Windows 7: Will a Vista Ultimate disc upgrade overwrite the 7 RC

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.

I lost my Vista box and disc, can I still use upgrade?
I have a valid legal copy of Vista Home Basic installed on my computer. I have lost the install disc and box. I would like to do a clean install of 7 home premium on a new empty HD (a different HD than the Vista install) on the same computer. Is this possible with the upgrade version?

Does 7 upgrade overwrite/remove Vista
I just want to make sure that installing 7 as an upgrade 'over' Vista removes all of Vista's operating system, particularly the registry. Is this a correct assumption? I've got some registry entries for magicjack that I can't remove with Regedit due to permission problems and since my "7 upgrade"...
