[!RESOLVED!] GRUB Rescue mode post Arch Linux install attempt

[sharp sphinx]

I followed this guide: https://youtu.be/68z11VAYMS8 and after reboot, it enters GRUB Rescue mode post install with the error in the picture. I would like some help, it would be much appreciated.

I'd try reinstalling grub and reconfiguring it first

You can either chroot from a live iso and reinstall grub, or boot manually from grub recovery and reinstall grub

how do i manually boot from recovery

nvm think i might have found out how to get in

[zenith sable]

Its hard to explain in here

But I can try if you still want me to tell you

[sharp sphinx]

Sure, bet it's easier than going to boot options after interrupting boot and having to navigate to the efi file from there

You to type ls

You will get a list with the partitions on the disk

They will look like (hd0,msdos1) or (hd0,gpt3)

Something like that

By typing ls (hd0,gpt3) for example you will get Its filesystem type (ext4, likely) and Its size

Doing that you are supposed to discover whats your root partition, the one were you have linux installed

Then you type set root=(hd0,gpt3) asuming thats your root partition

Then you type the following things: ```

insmod normal
normal
``` (do not type the >)

The screen will reset and the recovery will reload

Now by typing ls / you shoukd be able to see the contents of your root partition

Now you want to see the kernel and initramfs you are using in that system by looking at the contents of /boot, you can do It by simply typing ls /boot

Once you kniw that, asuming your kernel and initramfs are vmlinuz-6.3 and initramfs-6.3.img as an example you do the following:
linux /boot/vmlinuz-6.3 root=/dev/sda3 ro (Asuming your root partition Its /dev/sda3, notice how /dev/sda3 matches (hd0,gpt3)
initrd /boot/initramfs-6.3.img
And finally:
boot

After doing this, your computer should boot normally, if It doesnt you should fallback to your initramfs, and you will need to chroot to your root partition from there, to reintall grub (ping me in that case)

Once your system Its up, to recover grub, get into a root shell and type the following for BIOS:
grub-install /dev/sda (without numbers)
If you are using uefi, depends on where your boot partition is mounted, you can check the contents of /etc/fstab by typing cat /etc/fstab to know. Asuming your boot partition is mounted under /boot/efi/, as It should:
grub-install --target=x86_64-efi --efi-directory=/boot/efi --removable

And finally, regardless of if you are using UEFI or BIOS, you want to type:
grub-mkconfig -o /boot/grub/grub.cfg
At this point you should be able to reboot normally.
