I've tried to create an bootable USB stick from a .raw file with Win32DiskImager. So far so bad, this program formatted 2 of my USB sticks as "Disk"s as seen on the captured Screenshot.
If I try to "mount" them via right click on "Disk 1" > Change Drive Letter and Paths my PC shows me the Error "The Operation failed to complete..." (please have a look on my screenshot)
Please help me, thank you!
