I recently created a partition on my Macbook Pro (late 2013 release) to run Ubuntu, following this tutorial.

I managed to have it running smoothly, but I need to update the Kernel to 4.4. I've been following this website's instructions but once I reboot my computer and log back in and run uname -r, the Kernel is still 4.2.0-30-generic. I've also tried pressing Esc to see GRUB, but the apparently installed Kernel 4.4 doesn't appear on the list.

Any ideas?

UPADTE 1:

After Hyltixa helped me, it seems that GRUB is the problem here. After running sudo update-grub this shows up:

Generating grub configuration file ...
Warning: Setting GRUB_TIMEOUT to a non-zero value when GRUB_HIDDEN_TIMEOUT is set is no longer supported.
Found linux image: /boot/vmlinuz-4.4.0-040400-generic
Found initrd image: /boot/initrd.img-4.4.0-040400-generic
Found linux image: /boot/vmlinuz-4.2.0-30-generic
Found initrd image: /boot/initrd.img-4.2.0-30-generic
Found linux image: /boot/vmlinuz-4.2.0-27-generic
Found initrd image: /boot/initrd.img-4.2.0-27-generic
Found Mac OS X on /dev/sda5
done

which shows that the files did in fact get installed. But GRUB is not showing them as options when booting

UPDATE 2

Here's a snapshot of the grub-customizer tool:

Dunno if it should work any different for Ubuntu users than Elementary OS, but to upgrade from 4.2 (or whatever kernel) to the released "LTS" version of 4.4, you can use:

sudo apt-get install linux-generic-lts-xenial

Use : apt-cache search linux|grep xenial to check what is available. If nothing is found, you have to select the correct sources for your distro :)

I noticed that /boot/grub/grub.cfg did not have the proper kernel list in it... after some more searching, the second answer here worked for me:

sudo exec grub-mkconfig -o /boot/grub/grub.cfg

I did that on my elementaryOS and it worked fine! Just make sure you get the right files when you download them, AND you install them in this order.

linux-headers-4.4.0-xxx_all.deb linux-headers-4.4.0-xxx-generic_xxx_i386/amd64.deb linux-image-4.4.0-xxx-generic_xxx_i386/amd64.deb
