Installing XP on a relatively new computer is often a challenge and one that may prove futile. One problem, but not the only one, is the probable lack of drivers
. The XP CD certainly won't have them as it was created years before your computer. The chances are quite high that the computer manufacturer won't have them either. Most manufacturers find it difficult to justify the considerable effort required to write drivers for what is essentially an obsolete OS.
If you really must run XP it best to do so on a virtual machine. This will be much easier. And as you have Windows 7 ultimate you can use XP mode with no added cost.
If you must dual boot be sure to check for driver
