[SOLVED] Problem with GRUB

bobadigo · 2016-09-17 23:40:50

Good morning.
I was installing Arch on an 250gb SSD. So i created 4 partitions: 512M EFI (vfat) (/dev/sda1), 150G linux filesystem (ext4) (/dev/sda2), 16G swap partition (/dev/sda4) and the, remaining (~70G) linux filesystem (ext4). I mounted the /dev/sda2 to /mnt, the /dev/sda1 to /mnt/boot, the /dev/sda3 to /mnt/home and simply turnet the swap on. After the first downloads, i entered Arch (always from USB). So i installed grub and efibootmgr, but when i tryed "grub-install —efi-directory=/boot", it returned "Installing for i386-pc platform. grub-install: error: install device isn't specified.". So I (scared), rebooted the PC, and (as expected, it didn't boot). So i run the USB again, mounted the partitions (swap included), and tryed "grub-install —target=x86_64-efi —efi-directory=/boot" (target because I'm running on a 64 bit machine), but this time, it returned "Could not prepare Boot variable: No such file or directory. Installation finished. No error reported". So i rebooted to test, and it didn't work again.
What can i do? Thanks

It appears you didn't enter the command correctly. From the wiki:

# grub-install --target=x86_64-efi --efi-directory=esp --bootloader-id=grub

The commands you tried were:

grub-install —efi-directory=/boot

grub-install —target=x86_64-efi —efi-directory=/boot

Your second command was almost correct, but as you can see you're missing the bootloader ID part.

I tryed right now:

# grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=grub
Installing for x86_64-efi platform.
Could not prepare Boot variabile: No such file or directory.
Installation finished. No error reported.

Same as yesterday..

P.S. I had installed windows 10 on a 500GB HDD. I tryed to remove it, but the problem persist

Are you booted in UEFI mode?

Are all of the other requirements for UEFI variable support satisfied?

If your motherboard is not accepting new NVRAM entries then you can try the default .efi loader location instead:

# grub-install --target=x86_64-efi --efi-directory=/boot --removable

Note that "--bootloader-id=" is for convenience only

I checked, and i am not running in EFI mode. I don't know it is possible, considering that i am using a z170 motherboard..
How can i boot using EFI mode?

Likely an option in your BIOS. Each one is named differently though... google 'brand/model boot efi mode'

I disabled "Secure Boot"and "Storage Boot Option" to UEFI. Nothing, always the same.

EDIT

Ok, now I am in EFI mode. To do that, i went to "boot override" and selected "UEFI:USB" (first it was just "USB").
I try installing again, i will tell you how it goes.

EDIT

Installation succesfully done, that to all for the answers!
