Help with grub-install, cannot open device.map and failed to get

Hello.

I try install ArchLinux with official guide, but I get error during grub-install.

I have this layout:
/dev/sda1 EFI System
/dev/sda2 Linux root
/dev/sda3 Linux home
/dev/sda4 Linux swap

During installation, I wrote this commands:
mkfs.ext4 all /dev/sda without sda4
mkswap and swapon to sda4
mount /dev/sda2 /mnt
mkdir /mnt/boot
mount /dev/sda1 /mnt/boot

Should I have written mkdir /mnt/boot/efi and mount/dev/sda1 /mnt/boot/efi instead of those commands?

I install grub with pacman -S grub.

I get this:
cannot open /boot/grub/device.map
failed to get canonical path of /boot/efi

Thanks for help!

Welcome to the forums Sm1Th

Why did you format sda1 as ext4 instead of FAT?

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

Oh, I am idiot, I forgot on this.

Should I format all sda to fat instead of ext4?
What do you prefer?
I am prefering ext4, but I will share a few files with Windows, but I read somewhere, that ext4 has a better handling with partitions.

Do you think, that the wrong format is the problem or /boot/efi instead of only /boot too?

Sorry for my English, I am still learning it.

What do you want to use as the ESP /boot or /boot/efi ?

Only the EFI boot partition (sda1) should be formatted as FAT, ext4 is fine for the rest.

Mounting sda1 as /boot is correct (you can use /boot/efi but it makes things more complicated).
