First, boot to recovery mode and drop to a root shell.
1) Mount the file system as R/W: mount -o remount,rw /
2) Next, run sudo nano /etc/default/grub
3) Then add nomodeset to GRUB_CMDLINE_LINUX_DEFAULT:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
Becomes:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
And then save by hitting Ctrl+O, then exit nano with Ctrl+X
4) Finally, run:
sudo update-grub
sudo reboot
