Hello,
I’ve just updated my system and the other operating systems are not detected anymore after reboot.
This never happened before.
After executing update-grub I get this:
[mak@jmak-pc ~]$ sudo update-grub
[sudo] password for mak:
Generating grub configuration file …

Warning: os-prober will not be executed to detect other bootable partitions.
Systems on them will not be added to the GRUB boot configuration.
