Can I Partition My Mac Drive After Installing Windows Through Bootcamp?

Hoping someone can help as I cannot find a straight answer on this, perhaps I am doing something wrong? I wanted to install Windows XP on my iMac. I previously had partitioned my Mac drives. I backed everything on these drives to my external and blew the partitions away creating my one Mac drive again.

I then ran Bootcamp, created a partition and installed XP. Everything was fine. I then partitioned my main drive and got the warning message about Bootcamp maybe not working afterwards. So I finished partitioning my Mac drive as I wanted and now I don't have the option of booting into XP through Bootcamp. When I try it just shows the Mac drive as my only boot option. I see the XP Bootcamp drive in the System Preferences startup disk area, but I assume I did something to the partition once I partitioned my Mac drives.

I don't mind installing it again, is there a way to partition for Bootcamp and then partitioning my Mac drive afterwards? Thanks if anyone can be of assistance.
