Quick update. I emailed support to query the price and they have very kindly provided me with a disk free of charge. The computer is back up and running and I am very happy.   Thanks Dell!
Hi,  Newbie here! I have an ageing (5 year old!) Dell 8300 desktop, and the hard disk is dying. I want to reinstall XP onto a new hard disk, but I have lost the 'restore disk' that came with the machine. I have the XP product license key stuck to the side of the computer. So I just had a quick live chat with tech support, and the cheapest they'd ship a replacement disk was £19! I don't mind paying fair P&P, but that's excessive! Have tech support given me correct information? I am in the UK so I guess things here may be different to the USA Thanks for your time, I did search before posting but didn't find a recent enough answer to know if it was still valid.
