Whatever boot issue you're facing or system breakage you encounter, that would be neat to be able to fix you system rather than reinstalling it, isn't it?
I'll give you a few hints to do that, especially if you have a setup similar to mine.
I hope you have an AL USB key ready to go.
Unless you have an English qwerty keyboard, don't forget to change your keyboard layout for a good start.

You can use lsblk -f to identify your ESP and your root partition.
In case of an encrypted partition, unlock it (eg. LVM on LUKS).
1 | cryptsetup open /dev/sdc2 cryptlvm |
Mount the root partition then the ESP (and swap if you have one).
1 | mount /dev/myvg2/root /mnt |
Let's change root into the system to be saved:
1 | arch-chroot /mnt |
That may not be a bad idea to drop privileges to normal user to prevent accidents. With great power comes great responsibility.

If planning to fix boot images and having a bind mount, one doesn't want to forget to mount it before generating initramfs images or something.
1 | sudo mount --bind /efi/EFI/arch /boot |
Finally, please try anything in your power to save that poor system.
