So, I know that you need to reinstall OS after replacing parts like motherboard. I replaced mine long time ago. I managed to do it somehow, I think it was some HP program I launched somehow. My version is preinstalled. I have this Recovery thing in my hard drive. Im not sure should I use it and should I launch it from bios or should I launch the HP factory reset/OS reinstall thing wich I dont remember how to. Any ideas?
when turning on pc rapidly press f10 it or f11 it is used in most hp for factory reset
if you have done this before with the new motherboard and everything worked well do it again because it installs all drivers
