This is the second time today that installation appears to have been successful. Here is the complete message:
"Installation is complete. You need to restart the computer in order to use the new installation."
The button reads" "Restart Now". It does not reference the flash drive used for installation. This time I'll leave the flash drive in.
Hey, another blank screen. Way to go Ubuntu. You still suck.
I think it's safe to remove the flash drive. Power off. Remove flash drive. Bye.
