"Inaccessible Boot Device"

When I try to turn on my computer, Windows attempts to boot, but is then interrupted by a blue screen with a stop error that says "STOP: 0x0000007B  (0x81868a10, 0xC0000006, 0x00000000, 0x00000000) INACCESSIBLE_BOOT_DEVICE".   Then it says to check for viruses, but I can't because it won't boot up.    I've tried using F8 start up screen, but I tried a few things nothing will work.  It keeps going back to the blue screen. Then I tried looking at a Windows help page that didn't help, but it did say that if someone tried to help me these numbers might be helpful :"0x4, 0, 0, 0".  Can anyone help?

Do you have access to a CD burner and Nero and a computer that you can temporarily install a few small applications on?

If it looks too complicated, ask one of us to help, or take it to a computer repair shop.

Also if you are running XP or 2000, you can run the Repair from the install disk and that should correct some of those errors.  Here is a link on running the repair function if you don't know how: http://www.michaelstevenstech.com/XPrepairinstall.htm
