grub2 - How can I boot with an older kernel version?


The latest kernel is causing problems with my sound, which worked fine with an older version. As I have only Ubuntu installed, Grub is not getting displayed while booting. How can I manually choose my kernel version while booting?



The simplest way to display your Grub is to press and hold the SHIFT button while booting.


As an alternative, you can always display Grub without it booting any particular kernel:


gksudo gedit /etc/default/grub

change GRUB_TIMEOUT to -1 and comment out GRUB_HIDDEN_TIMEOUT


finish off by running


sudo update-grub
