I get the message disk boot failure, insert system disk. I tried putting in xp disk still won't boot. Then tried reinstalling xp and have now got two copies of xp on hard drive...arrggh. It installs and then reboots and still says disk boot failure, i have tried repairing the installation, it just keeps reinstalling and restarting and reinstalling again. Please help. There are two hard drives in this computer one for system, one for storage. It is a Carillon audio pc, 3gb ram pentium 4. Ok so I have now deleted all partitions, reformatted, wiped everything and reinstalled xp, the problem seems to be that I can't locate the drive in the bios to boot from it, please help this is driving me insane. Can I just put another hard drive in, does it need to be specific to the motherboard or something? I know very little about computers as I'm sure you have noticed! Narrowed it down to a dodgy drive, took out the slave drive and now I can boot from the master but I cannot install xp, I get BSOD saying 'page fault in non paged area'. Anyone out there??
