XP won't boot

Archived from groups: microsoft.public.windowsxp.basics (More info?)

I have 2 HD and the computer boots just fine. I take the secondary drive off
and it will not boot. XP is booting off the Primary. XP is loaded on both
drives, don't ask why, I don't know. The drive is good, the BOIS is good, I
cleaned up the boot sector and recopy the 2 loading files. I made a boot
disk which won't work, the CD won't load, the CD is good. Everything works
with the two hard drive and when I pull the secondary drive off then nothing
works. I have been at this for 3 days. I tested the HD and it's ok. I must
be missing a file but can't figure out what it might be. The BIOS,
motherboard, are even the HD might be bad, but the computer works just find
with both hard drives. This is driving my crazy. I feel stupid, being an
x-computer and network tech for over 10 years. When I do find out what is
wrong, I will really feel stupid. My next step is to take the hard drive and
put it on another computer and see what happens. Any ideas will be
appreciated.
