according to this page:

Ubuntu Forums

You should do:

  1. Open terminal and enter.

sudo gedit /etc/default/grub

  1. Now change

GRUB_CMDLINE_LINUX=""

to

GRUB_CMDLINE_LINUX="nomodeset"

Close gedit to return to the terminal window. Now we need to update grub.cfg

update-grub

That should do the trick

The OP cannot install Ubuntu yet. Also, please use code formatting by either enclosing code in `backticks` or putting four spaces before code on its own line. –  hexafraction Oct 9 '12 at 19:14
