An 'unmountable boot volume' error message may hinder the booting of Windows XP. It does not mean that the hard disk is defective. It probably is a simple boot sequence problem in the hard disk. It is required to use the Windows XP installation CD to tackle this problem. After inserting the CD in the computer and changing the bootsequence, it is required to restart the computer. Then the user must choose the option of using the CD ROM drive as the first boot device. Once the reinstallation files are copied the 'R' key must be pressed to solve the problem. This will open the Windows Recovery Console allowing the user to make the necessary changes.
