Windows is unable to find a system with one disk

I am trying to install Vista Home Premium x64 bit on a single hard disk.
It ran through okay once, but once it had to restart for the
installation process, it started all over, and wouldn't get past the
partitioning process. When selecting a drive I get the error:"his
computer's hardware may not support booting to this disk. Ensure the
disk's
controller is enabled in the BIOS menu." and when I click Next it says
Windows is unable to find a 'system' (http://www.vistax64.com/#)
volume that meets its criteria for installation. I've read that this
problem only occurs with 2 hard drives. Any help would be greatly
appreciated. Thanks in advance.
