Ok, I'm putting together this computer for my parents and it's driving me insane. I've got a Biostar iDeq SFF box and a brand new WD 40gb hard drive. I did a full NTFS format and a fresh install of WinXP Pro, but it will not boot into windows with only the hard drive! When I try to boot, it tells me boot disk failure, it only boots when the WinXP cd is in the cdrom. I reformated and reinstalled once already, to no effect. Any ideas? I'm at my wits end.
