If you want "white gloves" then you will have pokupat a new license, which comes with the drive. Well, or some way to access (subscription) msdn then you can download desired image from the MS website, though it already other money...
In General, the license terms permit the installation of OEM (activation) only once (on one computer). That is, even if you install it on a new PC and keygen fit, activation will fail.
Though, probably, there is another way. If you know exactly which version (edition) WinXP fits your keygen, you can try to look for an oem drive without a license: a hammer, ebay (although hardly, if Windows Russian) or what organization (if familiar is) the drive will sell/give for symbolical money. Before XP (disk only) on softkey sold for little money, but it seems to be only for organizations, and now piggy there to be seen.
