Well, that sucked. I tried booting up my 7 partition the other day, and just toally out of the blue and random, failed start up. Hanging at the "Loading..." screen for Windows. Tried it a few times, and nothing. All that I could do really was reformat and start again. Which I did. No idea what caused it. I am incredibly careful about keeping my PC secure from infections and the like (I have had one in the last year, and that was through no fault of my usual procedures), and the computer was 100% clean two days before hand (at least according to Spybot S&D, Ad-aware and avast!). At least on the plus side, all the old installation is saved to windows.old, meaning I can copy out any files, work, saves etc I want before removing the folder (through Disc Clean Up, I do not suggest just deleting it!). If this is a new addition, then I am very much impressed. Brand spanking new install with the old files saved just incase. What's not to love? I was incredibly annoyed at first, but when I found all my old stuff safe and sound, I have to admit, I was surprised and impressed.
