    It seems as though most local stores only carry the Windows 7 Upgrade disc and not the full version for a clean install without a previous version of Windows.

    Can you use an "upgrade" disc to install on Bootcamp?

    I remember the older previous versions you could trick Windows in to thinking you had an previous version by ejecting and inserting a older windows install disc.

    Nope, it has to be a install DVD, not upgrade.

    celticpride678 is correct that to comply with all of the licenses you need a full retail copy of Windows 7, not OEM, not upgrade, to run on your Mac.

    Definitely, your smoothest install and one that fully complies with all of the licenses will be with the recommended full retail license which is not hard to find online (Amazon, NewEgg, TigerDirect, ...)

    However the upgrade installer just doesn't check so you can install it on "bare metal" http://www.winsupersite.com/win7/clean_install_upgrade_media.asp and OEM "works" too even though its use on a Mac is outside the license agreements.

    You can do it by choosing to activate after installation, but it won't accept your product key. There is a registry change you can make to get it to stop caring and it'll be fine from then on.

    I had to do it when I bought a new hard drive to replace one that had Win7 over Vista. Microsoft were extremely defensive, and refused to help at all. They went as far as claiming I'd hacked my original install.

    Well, not to threadjack or anything, but what I did on my PC was installed an old copy of Vista first, then validated the Win 7 install based on that. Once the upgrade disc had confirmed that there was a previous installation of Windows on that partition, I just let it do a complete clean install.

    Seeing as the way that OSX handles Windows differently, does anyone know if this will work the same way on a Mac?

    If you don't already have a full version of a previous Windows version that you WILL BE RETIRING, then this is not legal.

    Yes, there are technical workarounds, such as the registry-key hack. However, that requires that you go through the install twice.

    Assuming you do have an earlier version that you won't be needing, the easiest way is to temporarily attach a disk drive containing that system to your computer during the install. You could do this using a USB drive (or drive case that accepts your old disk) or (for the brave who know what they are doing, and assuming a compatible disk drive) a Y-cable.

    Windows 7 upgrade won't install just using the old version's DVD as previous Windows versions would. It requires an installed and activated installation. But it does NOT have to install "over" the previous version - it can install into another partition or drive.

    For my own install on my Macbook (VMWare - not Bootcamp) I just temporarily attached my Windows XP virtual disk to the new VM. Worked like a charm.

    I then copied the VM to my Linux system and activated it there as well. (I got the 3-user upgrade.)

    I made a clean install of Win 7 Ultimate, with an upgrade key in Bootcamp, using "method #2" from the same link posted earlier in this thread:
    http://www.winsupersite.com/win7/clean_install_upgrade_media.asp

    I didn't realise that the student/faculty key I had was a upgrade key until it wasn't accepted during the install. I completed the install without the key, planning to get another, non-upgrade one from the school admin (you have a 30 days trial, before needing the key). Of course he didn't have any non-upgrade keys available for Win 7 Ultimate, only for the Enterprise edition (the school PC's have Enterprise while the students/staff are issued Ultimate). Instead he gave me a Vista CD and key and told me to install Vista first, then upgrade.

    I didn't really want to do two more installs so I searched and found the link posted earlier. I followed the few easy steps in "method #2", typed in the upgrade-key, and everything was OK. Really no trouble at all. And since I had the Vista CD with a valid full-version key in my left hand, while typing in the upgrade key with my right hand, I really didn't feel guilty of doing anything illegal, either. ;-)
