We need more information to help you. Which version is currently installed? How did you install it? Did the install finish? Do you have any other OSs installed? What happens when you boot?

What happens after 'restart'? Does it boot properly?
Which *BUNTU controls the GRUB?
Which *BUNTU is causing this issue? Can you boot other 'BUNTUS without any issues?

What Graphics do you have on board? Have you created SWAP partiton?
