    Yesterday afternoon my computer did one of those lovely updates that happen sometimes. I just left it to it. However when I came back to my computer it had rebooted itself...BUT...had a lovely black screen with the words operating system not found. The computer automatically took itself to safe mode, and appeared to fix the problem, taking it back to a previous point etc.

    However, last night it did the update again, and shock horror I wake up this morning to find the same problem, only now it won't go into safe mode, and all it does atm is cycle through black screen, to a loading bar at the bottom, then a flash of the blue screen of evil evil, then starts that all over again.

    I am not completely useless with computers, but where to start is my problem. I have no restoring CDs etc, they don't appear to be with all the other stuff for the computer so thats an issue i suppose.

    Its a toshiba sat A300-211 i think!

    any advice on what I should do would be lovely!!!
