 ```sh
-for dir in dev proc sys run; do mkdir -p /mnt/$dir; mount --rbind /$dir /mnt/$dir; mount --make-rslave /mnt/$dir; done
-mkdir -p /mnt/boot
-mount /dev/<disk name, boot partition number> /mnt/boot
+mount <root partition> /mnt
 ```
-Replace **<disk name, boot partition number>**, with the actual disk name, and boot partition number (ie. `/dev/sda1`).
+Replace **<root partition>** with the root partition (ie. `/dev/sda3`).
 
-You are going to need to set up the network if you haven't already.
+If you are using UEFI, mount the boot partition.
+```sh
+mkdir -p /mnt/boot/efi/
+mount <boot partiton> /mnt/boot/efi/
+```
+Replace **<boot partition>** with the boot partition (ie. `/dev/sda1`).

+```sh
+mount -t proc none /mnt/proc
+mount -t sysfs none /mnt/sys
+mount --rbind /dev /mnt/dev
+mount --rbind /run /mnt/run
+```
