Just installed Linux Mint 21.2, except no one told me about UEFI secure boot. Trouble I had with that on Linux but I've found a solution of sorts, I don't know if the steps I took were necessary but it works for me.
sudo grub-install /dev/sda1
sudo grub-install /dev/sda1 --no-uefi-secure-boot
reboot
remember to keep the secure boot on for this to work.
