I have laptop with 512MB ram and 80 GB HDD, dual core 2.0GB Hz speed, 32bit earlier i was using W-XP on this once i have tried to install Win7 and it get all problematic. now have tried to install back Win-Xp but it get hanged in between and shows the message , file not found. hence decided to go for Ubuntu.
I Have already downloaded Ubuntu 14.04 ISO file. I want to know how to install it from USB and if the message of "file not found" reappears, then what to do.
