you could also try doing the boot cycle via your BIOS. some bios will allow you to set IDE1 IDE2, etc.. as first boot.
the bios i have at the house will alow me to set to the specific device, not just IDE, sATA, CD, Floppy.
so i could have 4 different HDs in my system and tell it to boot off of HD3 if i wanted.
you might want to check your BIOS for something like that. this works great if you have 2 different types of HDs like sATA, IDE, or SCSI and IDE as more BIOS will alow that configuration over what i have on my ASUS board.
