Hello list, |
| 2 |
|
| 3 |
I'm trying to fix my system boot arrangements. I did have a fully working |
| 4 |
system, but something happened a few weeks ago and now I'm struggling. This is |
| 5 |
what I have at the moment: |
| 6 |
|
| 7 |
# grep nvm /etc/fstab |
| 8 |
/dev/nvme0n1p4 / ext4 defaults,relatime 1 1 |
| 9 |
/dev/nvme0n1p2 /boot vfat discard,noauto,noatime 1 2 |
| 10 |
/dev/nvme0n1p5 /var ext4 defaults,relatime 1 2 |
| 11 |
/dev/nvme0n1p6 /home ext4 defaults,relatime 1 2 |
| 12 |
/dev/nvme0n1p7 /home/prh/common ext4 defaults,relatime 1 3 |
| 13 |
/dev/nvme0n1p8 /usr/local ext4 defaults,relatime 1 2 |
| 14 |
[...] |
| 15 |

| 44 |

| 45 |

| 46 |

| 49 |
Boot0001* CD/DVD Drive |
| 50 |
Boot0002* Hard Drive |
| 51 |
Boot0003* UEFI OS |
| 52 |
|
| 53 |
Now, I can make the system bootable by issuing the following commands: |
| 54 |
|
| 55 |
# efibootmgr -b 0 -B |
| 56 |
# efibootmgr --disk /dev/nvme0n1 --part 2 --create --label "Gentoo Linux" -- |
| 57 |
loader '\EFI\Gentoo\vmlinuz-4.19.72.efi' --unicode 'root=/dev/nvme0n1p4 |
| 58 |
initrd=/intel-uc.img net.ifnames=0' |
| 59 |
|
| 60 |
At the next reboot, the UEFI BIOS starts the system directly; it doesn't show |
| 61 |
a menu of boot images. But I want that list so that I can choose which image |
| 62 |
to boot. |
| 63 |
|
| 64 |
Now if I repeat those last two commands but with "--unicode '...'" omitted, |
| 65 |
expecting those values to be picked up from /boot/loader/entries/30- |
| 66 |
gentoo-4.19.72.conf, the BIOS starts some unconfigured kernel - which panics |
| 67 |
because it can't find its filesystem. Again, it doesn't show me a menu, just |
| 68 |
goes for it. |
| 69 |
|
| 70 |
I may have the directory layout wrong under /boot, and that may be my problem. |
| 71 |
I think I used a layout from systemd-boot, which I no longer use. |
| 72 |
|
| 73 |
Can anyone see what I'm doing wrong? Do I have to go back to bootctl from |
| 74 |
systemd-boot? |
| 75 |
