When I boot my computer I get this:

error: no such device: 6ae62c89-5573-4c83-b4b8-9aa3722bd1f8.
error: unknown filesystem.
Entering rescue mode...
grub rescue>


I installed Fedora 26 and then Windows 10 on another partition. After then installation of Windows, the system was booting directly on Windows without the option of Fedora.

I used the same Fedora live CD to run a virtual environment and run the following commands on a terminal:

fdisk -l
grub2-install /dev/sda
grub2-mkconfig -o /boot/grub2/grub.cfg

Any idea how to fix it?

  • The order I typically use is "grub-mkconfig", then "update-grub", then "grub-install /dev/disk".. Also verify your UUIDs match in grub.cfg vs blkid. – Damon Aug 25 '17 at 7:56
  • In the future, I think the general consensus is install windows first; ALWAYS. Windows kills anything it can, so if you install it first, it (windows) cannot "kill" anything. Linux is happy to play with other OS's. – Damon Aug 25 '17 at 7:59
  • This answer superuser.com/questions/359417/… might be helpful, although only loosely related to your Q's. – Damon Aug 25 '17 at 8:00
