Hi everyone. I need some help. I am running a home built machine with XP Home as the operating system. I noticed that several things weren't running smoothly and decided to use the repair feature of XP. However, that necessitated powering up and booting from the XP disk which involved getting into the BIOS to change the boot-up sequence. Then I found theat I couldn't access the BIOS. Tried DEL, F2 and other combinations but to no avail. So I purchased a new 160 gig hard drive, but it isn't recognised by the BIOS. Help. Geneset.
