SOLVED

TL;DR - cloned old system from /dev/sda to /dev/nvme0n1 using dd. I can chroot into nvme, but it doesn't boot after going into GRUB.

I have cloned my system from /dev/sda2 (ext4) to /dev/nvme0n1p2 with dd, created empty FAT32 on partition 1 with boot+esp flags. After disconnecting /dev/sda, files were intact and I can chroot into it over live USB.

I did clone GRUB on partition 1, but it would say ERROR: device '/dev/disk/by-partuuid/75***af8' not found. PARTUUID is exactly the same, on live USB it mounts to arch.

I tried reinstalling GRUB, but it would go into GRUB prompt, tried systemd-boot, it show "boot into firmware" (if I recall correctly, only one button and it would go into UEFI setup).

Any suggestions? /boot/efi/EFI exists and files are there.

For GRUB did you generate the config, and for systemd-boot did you make the entry for Arch?

grizzled island For GRUB did you generate the config, and for systemd-boot did you make the entr...

For systemd-boot currently I only did bootctl install and it did create EFI boot entry "Linux Boot Manager", but I don't think it did anything more than that.
GRUB - I had config before, but I did not regenerate it. (Since all UUIDs should've stayed the same)

But I don't know much about EFI...

#

You need to regenerate the grub config

paper salmon Feb 18, 2023, 1:20 PM

#

I'll try reinstalling GRUB again then

reef fox Feb 18, 2023, 1:21 PM

#

You shouldn't need to

#

Just generate a new config

paper salmon Feb 18, 2023, 1:21 PM

#

I deleted the partition with GRUB to install systemd-boot since GRUB wasn't working

reef fox Feb 18, 2023, 1:21 PM

#

Oh okay

#

Your esp is mounted on /boot/efi right?

paper salmon Feb 18, 2023, 1:24 PM

#

Previously when I used GRUB, partition was mounted at /boot.

reef fox Feb 18, 2023, 1:24 PM

#

Okay but you said /boot/efi/EFI exists

#

Which leads me to think it was mounted on /boot/efi

paper salmon Feb 18, 2023, 1:25 PM

#

Currently with systemd-boot it was, sorry for confusion

reef fox Feb 18, 2023, 1:25 PM

#

Probably best if you post your fstab

#

Well I think you also need a new fstab if you migrated from a drive to another

# when it was systemd-boot, it was /boot/efi, currently I'm installing GRUB at /boot so I changed it

#

UUIDs were changed accordingly

reef fox Feb 18, 2023, 1:28 PM

#

Alright

grizzled island Feb 18, 2023, 1:28 PM

#

What's inside of the EFI partition right now?

paper salmon Feb 18, 2023, 1:29 PM

#

Oh, I may had to change /boot/efi UUID yet again after wiping it to install systemd-boot

#

but arch partition UUID is exact the same unchanged from /dev/sda2

paper salmon Feb 18, 2023, 1:29 PM

#

grizzled island What's inside of the EFI partition right now?

It was systemd-boot, now I wiped it

grizzled island Feb 18, 2023, 1:30 PM

#

Before you mount the EFI partition, can you check if there is anything inside of /mnt/boot? (or /boot from chroot)

paper salmon Feb 18, 2023, 1:32 PM

#

Ah, /boot/efi (empty), /boot/grub (fonts grub.cfg grubenv locale themes x86_64-efi)

grizzled island Feb 18, 2023, 1:33 PM

#

Before you mount it delete everything in there first

paper salmon Feb 18, 2023, 1:33 PM

#

Done

#

Deleted everything inside /mnt/boot and mounted partition 1 to /mnt/boot

grizzled island Feb 18, 2023, 1:36 PM

#

You should be able to chroot now

paper salmon Feb 18, 2023, 1:37 PM

#

Is this the right way to install GRUB?

sudo mount --bind /dev /mnt/dev &&
sudo mount --bind /dev/pts /mnt/dev/pts &&
sudo mount --bind /proc /mnt/proc &&
sudo mount --bind /sys /mnt/sys

sudo arch-chroot /mnt

grub-install --target=x86_64-efi /dev/nvme0n1
grub-install --recheck /dev/nvme0n1

paper salmon Feb 18, 2023, 1:37 PM

#

grizzled island You should be able to chroot now

arch-chroot or chroot?

grizzled island Feb 18, 2023, 1:38 PM

#

You don't need to bind the stuff, arch-chroot does that automatically

paper salmon Feb 18, 2023, 1:38 PM

#

Ah, great

grizzled island Feb 18, 2023, 1:38 PM

#

Also, that's not how you install GRUB on UEFI

paper salmon Feb 18, 2023, 1:38 PM

#

Oh.

#

;-; What guide should I follow?

grizzled island Feb 18, 2023, 1:40 PM

#

grub-install --efi-directory=/boot --recheck should be fine for installing

#

then grub-mkconfig -o /boot/grub/grub.cfg

paper salmon Feb 18, 2023, 1:41 PM

#

# grub-install --efi-directory=/boot --recheck
Installing for x86_64-efi platform.
Installation finished. No error reported.

# grub-mkconfig -o /boot/grub/grub.cfg 
Generating grub configuration file ...

Seems good to me

paper salmon Feb 18, 2023, 1:43 PM

#

grizzled island then `grub-mkconfig -o /boot/grub/grub.cfg`

Do I need to do something else?

grizzled island Feb 18, 2023, 1:43 PM

#

Oh wait, the kernel

#

Run pacman -S linux then run the mkconfig command again

paper salmon Feb 18, 2023, 1:50 PM

#

grizzled island Run `pacman -S linux` then run the mkconfig command again

Done and done! :3

grizzled island Feb 18, 2023, 1:50 PM

#

Now you should be able to exit out of chroot and reboot

paper salmon Feb 18, 2023, 1:51 PM

#

It flashed the screen quite a few of times before finally booting 😄

#

Booted up

#

I now need to remove that grub popup asking me to select where to boot

Thank you very much, Me Derp!!!
