I recently built a new PC: MSI z170a M5 Motherboard, GTX 1070 GPU, Intel I5 6600, 2 8GB ddr4 ram, and 2 HDDs (that I was using in my previous PC)

I can boot to BIOS and Boot settings but when I try to boot with either of my HDDs it says "an operating system can't be found. Please disconnect all Hard Drives that do not contain an operating system".

I wasn't sure what to do so I followed the steps on another computer to put the windows 10 install file on a usb. I boot my PC to the usb, the screen will stay on the blue WIndows icon for 2-3 minutes then the comp will blue screen and say critical boot error. One of the errors i remember it saying was CL.DLL is what failed.

I have tried various types of suggestions to fix this since i have no clue why its happening. I have cleared CMOS, Reset BIOS settings, Tried booting with 1 HDD, tried booting with 1 stick of RAM. I have been reading some possible answers and some people are saying it could be a virus on the HardDrives. Does anyone know why this is happenening?
