Reboot and Select proper BOOT device loop

[Hoosiers888]

So, I recently built a new computer to game on. I had a few problems, but I eventually fixed it and everything seems to be going.
I connected my monitor and it brought me to a screen that said, "Reboot and Select proper Boot device or Insert Boot Media in selected boot device and press a key."
Once I reboot, it takes me straight back to that screen. If I unplug either the SATA cable or the power from my HDD, it goes to the Bios screen, but saving and quitting only reopens the Bios.
I can't find where to select boot priority, and even if I could, there wouldn't be a hard drive to prioritize.
Any help is appreciated.
I have a Gigabyte B150M-D3H as my motherboard and a Seagate Desktop HDD for a hard drive.
Thanks in advance!

Could well be a failed hard drive. Seagates (especially the 3TB ones) have been seeing really crazy high failure rates lately. If the drive is stuck in a BSY state, the system will hang like that.

Try testing the drive connected as a secondary on another computer. If it hangs too, you've found the problem.

the computer cant find an operating system.

if the drive is new you will need to get an operating system to install.

if the drive was from an older computer you will have to back it up its data******before doing anything****** then reinstall the OS on it as you cant simply move a hard drive from one computer to another.

"reboot and select boot device...." does not mean the motherboard doesn't see the hard drive. it means there is no os to boot. I bet you have no cd drive installed and that why when you do unplug the hard dive there is no drives to boot the system so it just goes to the bios.
