My computer currently has Fedora, Ubuntu, and Windows installed.
I just updated Ubuntu 12.04, and on restarting, the Fedora entry was gone from GRUB. Ubuntu and Windows remained, though.
I have looked at these threads:
- Fedora login gone after Ubuntu updates on a dual boot
- GRUB's menu.lst deleted after a kernel update
However, I cannot figure out how to mount the drive as suggested. It does not appear in the list on the left side of nautilus as shown in the links above.
I also tried running the following as suggested above:
sudo grub-install /dev/sdX sudo update-grub
But this gave scary errors:
/usr/sbin/grub-setup: warn: Attempting to install GRUB to a partitionless disk or to a partition. This is a BAD idea.. /usr/sbin/grub-setup: warn: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and their use is discouraged.. /usr/sbin/grub-setup: error: will not proceed with blocklists.
The highlighted drive below is where Fedora lives.
Thanks for any help reversing Ubuntu's decision to delete this from GRUB.
