Error booting system from Vista Home Basic 64-bit DVD

Hi!

I currently have Vista Basic Home 32bit installed on my PC. I have the Vista
Home Basic 64bit Full DVD and I would like to upgrade. I know that I would
need to do a clean install but I am having trouble booting from the DVD.

I have set my BIOS to boot from the DVD but I get the below message when it
tries to read the DVD:

File: /Boot/BCD
Status: 0xc000000e
Info: An error occured while attempting to read the boot configuration data.

Any ideas on what the problem is? My motherboard and cpu are new and 64bit
compatible.
