19 You don't have a BIOS with a UEFI system.

23 The boot manager in the firmware picks an EFI boot image from the ESP,
24 usually sda1. Once it loads that it's job is done. The boot image can be
25 a kernel or a secondary bootloader like GRUB.

27 Really, there is rarely a point in using GRUB on a UEFI system. Any
28 bootloader adds extra complication, GRUB does it in spades. Just use a
29 boot manager like rEFInd or systemd-boot - the latter is the simpler to
30 work with AFAICT.
