i have a PC (not very good its time to confess i have an E-machine...but i got it free) as i was installing ubuntu it would go though most of the process,get to intsalling the softwear, it would stall and then after about an hour would say it cannot complete this. it wiped all the windows and everything else off teh pC and i had to get a guy i know to come and re-install windows because i was stuck with nothing.
i was sure i did something wrong and tried it again with teh same results, i checked the CD integrity before i attempted to install and that should eb fine. this guy told me i would not get linux working on this so..............
