Gigabyte Reboot/Select Boot Drive ERROR Windows 10

[R1C3B0WL]

I turned on my PC today and there was the message: "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key."

I have no experience with BIOS or Boot drives at all and this has never happened to me for the past four years since I built my PC.

I have a GIGABYTE GA-X79-UP4 (or UD3) motherboard with BIOS uefi (idk), and I only have a WD 1TB Hard Drive.

I don't know what to do. Please help.

Thanks,

Additional info: I searched online and found some sources saying to insert Windows OS CD. I have Windows 10 Pro upgraded from Windows 8 Pro. If I insert a Windows 8 Pro OS CD, will it be able to detect the last update Windows 10 OS and restore my data?

Could be as simple as replacing a dead motherboard battery. Are you able to access the BIOS upon powering up the system (press F2 or DEL on most systems immediately after powering on the system)? If so, check the BIOS' date/time, is it correct? If so, the battery is okay and that your boot drive may be defective.

My BIOS is working, but I do not know how to reset it to default where it can detect my normal boot drive. I have a Gigabyte GA-X79-UP4.

You can go to the boot section and select the HDD (assuming it is still detected and is working properly).

My BIOS doesn't detect the HDD.

Check both the SATA data and power connections to ensure they are firmly attached at both ends (HDD and motherboard connection and the power connection from the PSU). Have you installed any new hardware since this problem occurred? If so, could just be a loose connection.
