Unknown filesystem error: grub rescue [duplicate]

Possible Duplicate:
Grub rescue - error: unknown filesystem

After using testdisk 6.11, I got the error message: 

Unknown filesystem error: grub rescue

To fix it, I used Boot-Repair, but it took too long - hours! (I had to go to sleep and return (: )

So, is there other way to fix it faster? Thanks!

    Try again with Boot Repair.

    1 - Live CD

    First, you'll need to boot from a Ubuntu Live CD.

    2 - Repair the bootloader

    To restore the Grub bootloader, follow these steps.

    Open a terminal from the Live CD, and run the following commands:

    sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair
boot-repair

    After a few seconds, Boot Repair's main window will open.

    Click on Recommended repair.

    You're done!

    Reboot to test everything out.

    If everything went well, you should be up and running now.
