I am in the market for some advice. I am considering updating my Vista SP1 to Windows 7 RC. My machine is a dual boot and I also have Linux Mint (ubuntu) installed. When it boots, the grub boot loader comes up first and I have to choose Vista from a list to boot it. Now, if I upgrade directly to rc7, is this boot loader going to cause issues? Thanks! Another semi-related question. For those that run the rc, when the gold comes out, is there any speculation on how a person transitions to that? Or will it just involve getting an activation key and the rc being updated via the auto updates?
