Bootloader won't load anymore on start-up

Yes, there are several ways to fix a non-functional bootloader after a Linux update. Here are some methods you might find helpful:

1. Use a Linux live CD/USB: You can boot from a Linux live CD or USB, then use a tool like chroot to access and modify your system files.
2. Reinstall the bootloader: If you’re using GRUB, you can try reinstalling it. Here’s a command that might help: grub-install --target=x86_64-efi --efi-directory=/efi --bootloader-id=GRUB.
3. Use Boot Repair: Boot Repair is a simple tool to repair frequent boot issues. You can use it to restore the GRUB bootloader.
4. Change the boot order in UEFI firmware settings: If you can boot into another OS like Windows, you can enter the UEFI firmware settings from the boot options, change the boot order to make Linux boot first, save changes and exit.
5. Switch to another bootloader: If you’re having persistent issues with your current bootloader, you might consider switching to another one, such as GRUB2.

Remember to backup your data before making any changes to your system.

Good luck! 😊
