Worked with UNetbootin to make bootable USB to install new OS or rescue OS several times happily, but didn’t work anymore for OpenSuse. UNetbootin silently could not successfully Extracting and Copying Files (i.e. Step 2).
Use MagicDisc to mount the OpenSuse ISO file
Copy the content of the ISO to a temp directory
Use All FreeISO Creator to create ISO
- Windows 7
- MagicDisc 2.7 build 106
- All FreeISO Creator 3.1.9
Seems that funny to extract the ISO and wrap it again, but found no other way to make the bootable USB.
