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

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. |

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. |
