Dual Boot issue - Vista 64bit and XP

I got a problem.
I had windows XP installed on a Raid (over 2 Raptors) and I installed Vista
64bit on a new SATA harddrive. Vista could not see the raid correctly till I
assigned some unsigned drivers to it. Now it can see both my old window and
the new one.

I want to be able to boot into my old XP also, and I used bcd to add a
legacy H: (which is the drive letter of my XP shown in vista) but when I try
to go into it in the boot screen, it just restarts the PC.

Also, I noticed I cant boot without the CD, I get a BOOTMGR missing message.

Any Ideas?
