[SOLVED] Dual booting arch with mint, grub not finding arch | Arch Linux Community | Page 1

Can't get grub to recognize arch

On mint I did the following:
Made a 500gb free space on my SSD trough resizing partitions.

Using arch-install script I did:

"manually" made a new btrfs FS with all the recommended sub volumes except @.snapshots, as I want to use timeshift

gave the pre-existing boot partition of mint (grub) the mount point /boot

Did everything else according to the recommended settings

Everything installed successfully, but grub can't seem to find arch, I'm only able to boot into mint

Running sudo update-grub doesn't add a boot entry for arch
running sudo os-prober gives no output

#

When I don't mount mint's boot partition as /boot I get a second install of grub from which I'm able to boot arch, but that is not able to see mint, neither is mint's grub able to see arch in that constellation

#

I don't want to be stuck choosing what os to boot to in the bios

vestal zinc I don't know how and why, but I can now boot into arch at least.... I did everyt...

how did you install arch?

vestal zinc Apr 16, 2025, 9:30 PM

#

arch-install script

#

Burned iso on a known good USB with whatever utility mint has for it

#

Trying to to see if I can get into mint still

#

....and I can't get into mint

#

After activating os-prober in grub config and it saying in the terminal that it added an entry for mint.... It didn't

vestal zinc Apr 16, 2025, 9:39 PM

#

Lemme see....

Sorry, but I'll need to continue this tomorrow
It just passed midnight over here, at least I can access mint if needed trough a boot override in my bios for now

#

@vestal zinc try a different theme

vestal zinc Apr 17, 2025, 4:47 PM

#

agile sorrel <@252538050804973568> try a different theme

i fixed it...

#

and i feel stupid

agile sorrel Apr 17, 2025, 4:47 PM

#

@vestal zinc say how you fixed it

vestal zinc Apr 17, 2025, 4:48 PM

#

spot the difference between the two commands:
sudo grub-mkconfig -o /boot/grub.cfg
sudo grub-mkconfig -o /boot/grub/grub.cfg

#

i basically pushed the updated grub.cfg into the parent directory

#

fml

#

first comand is waht i kept doing, second line is correct thing i shouldve been doing

#

...doesnt explain why the grub that mint installed still doesnt see arch, as mint has a script that requires no inputs to update grub with os-prober enabled by default

agile sorrel Apr 17, 2025, 4:51 PM

#

... solved
