Recover inaccessible partition in case of corrupt BCD store in Windows Vista

In the Windows Vista and later versions, the BCD (Boot Configuration Data) store contains the boot entries that are required to boot the operating system. When a system is started, the Bootmgr reads the boot entries from the BCD store and a boot menu is displayed to the user. It is much more secure than the previous boot.ini, which used to boot Windows XP and prior versions. However, at times the BCD store get corrupt thereby making the system unable to boot. This could happen because of various reasons such as corrupt active partition, virus infections, power outages, etc. In such cases, you should take appropriate steps to solve the issue. If the issue is not resolved, then you should use a third-party Windows partition recovery software to recover partition.

Consider a scenario wherein your Windows Vista 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 causes of this erroneous situations are:
The Windows Boot Manager (Bootmgr) entry is not present in the Boot Configuration Data (BCD) store.
The Boot\BCD file is either corrupted or missing on the active file system.

Resolution:

To resolve this situation, you should perform either of the following methods, preferably in the given order:
Repair the BCD store: You should repair the BCD store by using the Startup Repair option in the Windows Recovery Environment.
Rebuild the BCD store using Bootrec.exe: You should rebuild the BCD store by using the Bootrec.exe tool in the Windows Recovery Environment.
Rebuild the BCD store manually: You should manually rebuild the BCD store by using the Bcdedit.exe tool in the Windows Recovery Environment.

After performing either of the aforementioned method, you should restart the computer to implement the repair changes. However, if you are still facing the similar situation it means that the file system is inaccessible. In such cases, you should use a third-party partition recovery software to recover Windows partition. Such tools are read-only in nature that do not overwrite the original contents while scanning the corrupted media.

Stellar Phoenix Windows Data Recovery is a Windows partition recovery software that enables you to recover data from lost, deleted, or inaccessible partitions. It supports partition recovery from various partitions such as FAT, NTFS, and exFAT file systems. This partition recovery software is able to recover more than 185 different file types from various storage media such as hard drives, external HDDs, pen drives, iPods, etc. In addition, this tool is capable of recovering deleted emails from Outlook Express and MS Outlook. It is compatible with Windows 7, Vista, Server 2003, XP, and Server 2000.

MFT Corruption Prevents you to Delete and Access Data From NTFS Partition

You can easily remove files from a Windows hard drive partition to free up disk space and use it for storing other files. You can do it by simply removing the file using Shift + Delete key combination or by emptying the Recycle Bin folder. However, if the partition is corrupted or its file system is faulty, you can not delete a file. Corruption also renders entire hard drive partitions inaccessible and unusable, causing serious partition loss problems. At this point of time, Windows partition recovery becomes essential to retrieve lost hard drive partitions and stored data.

When you attempt to remove a file from NTFS file system partition, you may come across the below error message:

Cannot delete file name: The file or directory is corrupt and unreadable.”

At the same time, you may see any of the below entries in the Application Event Log of Microsoft Windows operating system:

Event ID: 41
Source: Diskperf
Description: The file system structure on disk is corrupt and unreadable. Please run the chkdsk utility on the device with label <Volume_name>”

Or

Event ID: 55
Source: NTFS
Description: The file system structure on disk is corrupt and unusable. Please run the chkdsk utility on the volume <Drive_letter:>”

When you apply Chkdsk utility against affected Windows partition, it may or may not fix the problem. The data remains inaccessible after this behavior and you need figure out the cause of this problem and recover partition by fixing it.

Grounds of the problem:

The above problem is caused if MFT (Master File Table) is damaged. The long and short file name pairs, which are stored in directory index and file names, which are stored in associated FRS (File Record Segment) has case-sensitive letters that don’t match.

Resolution

After MFT corruption, Windows operating system can not read the partition entries and thus can not access them. To fix this problem, you need to format the hard drive and recreate hard drive partitions. However, it removes all hard drive partitions and partition recovery is the only way to fix this problem.

Recovery is best possible using third-party partition recovery software. They use high-end scanning techniques to recover lost hard drive partitions and stored data. The applications have interactive user interface and read-only conduct to offer easy and safe recovery.

The software works well with Microsoft Windows 7, Vista, 2003, XP, and 2000. It supports recovery of all NTFS5, NTFS, FAT32, VFAT, FAT16, and FAT12 file system partitions.

Recovering Windows partition in case of ‘Operating system not found’ error

A partition in a computer system is a logical space in a hard disk. It is created to keep the system files and data files separated from each other. Keeping the system files away from the data files ensures that there is enough space for virtual memory paging and swapping. Also, if one of the non-system drives gets corrupted then other partitions do not get affected by this. However, like everything else the partitions are also prone to corruption. And the corruption can happen due to various reasons, such as power outages, improper system shutdown, damaged system files, virus infections, etc. In such cases, you should take certain measures to rectify the issue. However, if you are not able to resolve the issue then you should use a third-party Windows partition recovery software to recover Windows partition.

Consider a scenario wherein you are unable to boot your Windows XP system. An error message is getting displayed, that is:
Operating system not found
Missing Operating System
When you boot your system from the Recovery Console to recover its functionality, the following error message is displayed:
Setup did not find any hard drives installed on your computer.

Cause:
There could be the following reasons for the aforementioned error messages:
The hard disk is corrupted.
The BIOS settings are configured in a way that the BIOS is unable to detect the hard disk.
The Sector 0 of the physical hard disk has a corrupted MBR.
An incompatible partition is marked as Active.
The partition containing the MBR is not active anymore

Resolution:
To resolve these error messages, you should use the following methods:
Check the BIOS settings:You should check the BIOS settings and ensure that the BIOS enlists and recognizes the hard disk.
Use Recovery Console: You should use the fixmbr command in the Recovery Console to repair the MBR of the system drive.

Either of aforementioned methods will be able to resolve the issue. However, if you still are not able to resolve the issue then you should use a third-party Windows partition recovery software to recover partition. Such read-only tools are able to safely recover trapped data using sophisticated scanning algorithms.

It is compatible with Windows 7, Vista, Server 2003, XP, and Server 2000.

Incorrectly Modifying the Partitioning Scheme Cause Partition Loss in Windows

Microsoft Windows operating system enables you to create the Swap Files on your Windows hard drive. Swap file is the hard disk space, which is used by Windows operating system as a virtual memory extension for the RAM (real memory) of your computer. This mechanism improves the performance of your Windows computer. The swap files can be organized as contiguous disk space, thus your system needs less Input/Output operations for reading or writing entire file. However, in some situations, you may face critical problems of partition corruption or partition loss while creating the swap files. This behavior leads to significant partition loss situations and require partition recovery to be fixed.

As an practical example of this problem in Microsoft Windows operating system, you may come across the below error message when you try to create a swap file:

“The partitioning scheme used on your hard disk prevents the creation of a permanent swap file.”

The above error message prevents you from creating the swap files.

The problem occurs even if your using Virtual Memory dialog box when you install Microsoft Windows or 386 Enhanced alternatives in the Control Panel to create the swap files.

Root of the issue:

The above problem may take place due to any of the below reasons:

A Windows partition manager
Un-initialized files of the partition table
A virus or any other malicious program

Microsoft Windows operating system is quite cautious about the type of hard drive, when it creates permanent swap files. If you modify the Windows hard drive improperly, which is formatted through a special software, you may face serious data loss and disk error problems. To prevent data loss issues, Windows insures that correct format of the hard drive is recognized.

If you modify the Windows hard drive incorrectly, serious partition loss situations occur. Partition loss mostly occurs if:
Your system is dual-boot and both OS’s are using varying partition schemes.
Your system has deadly viruses.
In both cases, you lose your hard drive partitions and need to recover partition using powerful third-party applications.

The partition recovery software helps you to methodically scan entire hard drive and extract all lost partitions from it. The Windows partition recovery tools has interactive and rich graphical user interface to ensure quick and easy recovery in all partition loss situations.

Recovering corrupt partition in Windows XP system

A Master Boot Record (MBR) is the 512-byte boot sector that is the first sector of a partitioned data storage device such as a hard disk. It has a significant role in system bootstrapping, disk identity, and disk partitioning.

It is the main program that is used for bootstrapping the operating system after BIOS executes the machine code instructions. Sometimes, the first sector of the partition gets corrupted because of various reasons such as power fluctuations, human errors, abrupt system shutdown, virus infections, damaged operating system, etc. In such situations, you should use the Recovery Console to fix the MBR to resolve the issue. However, if you are unable to solve the issue then you should use a third-party partition recovery software to recover Windows partition.

Consider a scenario wherein your Windows XP system fails to boot up when you start it. An error message is displayed, that is:

•    Operating system not found.

•    Missing operating system.

And when you start the computer from Recovery Console to fix the errors, you will get the following error message:

•    Setup did not find any hard drives installed on your computer.

Cause:

There could be various reasons for such behaviour such as:

•    The hard disk is damaged.

•    An incompatible partition is marked as Active.

•    Sector 0 of the physical hard disk drive has an incorrect or malformed master boot record (MBR).

•    A partition that contains the MBR is no longer active.

•    The basic input/output system (BIOS) does not detect the hard disk.

Resolution:

To resolve this issue, you can perform the following methods:

•    Verify the BIOS settings: Check whether your system’s BIOS settings are proper to make sure that BIOS lists and recognizes the hard disk.

•    Use Recovery Console: Use the Recovery Console to run the fixmbr command to repair the MBR of the system drive.

The aforementioned methods should be able to resolve the error message. However, if you are unable to address the situation then you should use a third-party Windows partition recovery software to recover the partition.

Extending Windows Partition Using DiskPart.exe Causes Volume Information Loss

Microsoft Windows 2003 Server supports failover clustering to offer high availability of applications, services, and other system resources using an architecture. This architecture maintains consistent image of cluster on all the nodes, which enables them to transfer the resources ownership as and when required.

Windows 2003 Server enables you to extend hard drive partitions in a clustered environment, with the help of DiskPart.exe utility. You can use the Extend command of DiskPart.exe utility to extend Windows hard drive partitions. Under some circumstances, you may lose the volume information while extending hard drive partitions. This behavior leads to critical partition loss and require partition recovery, if backup is not available.

DiskPart.exe, a command-line utility in Windows operating system, enables you to manage hard drive, partitions, and volumes. The utility takes command-line parameters as well as scripts as input. This command is followed by volume or partition, which is chosen and kept on focus.

You can use this utility for extending your Windows hard drive partitions, only if your system can fulfill the pre-defined requirements. Among such requirements, additional free disk space availability at end of the existing drive is the most significant one. In some situations, you may lose the volume information after extending a Windows volume.

In a practical scenario, you may come across the below error message when you move a Windows hard drive volume after extending it through DiskPart.exe tool:

“The system cannot find the path specified.”

The above error message generally occurs when you try to access data from a Windows partition after moving it.

Cause

It possibly occurs due to missing or damaged volume information on Microsoft Windows hard drive. The information may be lost when you try to extend a Windows partition, which does not contain extra free disk space at the end of it.

Resolution

To sort out this behavior and perform Windows partition recovery, you are required to restore data from backup. For absolute recovery, the backup must be valid and updated. However, if the backup is not current, partition recovery software are required to retrieve lost Windows partitions.

The applications are specifically designed to scan entire hard drive using advanced scanning techniques and extract all lost partitions from it. They recover partition in a quick, safe, and easy way.

Stellar Phoenix Windows Data Recovery software recovers lost, deleted, corruption, or missing Windows hard drive partitions in all partition loss scenarios. The software with non-destructive conduct and interactive user interface, recovers NTFS5, NTFS, FAT32, VFAT, FAT16, and FAT12 file system partitions. It works well with Microsoft Windows 7, Vista, 2003, XP, and 2000.

Partitions Inaccessible Post System Update

Windows system updates allow the users to make their system compatible with all the new applications, secure from viruses, and offers many other things. These updates are installed in your system automatically through ‘Automatic Update’ feature. Once these updates are installed on your system, your computer needs a restart.

While these critical updates prove successful in most cases, they can also result in corruption of critical system file(s). In such cases, the operating system becomes unbootable and the data saved in the hard drive becomes inaccessible.

For such situations, the user needs to overwrite the corrupted file by a new and valid copy of that file. However, if the user is unable to perform the above task, then s/he is not left with any option, but to perform a reinstall of Windows operating system. While this resolution works in every case, it also results in loss of data from all the partitions. To recover all the formatted partitions and data within them, in case of no data backup availability, the user needs to opt for a commercial Partition Recovery Software.

The above scenario can be explained with the help of the below error message:

“OS Loader v4.01

Disk I/O Error: Status 00000001

Windows NT could not start because the following file is missing or corrupt:

Ntoskrnl.exe

Please reinstall a copy of the above file.”

This error message appears when you boot your Windows XP system after installing some critical updates. The message does not allow the system to complete the boot process, which further renders to inaccessibility of hard drive partitions and data stored within them.

Cause:

As specified in the error message, the ‘Ntoskrnl.exe’ file is corrupted. The file is required at the time of Windows XP startup.

Resolution:

To get past the above boot error message and to access the hard drive partitions and data within them, reinstall the copy of the file using below steps:

1.    Insert Microsoft Windows XP CD and press any key.
2.    Press ‘R’ to select the ‘Recovery Console’.
3.    Choose Windows XP and enter the administrative password.
4.    Type ‘expand d:\i386\ntoskrnl.ex_ c:\windows\system32′ command
5.    Enter ‘Y’ to overwrite the file.
6.    Type exit and try to reboot your system.

In case the above steps fail to resolve your issue and your data remains inaccessible, then you will need to reinstall the operating system and restore data from the backup. However, in case of no backup, you will need to opt for a powerful Partition Recovery Software. Such Partition Recovery tools use effective, yet safe recovery tools to recover formatted hard drive partitions and data within them.

Stellar Phoenix Windows Data Recovery is one such Partition Recovery tool that recovers all lost partitions based upon NTFS, NTFS5, FAT12, FAT16, FAT32, and VFAT file systems. It can be installed on Windows 7, Vista, 2003, XP, and 2000.

How to Recover NTFS Partition Using Partition Recovery Software

Hard drive is a critical component of Microsoft Windows computer to store precious data and install software. You can store huge amount of data on your hard drive and easily manage it. For easy and effective management of your valuable data on the hard drive, the hard drive can be divided into various partitions. Creating partitions helps you in preventing data loss situations, if your operating system crashes.

However, in some situations, the NTFS data partition may also get damaged due to numerous reasons like virus infection, file system corruption, and more. At this point, you may face severe partition loss situations and require NTFS Data Recovery to sort out the problem.

The NTFS (New Technology File System) is an advanced and powerful file system, which is used on Microsoft Windows operating system. NTFS uses file system journaling feature to keep your valuable data safe in case of improper system shutdown and system crash. However, there are various other reasons, which may damage your NTFS file system partitions and cause severe partition loss situations. These reasons include the following ones:

•    Virus infection- Viruses are malicious programs that may damage file system and other system data structures.

•    File system corruption- File system is the most significant data structure of Windows system, which keeps record of all the files on NTFS partitions. When it gets damaged, partitions becomes RAW and operating system can not locate the stored files.

•    Partition table corruption- Partition Table is a critical data structure, which stores information about all NTFS partitions. When it gets damaged, partitions can not be located or accessed.

•    Hard drive formatting- It is the process of removing all the partitions and stored data from hard drive. Unintentional hard drive formatting can cause partition loss.

In all such cases, NTFS Partition Recovery software can help you to effectively recover lost Windows partitions. When partition loss occurs, only the partition entries from partition table are deleted. The partitions remain physically intact on the affected drive, and can be easily retrieved using advanced and efficient NTFS Data Recovery tools.

How to Diagnosis and Fix Boot NTFS File System Partition Corruption in Windows

In Microsoft Windows operating system, you can divide your hard drive into various partitions for effective management of valuable data. Every Windows computer has at least one system or boot partition, which contains operating system to boot your computer from. Other partitions contain data and information. In case of corruption of any of these partitions, you may lose valuable data. This behavior causes severe partition loss, and requires Partition Recovery, if you do not have an updated backup in place.

Any damaged boot or data partition, which uses NTFS file system may cause “stop 0×24” error message while accessing it. When you face this error message while rebooting your computer or trying to run the Windows Recovery Console, you may not be able to determine the root of this issue using general diagnostic steps. Instead, you should go for the below method to handle NTFS partition corruption.

•    Turn off or disconnect data disks, which has NTFS file system partitions.

•    After identifying the problem disk, move your hard drive to other Microsoft Windows operating system-based computer, which is using FAT32 or FAT file system.

•    Use ChkDsk /f utility to detect and fix file system related problems.

Use Windows Recovery Console on Single Drive System:

If your system has only one NTFS file system partition and no other Windows disks or computers are available, you can start your system from Setup disk to run Chkdsk utility with Ntfs.sys driver disabled. Use the below steps to repair NTFS file system partition and Recover Partition using Recovery Console:

•    Start your system using Windows 98 startup disk, insert Windows installation disk into the drive.

•    Change CD_ROM:\Support\Bootdisk folder, and run Makebt32.exe or Makeboot.exe for creating Windows Setup disks.

•    Modify Txtsetup.sif file using Notepad.

•    Start the affected system using Setup disk. Press F10 key on welcome screen to enter Recovery Console.

•    Run ChkDsk /p command to repair damaged partition.

•    Quit Recovery Console and reboot your system.

If the above method does not work, you need to use Partition Recovery Software to recover corrupted or lost hard drive partitions. The applications use advanced scanning mechanisms to thoroughly scan the affected hard drive and extract all lost partitions from it.

The Windows Partition Recovery utilities do not demand sound and prior technical skills as they have interactive and simple graphical user interface.

Recovering corrupt partition in case of corrupt MBR

A Master Boot Record (MBR) in your computer system is the 512 byte boot sector that is the first sector of a partitioned data storage device such as a hard disk. It MBR plays an important role in disk partitioning, system bootstrapping, and disk identity. It is the main program that is used for bootstrapping the operating system after BIOS executes the machine code instructions. The MBR is located in the Main Boot Record area in front of the first partition. Sometimes, the first sector of the partition gets corrupted.

This can happen because of various reasons such as virus infections, power fluctuations, damaged operating system, abrupt system shutdown, etc. In such situations, the system gets corrupted and fails to boot. In such cases, you should look to use a third-party partition recovery software to recover partition from its corrupt state.

Consider a scenario wherein your system fails to boot up when you switch it on. A black screen is displayed and either of the error message is displayed:

•    Operating system not found
•    Missing operating system

Cause:

There could be following causes for the mentioned error messages:

•    The hard disk is not detected by the basic input/output system (BIOS).
•    Sector 0 of the physical hard disk drive has an incorrect master boot record (MBR).
•    An incompatible partition is marked as Active.
•    The system drive is no active.
•    The hard disk is damaged.

Resolution:

To resolve the issue, you should perform the following methods:

•    Configure the BIOS settings and check whether the BIOS recognizes the hard disk. Save the settings and restart the computer. If the error is still there, then it is a hardware related error and cannot be resolved by the BIOS settings.
•    Use the fixmbr command to repair the master boot record of the system drive.

However, if you are still not able to address the issue then you should use a third-party Windows partition recovery software to recover Windows partition. Such tools are read-only in nature and do not overwrite the original data while scanning the damaged area.
