Ok well your HP recovery is absolutely useless almost really. And you dont have to format the whole drive, just erase the Windows folder, program files, and your set. You can still keep your documents you just have to know how to make them work. Just casue your installing a new mobo dosent mean you have to format, but you DO have to reinstall Windows. If your that scared about it, just install new mobo, do a repair instalation on Windows, go into safe mode, take out old HP crap, go back into regular Windows, install new drivers, video drivers ect, your done.
