Os-prober grub

General system Newbie

Hi ho diggity,

i got a warning when i updated my eos.

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.

What does that mean and how can i fix this again?
Thank you.

This means that if you have other systems on your drive they will not be detected and added to the Grub boot menu since os-prober will not be run (the Warning text said it much better :wink:).

You could add

GRUB_DISABLE_OS_PROBER=false

to

/etc/default/grub

and regenerate grub.cfg

sudo grub-mkconfig -o /boot/grub/grub.cfg

if you want/need os-prober to run again.

After today s GRUB update I ran into this “issue” for the first time myself (Warning: os-prober will not be executed to detect other bootable partitions) & thought it would be nice to have the solution handy. :wink:
Cheers
