Number one rule - in setting up dual boot always install the older OS
(Server) first then Vista. To try Vista repair as Rick suggested:
Boot the Server OS - insert Vista DVD - shut down and restarrt the computer
to boot from the Vista DVD. If computer set to boot from CD/DVD drive a
message will pop up about booting from the drive - hit any key.
If it does not boot from the drive you must set boot order in the BIOS so
that tthe CD/DVD drive is the first in the boot order.
Vista will offeroptions to "Instal..." or "Repair..." - select repair and
follow the prompts - if repair not successful on one first attempt - try a
second time.
