[Solved] Bookworm grub will not boot proper to second OS

#1 Post by Augie77 »

Debian 12 - Bookworm : My grub has gotten, well...grubby. I have a dual boot with Mint on the second partition and Bookworm on the third partition. When in Debian and rebooting for the grub to go to Mint, I have the emerald Debian grub theme presented and I select Mint and I get the Emerald Screen of Death with the warning - "error: out of memory. Press any key to continue...", and the system locks up and I have to power off/on boot the box. When I am in Mint, I have the vanilla black/white Mint grub and I can select either Mint or Debian and have a successfull boot to either OS.

In the BIOS I have Fast Boot, Secure Boot, and Platform Trust Tech all Disabled. When I have the boot priorities set as Debian first then I get the Debian grub, and with Mint as first I get the Mint grub. Booting to Mint only fails with Debian set as first boot priority, the emerald grub is presented and i select Mint. This issue was present when I had Debian KDE installed and is now present with Debian XFCE installed and was there from the first initial boot after installation.

I have ran

Code: Select all

 os-prober and update-grub
and both completed successfully. I have hunted around the site for this specific problem and did not find a resolution; below is some more information, useful and maybe not useful. What steps do I need to take to fix the emerald grub?

Re: Bookworm grub not boot proper to second OS

#2 Post by lewulff »

Can you provide the contents of /etc/default/grub for both distros (not sure if it is in the same place in Mint)

Also, do you have efibootmgr installed (it is in the Debian bookworm repository, should also be available Mint)? If so can you run it and provide the output?

Re: Bookworm grub not boot proper to second OS

#3 Post by Augie77 »

Hello Lee, here are the requested files. I have also added the grub.cfg file from Mint Virginia and Bookworm. I did notice the Bookworm grub.cfg when viewed in Thunar, the icon for the file had an small 'x' on it and the file type was 'unknown'. Perhaps that is significant?

the Bookworm requests first...

Re: Bookworm grub not boot proper to second OS

#5 Post by pbear »

Don't see anything amiss in what you've posted so far. Please report the output of apt list --installed grub* in both systems. sudo not needed, as it's merely a query.
Also, please post your system information. Install inxi: sudo apt install inxi. Then run inxi -Fxxz

To confirm the obvious, yes, Debian generally boots other systems added to Grub by os-prober.

Re: Bookworm grub not boot proper to second OS

I took another look at the list for installed grub and ran this command, I think this may be what you were looking for. I had missed the ' * ' on the first attempt. :oops:

Any particular reason you're running the 6.5 kernel in Mint? If so, maybe upgrading the kernel in Debian will help with the Grub problem. Long shot, though, if there wasn't a particular reason.

Not that I recall, other than it was available in Update Manager so I selected it. I can update Bookworm, which image should I select? Also, I did notice the Bookworm grub.cfg file when viewed in Thunar the icon for the file had an small 'x' on it and the file type was 'unknown'. Is that a problem?

Synaptic only shows available the currently installed kernel, plus earlier versions. I then entered the backports in the repository for Synaptic and still do not see a later release.

I am searching Synaptic for 'linux-image' and 'linux-header'.

Re: Bookworm grub not boot proper to second OS

#11 Post by Augie77 »

OK, well I have it now. I needed to add
deb http://deb.debian.org/debian bookworm-backports main
to etc/apt/sources.list.

Those pesky Debian instructions do come in handy. :lol:
I removed the previous two entries for backports from the repository Other Software tab as they caused an error during the terminal update.

I see there is a 6.5.0 and a 6.6.13 available, any suggestions on which one to select? I intend to use Debian as my main OS so I can always boot to it initially and if I ever need to use Mint, I can boot to BIOS and select Mint as the first boot. Still, I would rather find out the issue here and fix it.

When all else fails, and you can no longer blame the OS, or the User...you then look at the BIOS. :lol:

Looking back on the fail error, it was always a memory error, as in it was out of memory. I do not know which of the two below settings fixed the grub boot issue from Debian to Mint, but I suspect it was the Above 4G Decoding, I changed it from Enable to Disable.


Edit: I can't stand a mystery and so not knowing which option was the culprit, I tested further. It seems the memory allocation/address for the onboard Intel graphics processor was the culprit. I changed the Shared Memory for the onboard graphics from 1024m to Auto. After a handful of restarts I am confident this was the issue. The motherboard is an Asrock H670M Pro RS with firmware 14.01 and the feature option was under Advanced/Chipsets.


My thanks to all, and I hope this will help someone in the future.

Re: [Solved] Bookworm grub will not boot proper to second OS

#13 Post by pbear »

Congratulations, well done. The mystery remains of why Mint could boot both but Debian only itself. OTOH, I'd probably be content to make a note to self about the kernel and move on. My understanding, by the way, is that you want to disable backports except when using. No need to remove from sources.list. Commenting it out (placing a # at the beginning of the line) will be sufficient.

As for the kernel, if the issue comes up again in some other context, I'd install 6.5 to match Mint. And don't delete 6.1 until you're sure 6.5 is working well in Debian.

Sounds like good advice, I only tried backports as I understood that was where to find the later kernels. As it is, Bookworm and my hardware are quite happy on the .iso installed kernel so I will leave it at this kernel version unless, as you mentioned, something goes asunder.

I appreciate the help, many thanks.
