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 …

Systems on them will not be added to the GRUB boot configuration.

os-prober has been disabled by default, you need to uncomment/add

GRUB_DISABLE_OS_PROBER=false

to /etc/default/grub and run sudo update-grub.

Thanks. Now, it works.

It worked with me as well! Thank you!

I wonder why such an option was set as true by default though.

Thank you!
recently updated to 5.10.19-1-MANJARO and could not figure out why update-grub could not identify the Windows Boot Manager…
This did it for me :+1:
