I just thought, maybe I go back to GRUB, but update system with a script, first command normal update, second command install GRUB anyway so just in case grub is updated I’m sure it will be installed and everything will run smoothly. (no problem installing it again even it is installed and no update I think- just to be “like normal”)
Feel free to check Grub 2:2.06.r322.gd9b4638c5-1 won't boot and goes straight to the BIOS after update - #1351 by limotux
Thank you.
