|Forgive, but the usual questions come to mind:|
1. Are you booting to the DVD drive in the BIOS setup?
2. Is the Vista disc scratched or somehow unreadable? (try it in another machine)
3. Are you attempting this from within Windows? (Windows will not commit "suicide" by trying to do something like formatting the drive it resides on from within itself)
