    Windows 7 upgrade install on Win7/Vista dual boot


    Well i am currently running Vista Home Premium sp2 and Windows 7 Ultimate (build 7100) in a dual boot config for about 2-3months and loving it. I was wondering if i could upgrade my Win7 install to RTM without affecting my Vista install? Do you get a choice which OS you want to upgrade or does it go by what OS you load the upgrade disc from?

    You can upgrade, but you will need to repair your MBR with BartPE or a similar program.

    By MBR you mean Master Boot Record? Can i not just use the repair install feature on either vista or win7 disc to fix it? I duno im being noobish now, just thought i would check here first before i tried. So it can be upgraded but it will cause a problem?

    No, because as far as W7 knows, there is nothing to repair..
