The boot selection failed.... Error?

Its a well known fact that if one or more required boot files are found to be missing or corrupt, a Windows

system might fail to boot. Such problems can be resolved by using Windows installation

disc. But still if it is not resolved, the the only solution remains is to install the operating system, which causes data loss.
Now, if no valid data backup is available, you need to use windows data recovery utilities.
Lets consider to boot a Windows Vista or Windows 7 based system and it fails to boot displaying the below error message on screen:
“The boot selection failed because a required device is inaccessible”
It is 0xc000000f error code. You cannot boot into the system even at subsequent attempts of restarting the system.
Reasons:

1. One of more Windows boot items, like MBR, BCD store etc., are missing or corrupt
   
2. Incorrect BIOS settings for the boot device, usually hard drive. This might occur if you have recently performed some changes in system BIOS settings.
   
   

Solution
If after changing the BIOS settings, Windows is unable to boot, then configure BIOS to default fail-proof settings and after that set hard drive as the primary boot device. And if it is not OK then we should repair Windows startup files using windows recovery environment as follows:

• Insert Windows Vista or Windows 7 installation disc into the computer and boot the system
  
• Press any key for starting the repair process when prompted for
  
• You need to then select the time, language and currency and the desired input method
  
• Click 'Next' and select 'Repair your computer' option
  
• The 'System Recovery Options' dialog box appears, at which you need to select the Windows installation you need to repair. Click 'Next'.
  
• You can then select the 'Startup Repair' option. Instead, you can also run 'Bootrec.exe' through 'Command Prompt'
  
  

If the above steps fail to boot Windows successfully, then it is suggested to reinstall the operating system and use your recent data backup to restore the lost data. If no data backup is available, use windows data recovery software for extracting the data. These software are embedded with high-end scanning algorithms. The software also enable you to perform comprehensive Partition Recovery in all cases of logical crashes.
