I have a Dell Dimension 8400 and the other day it started giving me UNMOUNTABLE_BOOT_VOLUME error so I tried rebooting my computer from the Windows XP disk. I performing "chkdsk /p" but it stopped at 38% and stated "The volume appears to contain one or more unrecoverable problems" What should I do? Should I continue with "fixboot"? Also when I choose the recovery option in the setup, it never stated which Windows installation I would like to log into. So on the command screen it showed that I was in the C:\> directory and not in the C:\WINDOWS> directory (which I was expecting.) I tried to get into the WINDOWS directory by typing "cd windows" but it stated "The path or file specified is not valid." Is that normal? That's the directory where I performed "chkdsk /p" I'm afraid to perform "fixboot" in the same directory. Also I changed my SATA drive to "combination" rather than "RAID Autodetect / AHCI" because every time I tried to perform the recovery it stated "Setup did not find any hard disk drives installed in your computer" I learned this from http://www.techspot.com/vb/topic18329.html So should I still perform "fixboot" in the C:\> directory?
