Data Loss Due to Unmountable Boot Volume

Sometimes, when a user boots up to Windows XP computer system, he receives the following error message:



"Unmountable Boot Volume"



The above error occurs because of three main reasons discussed below:






  • The file system in the computer is damaged and cannot be mounted.



  • The user uses a standard 40-wire connector cable to connect the UDMA drive to the controller instead of the required 80-wire, 40-pin cable.



  • The Basic Input/Output System (BIOS) settings are configured to force the faster UDMA modes.





To resolve the above error, the user needs to follow these steps:



If the above error occurs due to damaged or corrupted file system, then the user should follow these steps:





  1. The user needs to insert the Windows XP CD-ROM into the CD-ROM drive, and then restart the computer. Next the user needs to select the options which are required to start the computer system from the CD-ROM device.



  2. When the user views “Welcome to Setup” screen, he needs to press R to start the recovery console.




Note : A user can skip that if the Recovery Console is already installed on the system.





  1. If the user has a dual-boot or multiple-boot computer, the user needs to select the installation that he can access from the Recovery Console.



  2. Next the user needs to enter the Administrator password.



  3. At the command prompt, the user needs to type chkdsk /p, and then press ENTER




6. The user needs to type fixboot (if system is a multiboot PC with Vista installed…then we should skip this step)



7. At the command prompt, the user needs to type chkdsk /r, and then press ENTER.



8. At the command prompt, the user needs to type exit, and then press ENTER to restart the computer.



If the error has occurred due to use of a standard 40-wire connector cable to connect the UDMA drive, then the user needs to replace the 40-wire cable with an 80-wire UDMA cable.



If the error has occurred due to a BIOS settings problem, then the user can load the 'Fail-Safe' default settings, and then reactivate the most frequently used options such as USB Support.



But if all of the above measures fail to perform and the same error comes intermittently, then the user has to reinstall the operating system. In that case, if the user has not maintained any data back up, he needs a third party application - Data Recovery Software to recover and restore the lost data.
