This error message pops up and then I'm stuck in a black screen

#

That sounds like there's a typo in your grub.cfg, somehow

#

You can try pressing E on the entry for Arch, and showing us what it shows you

This?

replace the ^ after amd-ucode.img with a space

night dove May 28, 2023, 3:07 PM

#

Not working

carmine thunder May 28, 2023, 3:11 PM

#

are you getting the same error?

night dove May 28, 2023, 3:15 PM

#

Ok I've just noticed something

#

I use grub in my arch install

#

But the fedora uses grub2

#

Can that be the cause?

carmine thunder May 28, 2023, 3:17 PM

#

that's the same thing

night dove May 28, 2023, 3:17 PM

#

Sorry I'm dum

#

One more thing

#

The grub with fedora show the arch

#

But the one with arch doesn't

#

Yea

It's kinda blurry

#

Sorry

#

you probably need to enable os-prober for the arch GRUB

night dove May 28, 2023, 3:25 PM

#

I've done it

#

Wait let me check the config again

#

this is my grub config

📎 grub

carmine thunder you probably need to enable os-prober for the arch GRUB

?

I did this in my arch install

carmine thunder May 28, 2023, 3:34 PM

#

You need to edit /etc/default/grub and uncomment the line at the bottom about os-prober

night dove May 28, 2023, 3:34 PM

#

night dove this is my grub config

Already done

carmine thunder May 28, 2023, 3:34 PM

#

Oh you did, also install the os-prober package

night dove May 28, 2023, 3:35 PM

#

Done

#

Already in both

carmine thunder May 28, 2023, 3:35 PM

#

If you aren't using a shared EFI partition for the two, you'll need to mount Fedora's EFI partition

#

or maybe it's root, depending on where the kernel is

night dove May 28, 2023, 3:36 PM

#

No they have different efi partitions

#

Is that a problem

carmine thunder May 28, 2023, 3:36 PM

#

You might need to mount one of it's partitions for os-prober to find it

#

P1 and p2 are for fedora

#

Rest for arch

carmine thunder May 28, 2023, 3:38 PM

#

try mounting p1 to /mnt, and then running grub-mkconfig again

night dove May 28, 2023, 3:40 PM

#

Ok

#

Do I reboot now?

carmine thunder May 28, 2023, 3:41 PM

#

Did it mention fedora?

night dove May 28, 2023, 3:41 PM

#

Yes

#

Ok fedora booted

#

From arch's grub

night dove May 28, 2023, 3:44 PM

#
