Ok! Got this sussed now. Zeph gave me a clue when he mentioned winrar reading iso's. Like a dick i was copying the file structure onto dvd hence the coasters
Solution got rid of winrar and windows correctly showed it as an iso file
A few tips (should add to the linux knowledge base i s'pose), make sure you turn off plug and play support in bios before you try to boot it up! Secondly, make sure you have no other cd's/dvd's in other drives. This confused ubuntu to no end and halted the boot process
Thank's to all who helped it was much appreciated
