Ubuntu Black Screen Recovery

Updating Ubuntu only to discover that the kernel update has brought you to a black screen - never fun.

Immediately after the BIOS screen comes up, you will just for a second, see where it says in the upper left to ‘press Esc’ for more options. This is your hidden GRUB (boot) menu, press Esc and then select the third line down. This will allow you to boot into the kernel you were using previously.
