I know I’ve seen you around, so it kind of surprises me that I have to point this out/ But
That is for kernel 6.3 which has been EOL since July, which leads me to believe you haven’t kept you system up to date or this wouldn’t have happened. And that means you’ve been a bad, naughty boy.
You’d need to upgrade your kernel to a supported version, and try again…
mhwd-kernel --listinstalled ✔ 38s
Currently running: 6.1.51-1-MANJARO (linux61)
The following kernels are installed in your system:
* linux61
* linux65
Manjaro’s GRUB needs to be in control, so you will have to reinstall GRUB, rather than just update its configuration. However, given that you state…
… it is quite possible that you’ve got one distribution installed in native UEFI mode and the other one in legacy BIOS emulation mode (also known as CSM, “Compatibility Support Module”).
Either way, it wouldn’t hurt to try… From within Manjaro, issue the following commands…
In this day and age, I would completely disable CSM altogether. But considering that your system most likely has a mix of installations, it’s too late for that now.
Yeah, the Debian drive was there before I added the second drive and installed Manjaro.
I think, though not sure, the Debian has been updated a couple releases and the original (Debian 10?) did support EFI. So, it has never changed since it has just been OS updated along the way to Deb12.
Some day I’ll probably just clear the drives and start over.
In any case, I booted to Debian, did a update-grub, it found Manjaro again and now Manjaro boots to 65.
