installing windows xp on a Imac model 4.1

I am trying to repair a windows xp install that was done on a Imac model 4.1 running osx 10.4.6. . I am aware that you need to run bootcamp to install the partition so that windows can be run on the mac. I inadvertently deleted the old install on the mac during a standard windows install booting from the disk deleting the partition then reformatting and copying the files. This has not worked it is missing certain system files. Now when I boot into the mac o/s partition I no longer see the ntfs partition. I tried to open bootcamp version 1.3 beta and it tells me that it has expired. I have searched the apple site on how to upgrade your bootcamp from a beta version but it only talks about how to do it with the working windows partition. How can I get a working copy of bootcamp back on this mac

Thank you but that site takes you to the apple download site that lets you download all the upgrades that will not open on a mac because they are exe files. and if you follow the download now button and look at the page it brings up in the left pane you will see the upgrade your beta version link. If you follow that you will see the problem I am faced with. You need to restart the computer into the windows partition. I can't the windows partition is gone

Can you see the partition NTFS partition when using the Apple Disk Utility?  You should still be able to see it there as it is a physical part of your computer's hard drive.

If you can see it there then now you need to get bootcamp.  Do you have your OS X installer media? If so, you can bust open the DVD and grab the app.

I can see it it is an unknown drive part. and yes I do have the disks. But bootcamp is allready installed but unusable due to the beta version has expired. My thoughts are that if I reinstall the mac o/s I will be reinstalling bootcamp with a new expiration clock. would this be correct?
Try setting your clock back to before Sept. 2007, run Boot Camp , set the clock back to normal after all done.

I ended up reinstalling the o/s thinking this would work. It did not. What you suggested has let me open it now but it wants me to update me boot firmware how do I do that with a mac?
Try running software update and see if there is a firmware update. If so, let it update. If software update does not find anything, try the directions here
You may want to change your clock back to normal time before trying to update. Change it back to earlier date to run bootcamp again.
