so i just finished my very first pc build, i knew the bios part was not going to be easy, but this is stressful, i have no idea what i am doing and i've watch videos even read posts on this site, nothing is helping me and i honestly am ready to give up on it. So i guess my "problem" is even after i select my boot device, being my cd/dvd optimal, i still get the "reboot and select proper boot device or insert boot media in selected boot device and press a key" even after i insert my windows disk and hit a key, it just repeats itself every time i hit a key. this is my first post so i'm not even sure i'm posting in the right area, i just need some help.
