    Question- upgrading win7HP/win8 preview dual boot to win7/win8 pro


    I currently have Win7 & Win8 preview in separate partitions on the same machine. I am trying to figure out the best way to install win8 pro on my system and keep my current dual boot setup with Win 7 intact and stay legal.

    So....I have a 3 licence family pack of windows 7 of which I have used only 1 licence. Is there some way I can use one of the remaining win7 licences to upgrade win8pro over top of the Win8 preview and keep my current dual boot win7/win8 setup(legally) and without messing up my current Win7 installation (or Win 8 preview installation for that matter)? Is there any advantage in getting the OEM version instead?

    If I understand it correctly; Anyone dual booting a legit version of Window Vista, XP or Win7 and Win8 RP can use the upgrade version of Win8 to do a clean install over the Win8 RP version.

    You could upgrade the Windows 8 RP install.

    Well OK then I guess I'll go ahead and take the plunge, there doesn't seem to be any reason to delay. Thanks for the reply

    Just to help clarify.


    Yes, you could upgrade from the "Windows 8 Release Preview" with the upgrade copy of Windows 8 since you can do a clean or ugrade install with the upgrade copy of Windows 8. You might as well do a clean install though since nothing from the "Windows 8 Release Preview" will be kept other than in the Windows.old folder.

    However, you can only run the "Windows 8 Upgrade Assistant" from within the XP SP3, Vista, or Windows 7 that you are upgrading from to be able to purchase and download the Windows 8 ISO first.

    Plus, you need to follow the EULA and not have the qualifying OS (XP SP3, Vista, or Windows 7) installed while the upgrade Windows 8 is installed. "Windows 8 Release Preview" is not a qualifying OS for the upgrade.


    To comply with the EULA and be legal:

    No qualifying OS to upgrade from = need to buy retail "system builder" copy of Windows 8

    Want to keep both qualifying OS and Windows 8 installed = need to buy retail "system builder" copy of Windows 8

    Want to replace your qualifying OS with Windows 8 = you can use "Windows 8 Upgrade Assistant" to purchase a upgrade copy of Windows 8

    hmmm so if someone wants to keep win7 and win8 on same machine they "need" to buy retail system builder. How about if they have more than one Win 7 licence, can one be "used up" for the upgrade & the other one installed on the same machine?

    Yes.

    You can apply the upgrade to any XP SP3, Vista, or Windows 7 key you already own.
