 Posted: Wed May 26, 2021 10:39 am Post subject: efibootmgr cannot boot (solved, efi was 32bit) |
 |
|
Hello, I have a kernel compiled but I can't boot it. I am constantly working by mounting the drive where gentoo will grow up and chrooting there from usb stick. I installed stage3 and have emerge and various other utils working. I try to do it without a bootloader, with efibootmgr, and without initramfs. Whenever I reboot I have this light blue screen with the blinking question mark folder on the Macbook2.1. On the internal disk, there already pre exists esp created years ago by debian. The debian root partition was resized to make place for a gentoo partition. The resizing messed it and it seems unbootable, but we don't mind. The debian entry in the esp is booted ok by efibootmgr. What we cannot boot is the efi/boot entry labeled "gentoo". Next thing I plan to do is study the minimal installation gentoo usb boot mechanism as it boots successfully but I am bored going through this all alone. Here is the info gathered, concatenated from terminal in a txt file and uploaded from another machine, I hope the style is ok for humans:...

OP already provided /etc/fstab, and stated in the opening post that this system is not using grub. |

Then this how you do
If you prefer to not use grub then plz copy the kernel to
/boot/EFI/boot
and create an efistub efibootmgr entry
| Code: |
efibootmgr --disk /dev/sdX --part Y --create --label "Gentoo" --loader /vmlinuz.......... --unicode 'root=PARTUUID=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX rw --verbose
|
Although it would be a million times better to use grub and an initrd the good old tested orthodox way.
You do have grub after all installed in your machine no???
It shows in /boot
For debian no?
And
furthermore consider plz mounting the ESP on /boot/efi
NOT
on /boot
You do not need an efivar entry in fstab unless you want them mounted ro
This is what i do
| Code: |
efivarfs /sys/firmware/efi/efivars efivarfs ro,nosuid,nodev,noexec,relatime 0 0
|
and remount them rw on a need-to basis
Sorry Hu for my lapse of attention....

Hey jaglover why are you doing this to me, I dreamed of booting without a loader and shouting it to the neighbourhood  And that's the only uefi machine I have. So I abandon efibootmgr and will try with syslinux. In that case I guess I need the efi mixed mode enabled ...
By the way, your installation notes are interesting and inspiring. |
