I followed the instructions shared here: I installed Zorin 16 Pro as my only OS and I only get a grub error when I boot up - #2 by Aravisian
I found my filesystem on (hd0,gpt5) but when I am doing the following to boot on the previous kernel
grub> set root=(hd0,gpt5)
grub> linux /boot/vmlinuz-6.5.0-15-generic root=/dev/sda5
grub> initrd /boot/initrd.img-6.5.0-15-generic
grub> boot
I get an error saying that /dev/sda5 doesn't exists
