# GRUB

TIP

In grub2 you'll need to install additional package called os-prober. It will improve the detecting system. E.g. to recognize Microsoft while dual-booting. Also consider to install ntfs-3g, so while dual-booting it will allow you to mount ntfs partitions.

pacman -S grub os-prober ntfs-3g
mkdir /boot/EFI/GRUB
grub-install --target=x86_64-efi --efi-directory=`your boot partition` --bootloader-id=GRUB

Issues or special use cases you can find at grub2 on archwiki

We need to generate config file /boot/grub/grub.cfg, which you should generate and regenerate when your main config /etc/default/grub was edited.

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

# Configuration

To enable resume after hibernation you can do:

GRUB_CMDLINE_LINUX_DEFAULT="resume=UUID=PutSwapUuidHere quiet"

TIP

lsblk -f shows you UUID.

By default grub-mkconfig determines the UUID of the root filesystem for the configuration. To disable this, uncomment:

...
GRUB_DISABLE_LINUX_UUID=true
...
