Ned, if it's anything like my experience as soon as you re-enable the second
hard drive vista refuses to boot again. Doing a startup repair simply puts
the boot files on the second hard drive rather than the first. In the end i
simply reformatted both drives re-installed XP, created another partition
and then installed Vista. The boot files on the second hard drive, by the
way, was due to the BIOS, apparently. As no new BIOS updates were available
fro my machine (which is 2 years old) the above scenario was the only
I originally dual booted and all i wanted to do was wipe the drive and
install Vista on drive 0. Install went fine, rebooted machine and got a
'cannot find operating system' message. Took out the second hard drive and
did a startup repair, Vista worked perfect. Installed the second hard drive
again and rebooted 'operating system not found' message again. Did a startup
repair and vista created a 10GB partition on the second hard drive and
installed the boot files there. It was actually a nightmare to finally get
things working how i wanted them to - unfortunately that meant re-installing
xp and vista on a dual boot system again. The alternative, of course, would
have been to buy a larger hard drive (my machine runs 2 x 80GB drives).
