So recently an older HDD of mine died after sometime. I bought a new one and am having trouble getting the PC to notice my Windows disc inside. This is my first time ever downloading windows onto a drive. Not sure if it matter, but my Mobo is a MSI Gaming m5 Z170A and my CPU is a 6600k. I nearby tech place gave me a windows 10 CD since I had a registration key already. Whenever I turn the PC one with the disc, it takes me to a black screen and tells me to "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key." Not sure what I'm supposed to do. I've changed my boot order so that the CD drive is 1st and I still get the same error. The HDD is fine, i had it checked out at a local computer repair shop. Any tips would be highly appreciated!
