Replacement hard drive

Help, I replaced me hard drive as the one in my system was bust so unable to make a recovery disc.
I replaced it with a new hard drive but have problems loading Windows 7 from the disc which is an upgrade.


The system was originally running XP, I do have an XP disc but it is also an upgrade, Is there anything I can do to get this up and running again, As is probably obvious, I am a bit of a novice in this field. Any help would be welcome.
