When you arrive at this step below, just press shift key on your keyboard.

Press e to edit your start command, change quiet splash to nomodeset  and press Ctrl+X on keyboard.

After you reboot successfully, open a terminal, and follow the tips below:

You should add this option to /etc/default/grub, firstly:
sudo nano /etc/default/grub

and then add nomodeset to GRUB_CMDLINE_LINUX_DEFAULT:
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

And then simply run:
sudo update-grub
