Fix an unmountable boot volume

How to troubleshoot "unmountable boot volume" in XP.

If you are unable to start Windows and get an error message saying you have an "unmountable boot volume," this can be caused by a corrupt boot.ini file or by a defective hard drive.

To troubleshoot the problem, do the following:

Boot into the recovery console at startup, using your Windows XP CD.

In the recovery console, type chkdsk /p If disk errors are discovered, you may need to replace the hard drive.
If no disk errors are discovered, reboot the computer and go back into the recovery console.
Type the following command at the command prompt:

bootcfg /rebuild

The bootcfg utility will scan the drive and display the results.

When the prompt asks if you want to add installation to the boot list (Yes/No/All), type Y and press ENTER.

When asked to "Enter Load Identifier," type the name of the operating system (for example, Windows XP Professional) and press ENTER.

When the prompt says "Enter OS Load options," type Fastdetect and press ENTER.

Remove the Windows XP installation CD from the drive and type Exit.

Reboot the computer. Windows XP should start normally.
