Ubuntu – How to boot with an older kernel version

grub2kernel

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
