I wanted to install Windows on my other hard drive with Rufus by using Windows10 ISO and without using any external USB/CD/DVD.
So I plugged in the other drive to my motherboard and I can see the drive on my PC, as well as DiskManager.
However, Rufus doesn't show it..?
How to make Rufus show internal hard drives?
ALT+F
in Rufus to enable fixed internal storage (hard drives).
