[SOLVED] "Reboot and select proper boot device" after taking GPU out and putting it back in

[Josh Bazely]

I recently bought the cooler Master vertical GPU mount. Computer worked fine before, decided to turn it off and install it and then this message came up when I put it back together. I then uninstalled the vertical mount and reinstalled the graphics card like normal and still got this message. I checked all the connections and unplugged everything and replugged it back in. And ideas?

If you go into your BIOS and check your boot order is your boot drive recognized?

Check if your SATA-cable to your hdd with your boot got loosened when you installed the mount

And also go to bios and check your boot order
