 |
|
Hello!
I'm trying to dualboot Arch Linux and Gentoo but I'm not able to get my Gentoo partition to boot with systemd-boot.
I first installed Arch, mounted the boot partition (vfat) and did "bootctl install" and filled /boot/loader/entries/arch.conf. Everything works fine there.
I then installed Gentoo on a separate partition, mounted the same boot partition, compiled the kernel with genkernel, filled /boot/loader/entries/gentoo.conf and tried booting but was unable to. I get a message saying:
| Code: |
Error loading /kernel-genkernel-x86_64-4.14.83-gentoo: Unsupported
Failed to execute Gentoo (/kernel-genkernel-x86_64-4.14.83-gentoo): Unsupported
|
Is my boot loader entry for Gentoo correct? Do I have to do anything else to reuse Arch's systemd bootloader?
| Code: |
title Gentoo
linux /kernel-genkernel-x86_64-4.14.83-gentoo
initrd /initramfs-genkernel-x86_64-4.14.83-gentoo
options cryptdevice=/dev/nvme0n1p4:cryptroot root=/dev/mapper/cryptroot rw

Update: I just removed Arch's bootloader with bootctl remove and then chrooted into the Gentoo partition and installed it from there with bootctl install. I still get the same problem, so my issue should have nothing to do with Arch. Are more things required to use systemd boot in Gentoo? |

and what if your genkernel kernel have a configuration problem that does not make boot possible because of it? Are you sure it boot properly with an other bootloader?
