Windows dual boot "BOOTMGR NOT FOUND"

[rhoadsfan]

I have a Unibeast'd Lion install on my primary Hard drive, a second Mac formatted hard drive for data, and a third hard drive that I'm trying to install Windows on. I can get it to install, but then when I try to boot from the drive from the Chimera selection screen, it says "BOOTMGR NOT FOUND". Is this an issue with Chimera, or am I just not going through the proper process for dual booting? If I'm not, could someone help walk me through how to get Windows to boot with my current setup?

Make sure, win is on a primary boot partition...

I did it in a different order:
installed win first on my 1st disk and made sure, that it is booting correctly, then I installed MAX OS X on the 2nd drive and changed boot order from 1st to 2nd disk...
