I tried to turn on my PC and it came up with a black screen saying "Reboot and select proper boot device or insert boot media in selected boot device and press a key". I have checked and my boot priority is still my ssd with windows on and my pc is picking up both my drives fine, all the videos I've seen online to solve this are just people telling you to check that your boot priority is right which mine is. I then tried to do a fresh install of windows onto my boot drive and if i do the automatic one it says to reboot my PC without the windows USB in and then update, which i obviously can't do as windows won't boot. When I try to do the custom windows install it says that none of my drives are compatible to have windows installed onto them. I am using a gigabyte motherboard and have a samsung 850 evo ssd.
