I don't know about /boot/efi/EFI/BOOT IMO it shouldn't be there # ls /boot/efi/EFI/ debian The directory "debian" is the entry, you see when the PC boots. What is in /boot/efi/EFI is a bit of UEFI code that tells the system to read from /boot/grub/grub.cfg. You handle this with 1. boot in UEFI mode 2. grub-install /dev/sdX 3. update-grub check with efibootmgr # efibootmgr -v BootCurrent: 0003 Timeout: 1 seconds BootOrder: 0003,0006,0005,0007,0008 Boot0003* debian HD(1,GPT,b5d4d6b6-4111-4591-bf50-71df738ef848,0x800,0x80000)/File(\EFI\debian\shimx64.efi) Boot0005* WDC WDS500G1B0A-00H9H0 BBS(HD,,0x0)AMBO Boot0006* TSSTcorp CDDVDW SN-208AB BBS(CDROM,,0x0)AMBO Boot0007* WDC WDS500G1R0A-68A4W0 BBS(HD,,0x0)AMBO Boot0008* IBA GE Slot 00C8 v1372 BBS(Network,,0x0)AMBO Last but not least it also depends on how the BIOS is done, but recent work quite well, although if you have something like "Fast Boot" etc. could cause problems.
