Certainly more correct sequence is to install the Windows version of the younger to the older. But what do you do if Windows 7 is already installed, and you need to install Windows XP.

When you install an earlier version of the Windows installation program overwrites all data in the master boot record (MBR), boot sector, and the boot files. Earlier versions of Windows are not compatible with the new method of downloading a new system. In particular, Windows 7 uses a new BCD store. This store contains a boot menu and all the information about the operating systems that are installed on your computer. Consequently, the Boot.ini file from an earlier version of the Windows operating system can not be used to run it.
Installing Windows XP does not particularly stand out and would dwell on this question makes no sense. Naturally when you install, you must specify a partition, which was prepared in advance.
After installing the Windows XP operating system no choice at startup or, respectively, the ability to download Windows 7 will not.
