|
I am having issues booting after installing grub to the ESP (at least I think that is what I am doing  ) For reference, this is the machine I have: https://wiki.gentoo.org/wiki/Dell_XPS_13_9343
Here is the current layout of my disks (from gdisk -l):
| Code: | GPT fdisk (gdisk) version 0.8.10
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: present
Found valid GPT with protective MBR; using GPT.
Disk /dev/sda: 500118192 sectors, 238.5 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): CBA6A552-AD4A-498D-AC86-F518C952E774
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 500118158
Partitions will be aligned on 2048-sector boundaries
Total free space is 8125 sectors (4.0 MiB)
Number Start (sector) End (sector) Size Code Name
2 6144 268287 128.0 MiB EF00 boot
3 268288 25434111 12.0 GiB 0700 swap
4 25434112 500116143 226.3 GiB 0700 rootfs |
The /boot partion is vfat, the / partition is ext4, and the swap partition is swap.
before I emerge'd grub I add the correct efi-64 line to my make.conf:
| Code: | | GRUB_PLATFORMS="efi-64" |
and when I installed GRUB I used the command:
| Code: | | grub2-install --target=x86_64-efi --efi-directory=/boot |
which completes without error and I see the /boot/EFI/gentoo directory was written after this command is run.
Also after this is run, I see an entry for "gentoo" in efibootmgr -v listed as the first boot option:
| Code: | BootCurrent: 0023

However whenever I re-boot my machine, it appears that these EFI settings are lost. The boot option for gentoo is not removed, but the boot order is always changed? Any thoughts on what could be going on? I can post any more additional information as needed. |
