 Posted: Sun Oct 06, 2024 5:26 pm Post subject: A problem with efibootmgr |
 |
|
For a long time, I use efistub kernels. The last one was gentoo-sources-5.6.14. Finally, I've compiled 6.11.1 and copied bzImage (as I always did) to /boot/EFI/Gentoo.
My /boot is mounted on /dev/sda2.
| Code: | bilbo ~ # ls /boot/EFI/Gentoo/
bzImage-5.16.14.efi bzImage-6.11.1.efi
|
Then I did, as instructed,
| Code: | bilbo ~ # efibootmgr -c -L "Gentoo-6.11.1" -l '\EFI\Gentoo\bzImage-6.11.1.efi'
BootCurrent: 0001
Timeout: 0 seconds
BootOrder: 0002,0001,0000
Boot0000* Windows Boot Manager HD(2,GPT,d1c57d7e-f924-4f83-a1d7-3868b3e2cff4,0xe1800,0x32000)/\EFI\MICROSOFT\BOOT\BOOTMGFW.EFI57494e444f5753000100000088000000780000004200430044004f0042004a004500430054003d007b00390064006500610038003600

But why Boot0002 looks different? Why HD(1,GPT,89656b86-936e-4711-9832-038a280be148,0x800,0xe1000) instead of HD(2,GPT,d1c57d7e-f924-4f83-a1d7-3868b3e2cff4,0xe1800,0x32000)? The files bzImage-6.11.1.efi and bzImage-5.16.14.efi are in the same directory.
OK, rebooting, pressing F2, then F8 to get to the boot menu. In the boot menu I see only 2 items:
- Windows boot manager
- Gentoo-5.16.14
There is no Gentoo-6.11.1. And
| Code: | bilbo ~ # efibootmgr

Boot0002* Gentoo-6.11.1 VenHw(99e275e7-75a0-4b37-a2e6-c5385e6c00cb)
|
I.e., Boot0002 is some abracadabra instead of the efistub kernel /boot/EFI/Gentoo/bzImage-6.11.1.efi which I put there by the command efibootmgr before the reboot.
Any ideas how to fix this?

| I have the problem that when two efi entries are in the same directory, my uefi firmware deletes one of it. So i have to use another directory for each entry, maybe it's the same for you. |
