hi, im trying to use instlux to do an install of ubuntu, and everytime i try it, it downloads all the files and gets to 59% of the installation and the screen goes blank except for 2 little gray squares in the middle of the screen.

i then try to reboot and it says operating system not found.

ive manage to get windows up and running again by booting off of a windows cd and deleting the new partitions...

any ideas why this is doing it?
