Yes, you have all the normal options like first "Upgrade" or "custom" then select partition you want to install. It will overwrite everything in chosen partition so beware and select the correct partition based on exact size.Just curious after the dilemma i went thru last night of getting the ISO to install to a chosen partition,Does the ISO give you the "custom" option after your enter the serial or not?
I got nervous of it overwriting my w7 install when it was wanting serial before partiton choice & had to do a bit of googling to find a solution.
