After running sudo pacman -Syu my Laptop doesn't boot anymore, and in BIOS options I can only select boot to uefi, please help.

#

What do you mean by BIOS options?

#

Do you mean your bootloader?

Do you have a live USB for EOS or something similar?

high temple Mar 12, 2023, 4:20 PM

#

Maybe

#

Wait

#

Yes, I do

carmine radish Mar 12, 2023, 4:21 PM

#

Alright, boot into that and get to a terminal

high temple Mar 12, 2023, 4:23 PM

#

Did that

carmine radish Mar 12, 2023, 4:23 PM

#

#

mount nvme0n1p2 to /mnt, chroot in, and run mount -a to mount the EFI partition

high temple Mar 12, 2023, 4:27 PM

#

Is this ok too?

carmine radish Mar 12, 2023, 4:28 PM

#

oh yeah BTRFS

#

you'll probably want to use mount instead of the file manager to mount it

#

also, only do mount -a after you chroot in

high temple Mar 12, 2023, 4:30 PM

#

chroot?

carmine radish Mar 12, 2023, 4:30 PM

#

use mount /dev/nvme0n1p2 -o subvol=@ /mnt, then arch-chroot /mnt, and finally mount -a

high temple Mar 12, 2023, 4:38 PM

#

What now?

carmine radish Mar 12, 2023, 4:45 PM

#

Can you show the entry in /boot/loader/entries/?

high temple Mar 12, 2023, 4:47 PM

#

I don't think that is supposed to be empty

#

carmine radish Can you show the entry in `/boot/loader/entries/`?

From within chroot

high temple Mar 12, 2023, 4:48 PM

#

Whats the command for it?

carmine radish Mar 12, 2023, 4:48 PM

#

First run ls /boot/loader/entries/ to figure out what the name is

#

Then use a terminal text editor like nano or vim to edit it

high temple Mar 12, 2023, 4:49 PM

#

No sich file or directory

#

Such

carmine radish Mar 12, 2023, 4:49 PM

#

Try /boot/efi/loader/entries/

#

Are you still there?

carmine radish Mar 12, 2023, 5:05 PM

#

Sorry

#

Well it seems you're lacking a kernel

#

Can you show me the file in /efi/loader/entries/?

high temple Mar 12, 2023, 5:06 PM

#

carmine radish Sorry

You don't have to be, just asked.

high temple Mar 12, 2023, 5:07 PM

#

carmine radish Mar 12, 2023, 5:10 PM

#

hm

#

First you'll need to reinstall a kernel, pacman -S linux should work for that

high temple Mar 12, 2023, 5:13 PM

#

In root?

#

Ok

#

carmine radish Mar 12, 2023, 5:17 PM

#

Oh, something must have messed up the update

#

Delete that file and run pacman -Syu

high temple Mar 12, 2023, 5:18 PM

#

Ran pacman -S linux first

#

When running pacman -Syu

carmine radish Mar 12, 2023, 5:26 PM

#

You might need to exit and re-enter chroot

high temple Mar 12, 2023, 5:28 PM

#

Yea

#

rn_image_picker_lib_temp_d5d388cf-1b1d-4411-b67e-4fce7e1947eb.jpg

#

#

carmine radish Mar 12, 2023, 5:32 PM

#

Is /boot still only have one file?

high temple Mar 12, 2023, 5:33 PM

#

Yes

#

Should I run pacman -S linux again

#

Btw I ran pacman -S linux in loader/entries

#

Alright that looks good

#

You can exit out of chroot and reboot

high temple Mar 12, 2023, 5:40 PM
