When a Windows Vista system is switched on, the boot sector loads the bootmgr file to access the Boot Configuration Data (BCD) store, which uses its information to load the operating system. The BCD store is a firmware-independent database, which is used to store the boot time configuration data, and is very significant for the boot process. However, sometimes the BCD store gets corrupt and results in making the system unable to boot. In such cases, you should use appropriate corrective measures to resolve the issue. However, if you are not able to address the problem then you should use a Windows data recovery software to recover the trapped data.

Consider a scenario wherein your Windows Vista system is unable to boot. An error message is displayed, that is: “File: \Boot\BCD Status: 0xc0000034 Info: The Windows Boot Configuration Data file is missing required information”

Cause:

The most possible cause of the aforementioned error message could be either (or both) of the following reasons:

The entry of the Windows Boot Manager (Bootmgr) is missing in the Boot Configuration Data (BCD) store.

The Boot\BCD file on the active partition is either corrupt or missing.

Resolution:

To resolve this error message and to be able to access the Windows Vista system, you should perform the following methods, preferably in the given order:

Repair the BCD store by using the Startup Repair option: In the Windows Recovery Environment, use the Startup Repair option to repair the BCD store.

Rebuild the BCD store by using the Bootrec.exe tool: If the previous method is not able to resolve the issue, then you should use the Bootrec.exe tool in the Windows Recovery Environment to resolve the issue.

Rebuild the BCD store manually using the Bcdedit.exe tool: If you are still not able to rebuild the BCD store, then you should do it manually using the Bcdedit.exe tool in the Windows Recovery Environment.

Either of the aforementioned methods will be able to resolve the error. However, if you are still not able to address the issue then you should use a third-party partition recovery tools to recover the lost partition. Such read-only tools are able to recover partition from all instances of corruption using sophisticated scanning algorithms.

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.

The disk partition containing hardware-specific files that Windows requires to boot successfully is termed as System partition. This partition must always be set as active. A Windows Vista running computer requires a valid system partition to boot. By valid it means, the partition that contains all required system files. If any of these files goes missing or gets corrupt, a computer may start on-disk Win RE (Windows Recovery Environment) instead of Windows Vista. Such fail-overs cause inescapable situations of repairing Windows installation or using the latest backup as Windows loses the capability to boot. However, if all the measures fail, you can safely use a Windows Data Recovery product to recover the lost data.

As an example, you can consider a scenario when you try to start a Windows Vista-based computer. The system may fail to boot and get forced to start in Windows Recovery Environment. You attempt to repair by using Startup Repair option, but this too fails with an error as below:

“The partition table does not have a valid System Partition.”

Cause

The error suggests that the system partition that is listed in disk partition table does not contain the system files that Windows Vista requires.

The Startup Repair typically fails to repair when the error root from malfunctioning hardware, logon issues, malicious software or Windows upgrades.

Solution

To solve this issue, you should apply the fixes like:

You should try to replace the missing or corrupt system files with a backup copy. You can boot the computer manually by using Windows installation CD and run the Startup Repair.

You can also use System Restore option that rolls the system state back to last working If it still displays the aforementioned partition error, you need to reformat and reinstall Windows. Restore the lost data from the last backup.

For full data restoration, backup must be complete and clean. If not, you can use a Windows Partition Recovery tool. These disk-scanning utilities can salvage the lost data back in original condition quickly and easily. However, you are recommended to apply these Windows Data Recovery applications before reformatting the disk.

The Advanced Host Controller Interface (AHCI) is a mode that defines the operation of Serial ATA host-controllers and offers a typical method to configure, program and detect SATA adapters. An error message might occur when you change the mode of the Serial Advanced Technology Attachment (SATA) to AHCI mode.

As a recent scenario with Vista, when a user changes the SATA mode of the boot drive in the BIOS setup to use the AHCI specification he receives the following error message when the computer restarts: “STOP 0x0000007B INACCESSABLE_BOOT_DEVICE”

Cause

The main reason for the above problem is that AHCI driver (Msahci.sys) in Windows Vista is disabled. The user needs to enable the AHCI driver
before changing the SATA mode of the boot drive.

Resolution

To resolve the above issue, the user needs to make changes in the registry. The user needs to enable the AHCI driver in the registry before changing the SATA mode of the boot drive. This can be done with the help of these steps:

1. Firstly the user needs to exit all Windows-based programs.

2. The user needs to click Start, type regedit in Run or Start Search window, and then press ENTER.

3. If the user receives the User Account Control dialog box, he needs to click Continue.

4. The user needs to locate and then click the following registry subkey:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci

5. In the right pane, the user needs to right-click Start in the Name column, and then click Modify. In the Value data box, type 0, and then click OK.

6. The user needs to click on the File menu to close Registry Editor.

The user might receive the same error message intermittently especially those with more than one hard drives. In such circumstances, the user needs to do a clean reinstall that will lead to data loss without proper backup already taken. To recover the lost data, the user can restore all the data through the recent back up. In case, if the user has not maintained any back up the user needs to use a third party application to recover the lost data. Such third party applications are known as Data Recovery Software.

The technique used for connecting two or more CPUs (Central Processing Units) in a single computer system is known as multiprocessing. Various advantages of working in multiprocessor environment are performance enhancement, increased speed and installation of more applications. To work in a multiprocessor environment, you should use the processors that are of the same type and same level. However, if the processors are not symmetric to each other, a STOP error might occur. In such circumstances, the data stored in the hard drive becomes inaccessible and your system becomes unbootable. To rectify the data loss problem post STOP error, you need to use Data Recovery Software. These applications can completely recover and restore your inaccessible data in case of no backup availability.

As a practical instance, you encounter the below STOP error message when you upgrade your system by installing a new processor in your system:

“STOP 0x0000003E MULTIPROCESSOR_CONFIGURATION_NOT_SUPPORTED”

You encounter the above error message each time you attempt to boot your system. In addition, the data saved on the hard drive becomes inaccessible.

Cause:

Two main reasons for the occurrence of above error message are:

• The processor installed in the system is asymmetric to the processor already installed. • The new processor has floating point capabilities where as the previous one does not. Resolution:

To resolve the above issue, you need to uninstall the new processor from your system. However, uninstalling the new processor requires changes in registry settings of your system. Moreover, uninstalling the processor might corrupt ntoskrnl.exe file. Incorrect changes made in registry settings or corrupt ntoskrnl.exe file result in making your computer system unbootable. To successfully boot your system, you need to go for a clean operating system reinstall. A clean reinstall will erase all data from the selected hard drive partition. In such situations, to completely recover and restore your lost files and folders you need to use effective Data Recovery Software.

Such Data Recovery Tools ensure comprehensive recovery and restoration of lost data from formatted hard drive partitions. These tools incorporate advanced scanning algorithms to achieve absolute File Recovery. Such tools serve as user-friendly utilities with their highly interactive interface and to the point documentation.

Windows Vista is the latest operating system from Microsoft for workstations and basic servers. It has been introduced with major design changes and features. Windows Vista supports improved searching, networking and several multimedia creation tools, which enhances its popularity among users. But sometimes, this operating system suffers crashes due to reasons like Windows system file issues, file system inconsistencies, malicious software like virus and worm, driver issues, user errors etc. The damage could be extensive enough to cause data loss. In such cases, if data backup is unavailable, the Data Recovery solutions come to rescue.

Consider a scenario where you face the following error with Windows Vista based system:

“File System Error (65535)”

This error is encountered when you attempt to open or install any program. As an additional symptom, you may observe desktop icons missing. The same error message can also result after incorrectly modifying permission settings in System32 folder.

Cause

The issue might result due to corrupt or invalid Windows Vista files.

Solution

To resolve the issue, you can try these methods:

• You can use System Restore to get the system back to last known-good state.

• If problem persists and the same error is encountered, you can use System File Checker (or sfc.exe) tool with /scannow option to correct the issue. System File Checker is a command line tool that allows user with administrative rights to scan Windows Vista files. Its /scannow switch scans all protected system files and replaces incorrect versions with correct ones. The command can be used as:

sfc /scannow

• If the above step fails, you can perform clean reinstallation of Windows Vista. But before this, you need to take complete data backup. You are suggested to check backup log reports.

A clean reinstallation of Windows erases all data from the selected partition. Also, the backup media should be checked to see if it can restore required information. If data backup is invalid, not updated or absent, Data Recovery Software can be used to restore lost information.

Data Recovery applications are tools to scan the affected media as hard drives and flash drives and recover lost data. They incorporate advanced scanning algorithms to efficiently scan the affected drive. Such applications work at operating system and file system level to locate and recover data. These are graphically rich applications and hence are easily usable. These software are completely safe and non-destructive to use.

Computers running release version of Windows Vista suffer from a limitation related to corrupt partitions. As a result of which, not at initial start, but while restarting, a black screen displays or system stops responding at all. Similar kind of issue is also seen with Windows Vista Service Pack 1, in which Autocheck.exe process hangs. Partition corruption causes data loss. However we can recover it using Partition Recovery Software.

Autocheck.exe is an automated process that runs at each start, if finds errors with the system. The issue lies in the way that Autocheck.exe uses to detect partition corruption. This criterion is entirely different from what is used by NTFS. Hence at initial start, though NTFS marks the partition as damaged, Autocheck.exe doesn’t take it as corrupt and also doesn’t carry out any step to fix it. When the system is restarted, NTFS again follows the same procedure to mark the same partition as corrupted and Autocheck.exe restarts. However, this time system doesn’t behave as expected and a black screen is encountered. If user attempts to log on to the system after canceling the autocheck.exe process, it fails. In release version of Windows Vista, Safe Mode can help in this respect.

* In order to resolve this issue, it is recommended to download AIK (Automated Installation Kit) and create Windows PE 2.1 disc to restart the affected computer system
.
* For Partition Recovery, we can use chkdsk/f command.

* If corruption problem persists, we need to format the partition after backing up the data.

* To avoid the same problem occur in future, corresponding hot fix can be installed.

If backup fails to restore required partition information, Partition Recovery Software can be used instead. These are the graphically rich applications to scan and recover lost data. The applications follow up definite recovery approach using scanning algorithms. This software benefit us in terms of quality features, safe data conduct, secure scanning and complete data restoration. Use of these applications and Partition Recovery procedure follow up is very easy because of the interactive interface they have. Stellar Phoenix Windows Data Recovery is the powerful application to restore damaged, missing or lost partitions. The software supports Windows Vista, Server 2003, XP and 2000. It is a complete Partition Recovery Software. The application offers intuitive interface. It can be used with FAT16, FAT32, VFAT, NTFS and NTFS5 file systems.

Windows Vista supports Dynamic Disk Volumes for its Business, Enterprise and Ultimate editions. In order to convert Basic Disk to Dynamic Disk, we can simply use ‘Convert to Dynamic Disk’ option of the disk through Disk Management. However converting back a Dynamic Disk to Basic Disk is not usual as it needs disk formatting and causes data loss from partitions. Data in such cases can be recovered using Partition Recovery Software.

Users report that in some cases, after converting a Windows Vista installed disk partition from Basic to Dynamic Disk Volume, certain issues are observed:

* Dynamic Disk Volume can’t be removed while users attempt to reinstall Windows Vista. The Delete command which appears at the time of installation .where you want to Install Windows dialog box if user reinstall, Windows is not available anymore.
* If Dynamic Disk is to be converted to Basic Disk, all volumes are need to be deleted first and Dynamic Disk is converted to Basic Disk by using Convert to Basic Disk command through Disk Management tool. But in this case, this option becomes unavailable.

In order to solve these issues, users need to first backup all the data and format the volume. If Windows Vista is being reinstalled, the Setup program gives this option. Alternatively, diskpart.exe command can be used remove it. It can be accomplished from command prompt.

Users are advised to carry out the backup process in effective manner. Backup log report must be checked and also backup must be analyzed for all required files. However if partitions lose data when no valid data backup is available, Partition Recovery applications can be used to extract lost information.

Partition Recovery Software is the safe applications to restore lost, missing and damaged partitions’ data. This software scans the affected drive to recover lost information, from Basic as well as Dynamic Disks. The applications are usually designed as read-only and hence can safely carry out recovery. Partition Recovery software is rich in interface. So users can easily use these applications without the aid of any technical knowledge. This software offer several advanced features to ease the process.

Stellar Phoenix Windows Data Recovery is the powerful and safe Partition Recovery Software. The software supports Windows Vista, Server 2003, XP and 2000. It has a rich graphical interface.
