Can I Do a clean install after an upgrade?

Next Thursday I'll be upgrading from Vista64 to Windows 7. I plan to do an upgrade to test things out. After verifying which applications/utilities work or don't work, I'll be daring and bold and would like to do a clean install.

Will this be possible using the the upgrade disk I will receive on Oct. 22?

It should be. The disc itself contains Windows 7 (the complete OS).

I was curious about this myself. So, how do you verify that you own a legitimate version of Vista to upgrade from? Vista came with my pcs, but I ditched them as soon as the first win7 leaks appeared.

Thanks to all that replied.

Theog;
If I have to re-install Vista64 then I should consider a dual boot. Do you know if this option allows for the clean install after the initial upgrade?

According to the EULA, you're not allowed to use the qualifying OS anymore (the version of Windows you upgraded from). Except if you need to reinstall Windows 7 again in the future.

EDIT - of course you could probably still use Vista so long as you don't use 7. In other words you're not supposed to be using them both. Whether or not a dual boot actually violates the license agreement, I don't know (technically you wouldn't be using them both at the same time, as you'd need to reboot to get to the other OS). It seems like a bit of a gray area.

I want the cleanest possible install so I am going to install to a formatted partition rather than overwrite the upgraded XP/Vista. But, since I don't want XP/Vista after it is upgraded, and the XP/Vista has to be on the first partition to boot and run the upgrade, then I am considering installing the upgrade to a second formatted HDD.

On my laptops, I'm considering copying the XP/VIsta image to an external HDD and setting it to boot, then installing the upgrade to formatted HDD.

Does anyone have any other ideas how to get a formatted upgrade install.

Now you have me thinking. I plan on doing a clean install anyway. Can I have my current OS on one hard drive, install Windows 7 on a second hard drive, then remove the old one and go from there?

I think I'll be re-arming a few times while I consider my options.

Not possible, you either do an upgrade with an upgrape release or to do an OEM I imagine you will need the full release.
