I am getting the following grub error: attempt to read or write outside of disk 'hd0'.

Is there any way to fix this error? I can't boot into Debian because of this.

Partitions:

SCSI1 (0,0,0) (sda) - 250.1 GB ATA WDC WD2500BEVE-0
    #1 Primary 249.0 GB B ext4
    #5 logical 1.1 GB F swap swap
SCSI3 (0,0,0) (sdb) - 7.8 GB USB Flash Memory
    #1 primary 7.8 BG B fat32

SCSI3 is a USB device to load in some firmware needed for the install of Debian.

    You would at the very least need to provide your grub configuration and partition information to get any valuable answer. – Julie Pelletier May 25 '16 at 17:16
  • @JuliePelletier As I stated, I am new to Linux and everything surrounding this, and as I don't seem to be able to boot into any OS, I don't know how to access this information, though I can add the partition information, so I'll do that – Grey May 25 '16 at 17:22

    Obviously, if you can not boot from this setup, you'll need to boot from a USB key or other device to verify and correct your configuration. – Julie Pelletier May 25 '16 at 17:25

Because you're usign debian, it will be very easy to recover grub, using the installation CD.

Boot the install Debian CD and select Advanced options -> Rescue Mode There you will have options to reinstall grub or to go to a chroot shell, and reinstall grub using:

grub-mkdevicemap  
grub-install /dev/sda  
update-grub
