I'm building a new computer (first time) and have put it together and everything seems to be working ok. However, when installing Windows 10 from a USB stick the Seagate HDD and the Crucial SSD can't be found by Windows. Also the Bios shows that the two inputs (0 and 1) are empty. The motherboard is the Gigabyte B150M-D3H.
I don't know how to solve this problem.
Im going to ask that question but when you plugged in the SATA cable did you plug in the power cables into the HDD and SSD from the power supply?
Does the hard drive make a spinning sound at any point?
