Hi - Can not find the answer to this anywhere, so far . . .

I run Windows 7 and Win8CP in a dual boot setup. I want to "upgrade" to Release Preview
and install it on the same partition where CP now resides. I tried installing while in CP by
opening the Windows Explorer Folder and finding the DVD drive with the .iso and then click
on "Setup". Installing from within Win8CP seems to be right but is it? I'd like to be sure that
it will install to the correct Drive (partition). Guidance, anyone? Thanks!
