There is nothing to upgrade... This happened to me on a blank machine when trying to install Ubuntu 10.04 GA from a CD. The work around I found was hit escape on the splash screen (where there is a square = little man pic at the bottom). then it goes to the menu and works fine. After installation I have not experienced this on the machine itself.. but happens with the CD everytime.

Problem is with the grub instance on the CD.
