I sign into cmd with Admin authorization; Clean disk with diskpart. physdiskwrite
-u generic-pc-1.8.1 , get thru the disks, select disk, get passed the warning with "Y".
Then I get the message "Failed to open\\. \PhysicalDrive2 - existing".
I think I have figured it out; I need to add .img to the end of the downloaded file. I will give that a try. Thanks.
