Vista - Business to Ultimate Problem

Hello,

I'm trying to upgrade from Business to Ultimate and am running into a
problem. I downloaded the upgrade file, ran it, and started to upgrade my
Vista install. Only snag while upgrading was a warning saying that a Raid
SCSI controller would be problematic. The thing is, I'm not running raid and
do not have one installed. So I continued to upgrade. The install completed.
It tried booting to windows but failed. I then tried to run it in safe mode
and that failed as well.

I rolled back the Install which brings me here. I don't know what the
problem is. Any help would be great.
