How to fix :UNMOUNTABLE_BOOT_VOLUME: (XP)
This is a very common issue, but is very easy to fix. There are in fact two ways that you can resolve this problem: The Quick Way, and The Long Way. Either one works.
The Quick Way
1.) Start your computer with the Windows CD-ROM if your computer can start from the CD-ROM drive.
2.) When the Welcome to Setup screen appears, press R to select the “Repair with Recovery Console” option.
3.) Select the Windows installation that you want to access from the Recovery Console.
4.) Type the administrator password when you are prompted to do so. NOTE: If no administrator password exists, just press ENTER.
5.) At the command prompt, on the drive where Windows is installed, type CHKDSK /P, and then press ENTER. Your hard drive is then scanned for File System errors. This process shouldn’t take more than 5 minutes.
6.) At the command prompt, type FIXMBR, and choose YES to all the scary warnings that you see regarding rebuilding the MASTER BOOT RECORD.
7.) At the command prompt, type EXIT, and then press ENTER to restart your computer.
8.) When the system reboots, choose “Go to windows”
9.) If the Windows Advanced Startup Menu appears, choose NORMAL MODE.
10.) Remove the Operating System CD.
11.) When you reach the desktop you can be assured that your issue is resolved.
