My laptop has been a little sluggish lately. I don't know why. Then this morning I am sitting around and decide to load a game from an iso. I start up magicdisk and load the image. Nothing good happened. I try close the programme. Nope, not even through system monitor. Then I decide to restart my computer. Usual start-up then at the password screen... it goes blank. I try again. Same thing. Then I give up and start Ubuntu, thank god for dual booting.

Back at home this afternoon I run the weird windows check thing. It says it can't fix anything and there's some unknown change to the system registry that is stopping windows from starting. Then I back everything up and am ready to do a system restore. There are no restore points available....

Either I can use my restore disks, ie erase the last 2+ years of updates and tweaks to Vista or just give up and convert the whole laptop to Ubuntu. What should I do?
