The PSU in my main (normal) computer exploded recently quite spectacularly with a flash, bang and a puff of smoke so I thought I would swap the drive into the spare computer while I sorted things out. It was then that I discovered that although the spare board had SATA connections it wouldn't boot a SATA drive. With just the SATA drive connected I got a "No bootable drives" message. It will, however, boot an IDE drive.
I'm sure this is a silly suggestion, but will your "main" PC boot using the PSU from the "spare" PC?
