Warning: os-prober will not be executed to detect other bootable partitions

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 …

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:

Thank’s a lot!!! Worked well!
