I'm trying to install arch following the wiki steps:

- I have mounted the file system

mount /dev/sda2 /mnt

- I have installed the base package group

pacstrap /mnt base

- Then chroot

 arch-chroot /mnt 

- Installed  the packages grub and efibootmgr:

pacman -S grub efibootmgr

- Mounted the EFI partition:

mount /dev/sda1 /efi 

- Executed grub-install:

grub-install --target=x86_64-efi --efi-directory=/efi --bootloader-id=GRUB

- Generate the main configuration file:

grub-mkconfig -o /boot/grub/grub.cfg

Then I reboot the system but anything bootable is detected. I supose I mising an importante step.

I'm not sure which commands output would be useful to show here, so just tell me and as fast as posible I will edit the main post with it.

efibootmgr -v

Re: [SOLVED] GRUB does not start after installation

I have no idea. Just want to say that you are missing the final g in grub.cfg.

grub-mkconfig -o /boot/grub/grub.cf

If the commands you listed are the only ones you run, it will have to do with your EFI-partition (/dev/sda1) not being mounted. With the grub-install command,  your are installing grub in your root directory of the /dev/sda2 partition. Therefore, when your system boots and looks for bootloaders in the /dev/sda1 partition, it will not find your GRUB installation.

Now, try mounting your EFI-partition before installing GRUB:

mnt /dev/sda1 /boot

After that, install GRUB in the mounted folder:

grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=GRUB

Don't forget to create a new config in this folder before rebooting:

grub-mkconfig -o /boot/grub/grub.cfg

Good luck!

The OP did mount the ESP, check their post again.

@OP: I presume you have disabled Secure Boot?

If so then try setting the Arch boot entry as first in the boot order:

# efibootmgr -o 0001,2001,2002,2003

In case of failure, note that there have been threads in which too many NVRAM entries caused problems so deleting some of them might help:

# efibootmgr -b xxxx -B

Replace xxxx with the boot number to be deleted.

If that still doesn't work then try copying /EFI/GRUB/grubx64.efi to /EFI/BOOT/bootx64.efi (on the EFI system partition), if your UEFI firmware is particularly defective then you may have to use /EFI/Microsoft/Boot/bootmgfw.efi

See https://www.rodsbooks.com/efi-bootloade … ive-naming for more on this.

Re: [SOLVED] GRUB does not start after installation

My bad. Although it looks like /dev/sda1 is mounted at /efi. However, the EFI directory is usually a in the ESP. This surely must matter, since in OP:s command, the root directory of the partition is specified as the EFI directory?

Re: [SOLVED] GRUB does not start after installation

I have been reading this issue in the efibootmgr git and a lo of people with an Acer Aspire V has the same problem (my laptop is also an Acer Aspire V). I was planning to do dual boot so I guess the easiest option is to install windows and then inside windows change the boot path with this order:

bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi

That is what I have been doing since the last time, but I felt it was not the best way.

That should be fine, AFAIK.

That command tells Windows' UEFI loader (bootmgfw.efi) to start \EFI\ubuntu\grubx64.efi so copying /EFI/GRUB/grubx64.efi to /EFI/Microsoft/Boot/bootmgfw.efi will probably work and save you from having to install Windows.

Try /EFI/BOOT/bootx64.efi first though, that at least is actually defined in the UEFI standard.

Re: [SOLVED] GRUB does not start after installation

I think this worked. It's not the GRUB menu I'm used to, it's a command line, but at least something booted a part from my USB.
My file tree now looks like this:

EFI:
+---BOOT:
|   +----bootx64.efi
+---EFI:
|   +---GRUB:
|       +---grubx64.efi
+---arch:
|   +---grubx64.efi
+---arch_grub:
    +---grubx64.efi

I'm not sure if this is how it should look. I copied the /EFI/EFI/GRUB/grubx64.efi to /EFI/BOOT/bootx64.efi

It needs to be /EFI/BOOT/bootx64.efi on the EFI system partition so if the ESP is mounted to /EFI then you should copy it to /EFI/EFI/BOOT/bootx64.efi

Did simply changing the boot order not work?

Re: [SOLVED] GRUB does not start after installation

The ESP is mounted in /boot and changing the boot order does not work because once I reboot it return to the original order.

So have you placed the GRUB .efi loader at /boot/EFI/BOOT/bootx64.efi? If that doesn't work try /boot/EFI/Microsoft/Boot/bootmgfw.efi

If you're going to run your system with the ESP mounted to /boot then the kernel image & initramfs also need to be there, mounting the ESP then re-installing the kernel package should do that for you, remember to re-install the grub package as well so the modules are in the right place.

EDIT: grub.cfg will also have to be relocated to the ESP, that's probably why you booted to a (grub?) command line.

Re: [SOLVED] GRUB does not start after installation

Both of this options

 /boot/EFI/BOOT/bootx64.efi

and

/boot/EFI/Microsoft/Boot/bootmgfw.efi

work but I have the problem that both of them launch a command line instad of the typical menu. Where is supposed to be relocated the grub.cfg?

Re: [SOLVED] GRUB does not start after installation

When you say "command line" do you mean a GRUB prompt?

edoelas wrote:

/boot/grub/grub.cfg

I think the problem here is that you originally installed with /boot on /dev/sda2 but now you have mounted /dev/sda1 to /boot instead so you need to re-populate the /boot folder over on /dev/sda1 (and change /etc/fstab as well).

You will also have to run the `grub-install` command again so the bootloader is searching the correct partition for the modules and configuration file.

It may be best to start again from scratch and mount /dev/sda1 to /boot (/mnt/boot from the live environment) before running `arch-chroot` so that everything is in the right place.

Okay, so I format the partitions, mount /dev/sda2 on /mnt, run pacstrap and genfstab, mount /dev/sda1 on /mnt/boot, make chroot, install grub and efibootmgr, run grub-install, run grub-mkconfig, copy the  grubx64.efi /boot/EFI/BOOT/bootx64.efi, reboot and everything should work. I'm right?

No, mount both of the partitions before running the `pacstrap` & `genfstab` commands.

You can use the --removable flag for the `grub-install` command to copy the .efi loader to ${ESP}/EFI/BOOT/bootx64.efi automatically.

Re: [SOLVED] GRUB does not start after installation

If I try to mount /dev/sda1 on /mnt/boot after mounting /dev/sda2 on /mnt but before running pacstrap I get the error:

mount: /mnt/boot: mount point does not exist.

mount /dev/sda2 /mnt
mkdir /mnt/boot
mount /dev/sda1 /mnt/boot

Then pacstrap, etc.

Edit: When running grub-install (inside the chroot), --efi-directory= should be /boot if following the above.
