Not my problem, but one I have noticed many, many times lately on these pages. So many people report 'unable to boot from install CD' or DVD, despite having the boot order correct. Can some experienced repair technician throw light on what is going on - are CD/DVD devices becoming quite quickly unable to support booting? And what may be the cause? Is there some change in recent motherboards, is XP/Vista/Win7 sending out updates which interfere with motherboard drivers? Do devices simply fail quite quicky these days? .... or what?
