Vista installation error - bootmgr is missing

I am trying to install Vista Ultimate x64 onto a new Sata hard drive, it is
the only hard drive in the system. During installation, no drives are found
so I load the sata controller driver for the motherboard (Gigabyte
MA790FX-DS5). Vista see's the drive at this point and I can select and
install. The initial portion of the installation runs fine until the first
reboot then I get the bootmgr is missing press ctrl-alt-delete.



I have tried just about everything on this to get this to boot. I have
adjusted BIOS settings to Native IDE, Legacy IDE, RAID, and AHCI. I have
tried plugging the drive into different controllers, tried different drives
(all sata), set boot disk priority to the hard disk etc. Nothing works. If
I go into recovery console from the Vista disk, the system sees no OS
installed so no recovery options work. I have also tried running diskpart
here and clean on the disk before the install with no luck. When browsing
for the driver on subsequent installations, I can see the hard drive and the
windows setup files installed on the disk, so files were written to the
drive, it just doesn't boot. I have been trying everything i can think of on
this and get no where. I have also tried going back to x32 and get the same
results.



I did have Vista x32 running on a different drive in this system but that
installation was done on a different motherboard. Since upgrading the
motherboard, the system was unstable and I have been trying to reinstall ever
since.
