to reboot."

Once the above booting error message is displayed, the data stored on the hard drive becomes inaccessible. This error message pops up only when the migration process is not followed systematically.

Resolution:

To resolve the above booting error message and access the hard drive data, you will need to follow any of the below steps:

1.Enter Windows Vista setup CD. 2.Open the Recovery Console. 3.Run CHKDSK command.

However, if the above steps fail to resolve your problem then you will need to reinstall Windows Vista. This resolution ensures that the system will be bootable and you can store new data on your hard drive. However, the resolution has a major disadvantage that your previously stored data will be deleted from your hard drive. To overcome this disadvantage, you can use an effective data recovery software to recover the formatted data. A data recovery tools incorporated high end scanning procedures to salvage the formatted hard drive data.

Windows Vista boot sequence first involves loading the MBR, followed by the drive boot sector . The boot sector then accesses the Windows Boot Manager to finally load the Boot Configuration Data (BCD) store and complete loading the operating system. If any of these components get corrupt, the Windows fails to start. As a result, your data becomes inaccessible. The first tip to solve such problems is to run 'Startup Repair' If this fails, you should repair them manually or reinstall Windows as the last resort. At this point, if a valid backup is unavailable, a Partition Recovery Software can get your data back.

For example, suppose you use a Windows Vista based computer. You receive a blue screen error message when attempting to start the computer. The error indicates that a critical boot data structure (MBR, boot sector or Boot Configuration Data store) is corrupt. When you try to boot the computer from Vista installation disc and use 'Startup Repair' option under 'System Recovery Options' from Windows RE (Recovery Environment) as the basic troubleshooting step, you get an error message as below:

“Operating system: Unknown on (Unknown) Local Disk”

The data stored on the hard drive is inaccessible.

Cause

The 'System Recovery Options' cannot repair the disk. The error occurs when this fails to locate the operating system automatically.

Solution

Since the 'Startup Repair' has failed, you need to repair the corrupted boot components manually. To do so, you should use Bootrec.exe tool of Windows RE. You should first examine the primary boot time error message and error details after running 'Startup Repair' to know the exact component causing the problem. After this, you can apply these steps:

Boot your computer using Windows Vista installation disc and choose 'Repair your computer' option Open the command prompt under 'System Recovery Options' after selecting the target operating system Type 'Bootrec.exe' and use any of the following options on the basis of affected component:

/FixMbr /FixBoot /RebuildBcd

If the above measures do not solve the existing issue, you can reinstall Windows provided a complete backup is available. If not, you are recommended to use a Partition Recovery utility to recover the lost data.. A Partition Recovery Software can extract lost and missing data using high-end scanning algorithms, while providing a self-explanatory interface.

Nothing can be more frustrating for a computer user than receiving an error message at the booting of system. Few fundamental causes responsible for the occurrence of the error message could be file system corruption, improper system shutdown, human errors, and malicious software like virus. A booting error message not only halts the booting process of a computer, but also makes the data stored in the hard drive inaccessible. To effortlessly overcome the hazards of the error message and to access the hard drive data, the user can restore the data from an updated backup. But, there have been thousands of case studies where the user forgets to create an adequate data backup. For such situations, only a powerful third-party Partition Recovery application can help.

To illustrate the above case, consider a scenario where you encounter underneath error message when you boot your system and try to connect to the Internet:

“An error has occurred... If this is a new setup ask your hardware provider for Windows updates... etc.”

Note: The error message comes on a blue screen.

In addition, when you reboot your system again, another error message appears on the blue screen:

"Error on login process... Unmountable Disk Error... If this is a new setup ask your hardware provider for Windows updates... etc."

The second error message appears every time you attempt to access the records stored in your hard drive.

Cause:

The root cause for occurrence of the above error message is corruption in file system.

Resolution:

To resolve the above error message and to access the hard drive data, you will need to format your hard drive and reinstall Windows operating system. While formatting allows you to resolve the error, it also erases the data stored in the hard drive partitions. For complete recovery of data from a formatted hard drive, you will need to opt for an effective deleted partition recovery utility. A Partition Recovery Software employs high-end scanning procedures to scan your hard drive and recover maximum data. Such applications can be easily understood even by a novice user.

System32 is a Windows system directory that is located under C:\Windows\System32. The folder contains various critical system files that Windows requires to boot and run. For this reason alone, you see many Windows system error messages specifying System32 folder. The System32 directory is not itself the root of Windows issues until it is corrupt or missing. But if this occurs, it generally leads to data inaccessibility and an unbootable system. Thus, to regain the lost data, you need to either apply your last backup or recover it through a windows Data Recovery Software .

For instance, suppose you use a Windows XP
-based computer that runs in dual-boot configuration with Windows 2000. You try to boot Windows XP, but fails with a boot time error. You try to access the System32 folder in Windows Explorer by booting into Windows 2000
. This too fails with an error as below:

“directory missing or corrupt”

The next time, when you try to view Sytem32 folder, the folder is not visible.

Cause

System32 directory is corrupt.

Solution

To solve this problem, you need to repair Windows XP installation as follows:

Insert the Windows XP installation CD and boot the computer from it. To do so, you may need to change the boot order in BIOS At 'Welcome To Setup' screen, press Enter to start the Windows setup Click to accept the License Agreement that will search for all Windows installations Select the affected Windows XP installation Press R to initiate the repair process. It will replace the required files and folders

At times, the Setup cannot detect the Windows XP partition because of high damage or it may fail to repair the installation. If you come to this situation, the option is to reformat the drive and restore from backup. However, it is highly recommended to use a powerful Partition Recovery software if you find backup as unavailable or invalid, prior performing drive formatting.

Windows Data Recovery tools enable you to perform complete data recovery of lost or missing disk partitions and data. The safe and easy-to-install products come with a graphically rich interface.

Many of us think that the hard drive is the most reliable storage medium that never fails. But, the reality lies way beyond. Being a mechanical device, a hard drive is bound to fail. It can fail anytime and at any moment. You can never be certain or aware of hard drive failure or damage. When a hard drive fails, you may encounter unexpected behavior of the system, error messages and crash down of programs. A s a result you may lose your data. In other words, a hard drive failure means disaster. It is therefore always recommended to maintain a valid backup file to restore the data at the time of data loss.
