gjv777; Hey ;
I just completed a install of lubuntu 13.04 that was a challenge... what I wound up doing, after a failed install attempt, was zeroing out that hard drive (going to extreme in my case), choosing the "nomodeset" option and not accepting to install updates or 3rd party software. Third try for me was the charm; installed without a hitch. [+ google-chrome and my wife is a happy camper !]
edit: Oh! once the installer crashed when I tried to use a capital letter in the "username" !
frustrating to keep trying, lesson: do not give up
