1. Create a mountpoint
# mkdir /mount/point
sudo mkdir /media/disk
sudo mount /dev/sda5 /media/disk
 
2. Mount /proc /sys /dev to chroot
# mount -o bind /proc /mount/point/proc
# mount -o bind /dev /mount/point/dev
# mount -o bind /dev/pts /mount/point/dev/pts
# mount -o bind /sys /mount/point/sys
 
mount --bind /dev /media/disk/dev
mount --bind /proc /media/disk/proc
mount --bind /sys /media/disk/sys
mount --bind /dev/pts /media/disk/dev/pts
 
3. Copy resolv.conf to networking
# cp /etc/resolv.conf /mount/point/etc/resolv.conf
 
4.Open bash in chroot
# chroot /mount/point /bin/bash
 
sudo mkdir /media/disk && sudo mount /dev/sda5 /media/disk && sudo mount --bind /dev /media/disk/dev && sudo mount --bind /proc /media/disk/proc && sudo mount --bind /sys /media/disk/sys && sudo mount --bind /dev/pts /media/disk/dev/pts && sudo cp /etc/resolv.conf /media/disk/etc/resolv.conf && sudo chroot /media/disk
