Will a Vista Ultimate disc upgrade overwrite the 7 RC

I ordered a Vista Ultimate Upgrade disc to get rid of the Windows 7 RC 32-bit. Since 7 is newer, they say it won't work, but I've heard from two sources that booting from BIOS would overwrite 7. Is this true? I don't care if it cleans my HD, I already backed up.

I think you will need a vista or xp install disc to make it work. Not sure about installing from within win 7 rc to upgrade to a vista ultimate. Good luck to you.
