I don't think so, but the terminology is certainly confusing. Peter |
5 |
asked where efibootmgr writes something. What is on /dev/sda2 could be |
6 |
grub.cfg if it were mounted at /boot, and the grub booting stub (I |
7 |
forget the correct name, but grubx64.efi) might be on /dev/sda2 if it |
8 |
were mounted at /boot/EFI. However, efibootmgr doesn't mess with either |
9 |
of those. It deals with what is stored in the UEFI boot firmware. That |
10 |
entry, which is read by the UEFI at boot time, runs the entry in the EFI |
11 |
disk partition (usually under /boot/EFI), which then runs the kernel |
12 |
(and possibly initramfs) in /boot. Unfortunately, "boot record" is |
13 |
probably too general a term. |
