My Grub 2.06 won't detect other operating systems on UEFI.


Grub 2.06 in Slackware current on my computer won't automatically detect other operating systems. When I entered "grub-mkconfig -o /boot/grub/grub.cfg" the terminal read
Code:
Warning: os-prober will not be executed to detect other bootable partitions.
Systems on them will not be added to the GRUB boot configuration.
Check GRUB_DISABLE_OS_PROBER documentation entry.
Grub 2.04 detected the other operating systems fine. I also have Ubuntu MATE 20.04 and Windows 10,

Hey, os-prober is no longer enabled by default.

nano /etc/default/grub

then add

Code:
GRUB_DISABLE_OS_PROBER=false
or uncomment it if it's there.

Then you can grub-mkconfig -o /boot/grub/grub.cfg
