Hello everyone, Now i am having this Blue screen when i boot into XP, it tells me Unmountable_boot_volume with the jumper settings on Master. I get this no matter i try to boot into XP, or try to install XP. I have tried, chkdisk /r, chkdisk /p, fixboot, fixmbr. None of these worked for me. But i have no problem booting into XP, if i put the jumper settings to Cable select. Funny thing is, my bios does not recognised hda 80gb as primary but as primary slave. Can anyone explain to me why am i having this problem? I realli appreciate it, i am very frustrated.
