yea...why are you trying to boot from the slave drive if it has no OS...alight but ne way i ran into the same kinda thing awhile ago what have to go its repair the NTDLR file or reinstall windows...the NTDLR file boots everything i think i think you might just be able to pop in the OS disc and do whatever you want.... i also ran into a problem with another comp and it was with the NTDLR file and it turned out my memory was bad...so yea lol try that
