My laptop does not boot Freya.So I think that I should upgrade my kernel to 4.4.But the system is unbootable and gives a error and does not show the GUI.
But how could I do this when it doesn't boot
You can boot into a Flash Drive with elementary OS and chroot into your machine.
First get root with sudo su
, and create some directory using mkdir /mnt/mainOS
.
Then just mount your HDD with the mount /dev/<your id> /mnt/mainOS
command and chroot /mnt/mainOS /bin/bash -i
into it. Your bash will now behave like you would be in your normal machine. Upgrade the kernel as usual, !exit
! and reboot
should then do the rest. ;)
Tips: You can detect your drives with df -h
.
