I want to reinstall my windows 8.1 on an SSD, but i want to save my pictures and videos and stuff like that so i want to put it on my SSD. So right now my valuable stuff is on the SSD and the useless programs and games and the OS is still on the HDD. Now i want to reset my HDD and when that resets will i have no OS or will i have Windows 8.1 on the HDD? That is the 1st question. And the second one is if the OS is deleted and i install 8.1 on the SSD will the videos still remain there or not?
