Re: os-prober issue. Not find all distributions on multi boot SSD

First things first

Debian Wiki - Grub:

apt-get install os-prober

Then edit /etc/default/grub and make sure you have a line like

GRUB_DISABLE_OS_PROBER=false

Finally run update-grub2

Hello,

I have actually on SSD SATA installed these distributions: Linux Mint,

Ubuntu Desktop, Kubuntu, Lubuntu, KDE neon, Fyde OS. All actuall version.

Screenshots are from KDE neon.

Command sudo update-grub not work correct for me. It finds only Ubuntu

Desktop, no other distributions.

All screenshots are here

The last distribution you have installed has done grub-install. So sudo

update-grub within this distribution will work.

All sudo update-grub from the other distribution will not have any

impact on the grub menue.

So I suppose the last installed distribution does not find the other ones.

What I would do if I were in this situation: run rescue from Ubuntu and

do a chroot to get in Ubuntu. Then run grub-install and see if the other

distribution were found.

But the problem remains if that works: Only update-grub from last

distribution which did grub-install will have impact. So if you get a

new kernel from updates of one of the other distribution this change

will not get in the grub menue.

I do not know if there is a clean solution for this problem.

My solution for this situation was to have one disk for only one

distribution and having several USB-HDDs to run several different

distributions.
