I installed windows 7 onto my second hdd (primary being windows 10) and after that windows 10 has vanished form the boot menu and from msconfig. not really sure how to add it back in. any suggestions?

Repair install is the easiest way. In general, dual boot is a bad idea because OSes are not made to like that sort of situation.
