b0 error on the Vista HD

[mdg]

I have 2 hard disks -- one with Vista and the other where I've been trying to install Leopard.

 

I've tried to get EFI working on the Leopard drive and think I somehow screwed up my Vista HD.

 

I get a b0 error when I boot the Vista HD.

 

I ran the Vista Install DVD, tried to repair, and it said there were no problems found.

 

I also have Acronis and when I booted into it, it shows the Vista HD as being marked active.

 

Anyone know how I can fix this or am I hosed...and need to reinstall Vista/lose all my data?

 

Thanks in advance!
