Laptop with windows 7 crashed. This file might be corrupt

Hello,
When i start my laptop which has windows 7 I get this message "This file might be corrupt. The header checksum does not match the computed checksum". What can I do to correct this problem? Help!

It showes up before windows even start. The only thing that does work is f12 where i can select 3 different boot devices:
Internal Hdd: Sandisk ssd u100 16gb
SATA HDD
Network Boot:Atheros boot agent

None of them is working nor can i do anything els with it.

This occurred last night or this morning.
The laptop did not move nor did it does nothing. I shut it off like normal and when i tryed start it again ei get the text.

ps. It wont let me boot it up with either the win7 disk or the win8 recovory disk

Edit. I can now open bios but not advanced bios.

  1. Best answer
    It sounds like your bios has eaten itself. Is there some kind of built in bios flash utility (like Gigabytes QFlash) on your laptop? If there is I suggest you go to your laptop manufacturers website and see if there is a download for the bios and try flashing it.

    Otherwise, you may have to send it in for repair...
  2. Reset everything to defaults in the BIOS
  3. I was hoping that i did not have to send it in for repair because i am on holiday right now and i wont get home until a few more months. And without my laptop that long is going to be hard. I have the Y500 lenovo laptop if that helps.

    I also got in to the windows 8 recovery disk thingi with my recovery CD. I tried Fixing it with that but i got an error with every single troubleshoot. The one where i tryed installing win8 with said i was missing a necessary unit partition.

    Thanks for the fast answer.

    I also tryed reset everything to default both with win8 settings and other OS settings
