hello I have just build a new gaming pc(my first build so im a a noob) and when I have tried to boot for the past day it is saying that i need to select a new media to boot from!! It was fine for about a day after I finished building then this. I was able to play planetside 2 and metro: last light when i had it working. I have tried other people's solutions but none have worked. my specific propblem is I had two hardrives i ws going to put in raid but the drivers were just being a pain so i decided to just use one as a steam drive and another as my os and programs. I had windows 7 installed on the hard drive i was not using as a boot drive so to use it as a data drive i used a software program so erase to partitions(sorry i don't really remember the program i used) after this i installed steam ect.(rebooted a couple times which worked) and a couple of hours later windows wanted me to restart or an update so I did and when it was booting back up the message "reboot and select proper boot device or insert media in selected boot device and press a key". pls help!
