I amving 5 Ubuntu live cds, i had tried using live cd earlier and i was able to use it. But now whenever i try to use live cd it give me error that smething cannot be installed 9cant read from cd) i tried using all 5 cds but same error comes after scnning my hardware. Earlier i was uing single HDD (20Gb) and now using 2 ( 20+80) is there problem because of this. I am using older version of ubuntu ( seperate live and install cds.) please help me to run live cd.
