Ubuntu – How to set previous kernel as default in GRUB (Grub customizer)


Can you guys please help me use Grub Customizer to set an older version of the kernel 4.4.0 of Ubuntu 16.04 LTS as default when booting? I'm not using a dual boot system, and I have installed 4.4.8 kernel to help me solve the suspend problem, but it's draining my battery.

What do I have to do, I wouldn't want to f*** things up.

Ok .. Decided to give it Grub Customizer a try on a VM box so I didn't screw anything up. I was able to change the default kernel without any issues. Here is how I did it.

enter image description here

In the General settings tab I clicked the pulldown for predefined. It listed all the kernels available. I chose the 3.19.0-58-generic and clicked save ... I rebooted into that kernel. Even though I was worried about it putting the name instead of the numeric value .. it seems to work fine.

So you would have no problems doing the same thing .. just choose the generic one for the kernel you want to use .. not the (upstart) or (recovery mode)

In your case .. the pulldown would probably say either Ubuntu, with Linux 4.4.0-21-generic or Advanced options for Ubuntu>Ubuntu, with Linux 4.4.0-21-generic
