Reformat?
Hi, I just upgraded from Win 7 RC (Ultimate) to Win 7 Home Premium on a machine that originally came with Vista. I thought I had done a clean install, but I noticed there is only 16GB free on 70 GB C:drive. (D: drive is 70 GB also, and mostly free). Can that be right? A clean install shouldn't use 54GB should it? Thing is, I can't figure out where all that data is on C:, Windows.old file is only 1.5GB. and I see no trace of any other old files. I guess I must have missed a step and not reformated the HD. I think my mistake was just inserting the disk while the machine was running instead of booting up from disk (?).
1. Can I go back and reinstall, except this time reformat?
2. Do I really need a big empty 70GB D:drive partition, or should I just make it all one big C:drive?
Problem is, it's running PERFECT, and I don't want to screw that up!.......OK, just inserted disk and rebooted, it did not enter setup, just went to my normal W7 Home Premium sign in screen. Maybe I need to change boot order in Bios? I do have an external HD (I disconnected it before install) I could save my Windows.old folder to, if I wanted to keep that data.
