GRUB refuses to reboot into a new kernal
I found the menuentry/subentry that I wanted to use, as you can see here: https://gyazo.com/b73fa2308145caaed7959a95d71a4bc8
I then changed this in /etc/default/grub to this: GRUB_DEFAULT=1>0
I updated grub with: sudo update-grub
And then rebooted the system with: sudo reboot
It still loads into the same old kernal.
I am using Ubuntu 16.04.

According to the documentation the format is one of
GRUB_DEFAULT="Previous Linux versions>Ubuntu, with Linux 3.2.0-18-generic-pae"GRUB_DEFAULT="Previous Linux versions>0"GRUB_DEFAULT="2>0"GRUB_DEFAULT="2>Ubuntu, with Linux 3.2.0-18-generic-pae"
Your screenshot instead shows
1>0 Ubuntu, with....
It lacks the GRUB_DEFAULT= part, the quotes "…", and is a
mixture of both numeric and textual item selection. Try
GRUB_DEFAULT="1>0"

I changed by GRUB_DEFAULT like you said, updated grub, and restarted the dedi server. It turned back on but was still the old kernal.

@GeorgeAshby Does it work when you manually select the new kernel?

Sadly, I cannot open the boot menu on system startup as I dont have the ability. I bought a dedicated server off of OVH.

Try using the textual version "Previous Linux Versions>Ubuntu" etc. It's much more straightforward IMHO.

Have you seen How to list GRUB's “menuentries” in command-line? It may help to figure out the correct item.
