I came across a youtube demo of how to install win 10 and etc on a new SSD hd. When it came to setup the SSD hd, he went to Disc management. He showed 2 existing hd's, one with C drive and the other for storage. Then he showed on D M. his new installed SSD hd. In order to continue with the installation, he clicked on each of his hd's and deleted the volume. So i gather this is another way to make sure that when your installing windows, you don't have to uplug the installed hd's, just delete the volume. He says your not actually deleting the hd, and after you install windows on the SSD, you can undo the deleted volumes. He doesn't say or show how to 'revive' those HD's, or possibly I did not understand. Does anyone here ever heard of this? I am desparate to try this, cause i have had bad luck installing win 10 the so called easy way with Media creation tool. Of course he was using the M C T with full updates for the installation of Win 10.
