Area 51 stuck in boot loop. Please help.

Hi guys,

I just installed the J560M motherboard in my Area 51.  When the boot screen comes up, it says BIOS A07 and then it continues to boot look with the repair windows/start normally option as this system had a different mobo/cpu installed earlier and the hdd still has all the setting from the previous setup.  How can I get out of this boot loop if I just want to reformat the hdd and re-install windows?

thanks for the help!
