Okay so I built my first pc a couple weeks ago. It worked on very first start up, haven't had so much as a hiccup out of it since. Suddenly it hits me with a "Reboot and select proper boot device or insert boot media in selected Boot device and press a key." message on startup. I do hours of trouble shooting, changing Boot Discs and all kinds of things, nothing works. So I figure my only option is to reformat the disc. Reformatted it, but now windows is saying it cannot be installed to the disc (I only have 1 btw, a SSD device that again, has worked perfectly up till now since it's very first start up) because it's of the GPT partition style. Even though it worked just fine this morning when I powered it on. Wtf is going on? Is the SSD just defective?
