And this time run:
sudo nano /etc/default/grub
arrow key down to the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" and add the nomodeset parameter.

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
Tap
ctrl+x to exit, then the y key to say Yes to save, then the enter key to save the current configuration.
Next you must run
sudo update-grub
for the changes to take effect.
Reboot and test.
