  1. Hey all! I am pretty new to this kind of Win7 issues, so I hope some of you will be able to help. Story goes...

    After few hours of gaming the computer died. (It happened right after switching keyboards.) Now, on every setup BIOS(?) comes up with list of options (F2 enter BIOS, F11 boot options, F6 Flash etc.). After that a black screen with error message comes up: Missing Operating System.

    I tried rebooting from USB (since I have no disk-drive) and I keep on getting the answer: Error Loading Operating System.

    Any ideas?

    Thx

    All unlikely, but possible - (a) your HDD died. (b) your bios became corrupted (c) your HDD boot sector became corrupted (d) your HDD partition is corrupted.

    Does the drive spin up when you switch on (feel it)?
    Check the bios to see if the HDD is reported correctly and is at the top of the boot order.
    Find a bootable CD - an OS installer, or create Easeus partition manager bootable CD http://www.partition-tool.com/personal.htm and boot from it. What does the HDD look like with Easueus?
