With so little information it is difficult to give a definitive answer. OK
you've got 200 professional, so one assumes you are upgrading? Tell us what
happens. The more details you give the more likely you are of getting a
reply with a solution.
Do you have the original Windows 2000 CD and product number? Have you tried
installing XP from scratch, i.e., slipping the XP CD into the CD-ROM and
rebooting the PC? Installation should proceed and then, at soem point, you
will be asked to insert the Windows 2000 CD to prove you are eligible for
the upgrade and then Xp should continue to install.
