#1 Re: Installation » GRUB Grief » 2023-02-25 13:19:42
Ubuntu owns the boot management for your system and by default won't allow any other OS's to boot. Here's a quick and simple step-by-step procedure to get Ubuntu to add your Devuan (and any other GNU/Linux partitions) to grub: https://www.omgubuntu.co.uk/2021/12/gru … istros-fix
Before finishing those steps, I would make sure that the os-prober package is installed on your Ubuntu: 'apt policy os-prober'
Thanks for that.
I'm still running Ubuntu 20.04 and am avoiding 22.04 due to various issues with that release.
I tried disconnecting my 1st HDD and reinstalling Devuan. With the only the 2nd HDD connected, Devuan starts normally. Reconnecting the 1st HDD causes the system to boot Ubuntu as before, but selecting the 2nd HDD from the BIOS boot menu starts Devuan normally.
This is not ideal and I would really like to have a proper GRUB menu at start-up, but I can live with this for now.
I moved to Ubuntu to escape the insecure, bloated lethargy of Windows, but I now find similar issues with Ubuntu since the shift to systemd and snaps.
I'm looking hopefully at Devuan as a return to a fast, secure, reliable OS.

I tried installing [devuan_chimaera_4.0.0_amd64_desktop] on a new HDD in my PC, selecting the "guided encrypted LVM" option.
I want to have the option to boot into different OSs and am trying to get a GRUB menu at start-up.
The installation goes OK until I get to the GRUB installation: I chose to install GRUB to the new HDD because my existing (Ubuntu) OS was not detected and I didn't want to risk losing the ability to boot into that.
Things have become a lot more complicated since the last time I set up a multi-boot system with GBUB, which only required editing the GRUB menu file!
Now, things are all the more complicated by using encrypted volumes, which I suspect is why the GRUB installer won't recognise the OS on my 1st HDD?
Even though the installation appears to complete successfully, there is no GRUB menu and my system boots Ubuntu as before. Choosing to start the new HDD from the BIOS boot menu produces a "Welcome to GRUB!" message and a "grub_rescue" prompt - at which point I'm stuck.
I suspect that I need to find a way of either unlocking my existing encrypted disk first, to allow the GRUB installer to see it, or editing GRUB settings to recognise encrypted disks?
