original CD.I want to istall WinXP on my system.How can I get my copy of WinXP ?

If it is lost, I think you have to buy a new CD. It should have a recovery partition on it though? Use that?

Ask Lenovo for recovery discs for your ThinkCentre. You may have to pay a little bit of money, but they should send you the discs.
