You only have one primary partition, and it's a Linux file system.
Windows XP requires it's boot files in a primary partition. The best way to avoid this problem is to install Windows first, or create 2 or 3 primary partitions and install either all of Windows in a primary, or format a small primary with Windows file system and the Windows installer will see it and use it for the boot files, then you'll have to reconfigure grub...if that's your boot loader.

Keep in mind, in mechanical hard drives, due to zone bit recording, the first partition is the fastest partition, optimally this is where you should consider putting the operating system that can benefit most from this partition's advantage.
