Diagnose the 'Unmountable Boot Volume' Error
1. Determine if you have your BIOS settings configured so as to force faster UDMA modes. In this case, you can solve the problem if you restart your computer, enter the BIOS and then load the 'fail-safe' default settings. Next, reboot the computer and the problem will be fixed.
2. Find out if you used the wrong IDE cables. This error can commonly be caused when you swap hard drives and use the wrong IDE cables to connect them. You may experience this error if your computer uses Ultra Direct Memory Access, or the UDMA hard-disk controller, with a standard 40-wire connector cable. In this case, you can fix the problem simply by using the correct IDE cables when using these hard-disk controllers.

3. If none of these possible causes corresponds with your problem, then complete the steps in Section 2.
Resolve the 'Unmountable Boot Volume' Error

When you see the message 'Press any key to boot from CD,' tap any key on your keyboard and wait until you see the “Welcome to Setup” screen.

2. Press the ALT key and the 'Print Screen' button on your keyboard. Sometimes this button is labeled 'prt sc' or 'prnt scrn.' The ALT Print Screen combination captures a screen shot (a picture of the screen) of the active window, which in this case is the error message. The screen shot is stored in your computer's memory much like if you were doing a 'cut and paste' operation in your word processor.
