The problem would come up after I would burn a 32 bit iso using Startup
Disk Creator.
The usb stick with the 32 bit iso would never boot into the state where I
could "Try Ubuntu".
With dd the problem was solved. I could "Try Ubuntu" and/or "Install
Ubuntu".
Is there perhaps a way to compare 2 usb sticks, byte by byte, to see the
difference between the output of Startup Disk Creator and dd?
(Use a 32 bit iso.)
