Dual boot vista

Hello,
tried to install windows xp professional on my lenovo thinkcentre system pre loaded with windows vista business. I made my first bootable device as cd rom and the second as HDD. The system boots from the cd and shows that setup is loading the files. And immediately after that a blue screen pops up and says a message. I'm not able to move further. the message states something like this setup could not continue if this is the first time...........chect for viruses on ur computer......run chkdsk-f....and so on....
So please somebody help me out in solving out this issue.How can I install windows.Is it possible. I am waiting for ur reply.....
Thanks a lot in advance.
