I am not an advanced user. Ubuntu is the only operating system I use. 4 days ago Ubuntu said I needed to update my UEFI to the 2023 version, so i did. After i restarted, it said it still needed to update, so i clicked on it again. But this time the update took a lot longer and seemed stuck so i just canceled it for now.
I shut down my laptop and went to turn it on the next day, but it seemed like it froze after i tried to boot ubuntu. (I tried multiple times). So i entered the advanced options menu and clicked on recovery mode, but it got stuck on loading initial ramdisk. I used a live usb and clicked "try or install ubuntu" but it gave me a blank screen for several hours. Then i decided to go back to the gnu grub menu and check the memory, but it said "bad shim signature". then i realized i could just temporarily disable secure boot and use ubuntu to reinstall grub. So i went back to firmware settings (mine is insyde H2O BIOS) and disabled "enforce secure boot" since the regular secure boot setting was locked, but it seems like this did disable secure boot. It still didnt work. I did the memory test again but this time i got a blank screen. Using ls in the grub command line, i can only see .efi files. In the firmware settings there is nothing related to CPU.
All of the solutions i saw online either didnt match up to what grub showed me or they were too complex for me. If anyone could give me some advice about this i would really appreciate it.
