So... I just built a new pc
And my ssd hdd are detected in my bios
I was using usb flash drive to install win os 7 enterprise retail.
While I was installing I got the message as stated on the title
Did you put USB stick to USB 3.0 on your PC?
If yes, then it's a reason why you received this message.
Try to put into usb 2.0, and repeat process.
