error: unknown filesystem grub rescue >

error: unknown filesystem
grub rescue >

This is the message I get today. I have Windows 7/8 Mint 14 and Ubuntu 12.10 quadruple boot. I tried using supergrub 2 disk 2.00 and Rescatux SG2D 0.30.2. The best I could do was to access one of the grub.cfg files with Rescatux and get into Windows. I have all partitions backed up to external hard drive using Acronis 11 boot disk. Is there a simple way to fix grub?

Please post the actual grub.cfg file and the output of
fdisk -l /dev/sda
when typed in a terminal on Rescatux.
What you have here is not enough information.

Also, try to recall anything out of the ordinary you did before this happened: did you reinstall your bootloader, tweak some settings you usually leave alone?

Thanks for the reply. I used Grub Repair Tool unsuccessfully. I then deleted the partitions and reinstalled Ubuntu. FYI. I did try Windows recovery at one point but did not do anything after getting to the Windows Recovery menu.
