Hi George ,

switch to a real console (tty1) by pressing CTRL+ALT+F1 , try set the resolution for GRUB to 640x480

Open the file /etc/default/grub with nano or vim Locate the line: # GRUB_GFXMODE = 640x480
uncomment ( remove the '#' ) from the following line

GRUB_GFXMODE = 640x480

This will set the res to 640x480 GRUB - it is a safe resolution, which should not be a problem. If you wish, you can gradually change, until you reach the limit.

save your change in vim or nano and exit , then
Update GRUB: sudo update-grub
Reboot the Machine by pressing Ctrl+Alt+Del

you could also use the live cd to do so .. follow steps in the link
