The BCD (Boot Configuration Data) store in Windows Vista is used to start the Windows system. It contains all the essential system startup options to boot the system. However, when the BCD store gets corrupt because of any miscellaneous reasons, then you would not be able to start the system. In such cases, you should use appropriate measures to rectify the problem. In case, this is also not possible then you should use a third-party partition recovery software to recover all the data from the inaccessible system.
Let us assume a scenario in which you are trying to start Windows Vista but fail to do so. The following error message is displayed in this regard:
“File: \Boot\BCD
Status: 0xc0000034
Info: The Windows Boot Configuration Data file is missing required information”
Cause:
This problem could have happened because of the following reasons:
The Boot\BCD file on the active partition is either damaged, corrupt, or missing.
The Windows Boot Manager (Bootmgr) entry is not present in the BCD store.

Risk-free partition recovery software to deal with any instance of Windows partition loss
Microsoft released Windows 7 as an advanced operating system over Vista. At the beginning, many users have witnessed instances of data loss while working on Windows 7. Though, Microsoft has released several patches to overcome such problems, still some unresolved problems do exist with Windows 7, which corrupts your partition. Under such situations, you can use any effective partition recovery utility to recover back the lost or inaccessible data from the troubled partition.
One of many real life issues with Windows 7 is that once you leave your system in hibernate mode, after some time, you may find it hanging at the BIOS screen. The reason behind the issue is that at times, the Windows 7 OS fails to locate the boot partition because of missing boot entry. Moreover, in such a situation, if you run the Windows 7 installation disc, it does not even work or fails to detect the partition.
To your utter dismay, you may even notice a partition named as ‘System Reserved’ with no data in it. This is the partition created by the Windows 7 and the not the partition carrying all your data.
Resolution:
In order to resolve the problem, you need to repair the partition by performing Windows 7 start-up repair with the Windows 7 installation disc. Following steps will guide you through the process:
Boot your computer after inserting the Windows 7 installation disc

Partition data loss due to incorrect Disk Partitioning in Windows Vista and steps to perform Partition recovery
Disk partitioning is often required by users who want to efficiently manage their operating system files, program files, and user data. In addition to increasing the system performance, it allows the users to go for multi-boot setups. But people often confuse on what tool to use and which partitioning scheme to employ. Windows Vista makes disk partitioning easy by incorporating a built-in disk management utility, which allows the users to format drives, create and delete partitions, resize partitions etc. Incorrect partitioning and resizing give rise to several disk-related errors causing partition inaccessibility and subsequent data loss. To overcome the problem and recover the lost data back, you need to go for partition recovery through a reliable third-party utility.
Let's illustrate a practical scenario. Suppose, you are using Windows Vista-based computer. When you try to shrink or resize a partition on your hard disk using Gparted partitioning software, you may receive the following error message:
“File:\windows\system32\winload.exe
Status:0xc000000f
Info:The selected entry could not be loaded because the application is missing or corrupt.”
Cause:
You made an attempt to resize the boot partition of your system. This has made 'Windows.exe' file of Windows Vista corrupt.
'Winload.exe' is the boot loader program that is responsible for loading the operating system kernel and device drivers. If this file is damaged, you nay not be able to boot the system. You can still recover partition data through a backup. If the backup is missing, you should follow the below mentioned resolution steps.
Resolution:
Repair Windows installation using the steps given below-
Boot the computer using Windows Vista installation disc.
On the 'Welcome to Setup' screen, press 'R' to enter the Recovery Console.
Run the 'fixboot' or 'fixmbr' command at the command prompt.
The computer will automatically restart after the repair process.
If the above resolution fails to fix the problem, you should take help of an efficient partition recovery software. These software are highly secure and easy to use. They have several built-in utilities like cloning, imaging etc. that enable you to create an exact replica of your hard disk. They perform a safe Windows partition recovery of all your lost, deleted, or accidentally formatted data.
