Description Mirko Predosin 2019-05-07 02:52:32 UTC

Description of problem:

I have dual boot system with Fedora on /dev/sda and Windows 7 on /dev/sdb.  After the upgrade from F29-F30, all of the Fedora entries were missing.

It turns out that grub2-mkconfig was failing due to a change in /etc/default/grub.

Changing the GRUB_ENABLE_BLSCFG entry resolved the issue.

GRUB_ENABLE_BLSCFG=true
to
GRUB_ENABLE_BLSCFG=false

This seems relevant and shows what motivated the change in /etc/default/grub that broke my system.

This is the article that I came across explaining the fix.
