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.
First, you'll need to boot from a Ubuntu Live CD.
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.
Reboot to test everything out.
If everything went well, you should be up and running now.
