OK, so basically it "blew up" because it didn't have enough HDD Space to "preserve" the PREVIOUS Windows Installation in case you want to "Uninstall The Upgrade", correct? If so, you are aware that you now have no means to revert to the Windows7, right? No no NOT my actual hard disk. My backup drive incase I wanted to backup all my files I got currently. I got no space available on my portable to back that up. I have lost the pervious windows 7 install though yeah
