I tried a lot of guides and walkthrough I found on the net, but my problem still persist:
I installed the UBUNTU 14.04 LTS release, and installed side by side my Windows Installation.
When I finish the installation, I reboot the computer and grub goes in rescue mode telling me "error: unknown filesystem". I already restarted the computer e tried to repair by boot-repair, but I still have the same issue.
However I think the GRUB doesn't go on stage 2 because it try to read the partition and give the error message.
- EDIT: Still no answers???
