If you followed the handbook /dev/sda2 would be where the boot record lives.
I don't think so, but the terminology is certainly confusing. Peter
asked where efibootmgr writes something. What is on /dev/sda2 could be
grub.cfg if it were mounted at /boot, and the grub booting stub (I
forget the correct name, but grubx64.efi) might be on /dev/sda2 if it
were mounted at /boot/EFI. However, efibootmgr doesn't mess with either
of those. It deals with what is stored in the UEFI boot firmware. That
entry, which is read by the UEFI at boot time, runs the entry in the EFI
disk partition (usually under /boot/EFI), which then runs the kernel
(and possibly initramfs) in /boot. Unfortunately, "boot record" is
probably too general a term.

Subject: [gentoo-user] UEFI booting again
I'm still wrestling with my system and its not booting.
Can anyone please tell me precisely where 'efibootmgr -c ...' writes a boot
record, or whatever it's called? My machine seems unable to store what I give
it, and I suspect that the BIOS ROM has failed. Big expense if so.
