 |
|
I'm installing Gentoo ~amd64 (systemd) on a new computer and have come to where installing the grub bootloader.
I'm using the Gentoo LiveGUI install media.
When I enter grub-install I get this error message:
| Quote: | Installing for x86_64-efi platform.
grub-install: error: cannot find a device for /boot/grub (is /dev mounted?). |
lsblk:

└─nvme0n1p4 259:8 0 976.6G 0 part /home |
The install drive is nvme0n1
I have tried both rbinding the folders before chroot manually and usingthe arch-chroot /mnt/gentoo
I have set the following USE flag for GRUB:
| Quote: | | [ebuild R ] sys-boot/grub-2.12-r5:2/2.12-r5::gentoo USE="device-mapper fonts nls sdl themes truetype -doc -efiemu -libzfs -mount -secureboot (-test) -verify-sig" GRUB_PLATFORMS="efi-64 -coreboot -efi-32 -emu -ieee1275 (-loongson) -multiboot -pc -qemu (-qemu-mips) -uboot -xen -xen-32 -xen-pvh" 0 Ki |
and for installkernel:
| Quote: | [ebuild R ] sys-kernel/installkernel-48-r1::gentoo USE="grub -dracut -efistub -refind -systemd -systemd-boot -ugrd -uki -ukify" 0 KiB
|
I don't understand why grub-install don't work the /boot/grub (empty) folder is there and has root rwx access. |

Grub does not find the place where /boot/grub should be. Normally /boot is part of / or on its own /boot-partition.
According to | Quote: | | Code: | ├─nvme0n1p1 259:5 0 100M 0 part /boot/efi
├─nvme0n1p2 259:6 0 593.4G 0 part
├─nvme0n1p3 259:7 0 293G 0 part /var
└─nvme0n1p4 259:8 0 976.6G 0 part /home |

you have /boot/efi, /var and /home, but I do not see your system partition.
I assume /dev/nvme0n1p2 should be used for your system? |

Jea something seems to have gone wrong when the root partition was mounted nvme0n1p2  .
I exited out of the chroot and rebooted the machine and when I mounted the root partition again it was empty
Well, have to start from the beginning again.
Thankfully I copied the etc folder to my rescue drive first. |

When you try again, make sure that you have in your make.conf a correct setting - I am missing the second " here:
| Code: | | GRUB_PLATFORMS="efi-64 |
should be:
| Code: | | GRUB_PLATFORMS="efi-64" |
Edit: Please forget this post ... maybe I wasn't really awake yet.

That's not necessarily a problem, I don't have anything grub related in make.conf and it still works perfectly fine.
What I have though is:
| Quote: | | [ebuild R ] sys-boot/grub-2.12-r5:2/2.12-r5::gentoo USE="device-mapper fonts mount nls sdl themes truetype -doc -efiemu -libzfs -secureboot (-test) -verify-sig" GRUB_PLATFORMS="efi-64 pc -coreboot -efi-32 -emu -ieee1275 (-loongson) -multiboot -qemu (-qemu-mips) -uboot -xen -xen-32 -xen-pvh" 0 KiB |
