sorry this step is not clear to me.
1. copy all the iso to the stick
2. when the File (iso_filename.txt) ist empty the Machine is not reboot from the ISOStick
3. I load any iso file in ISO Manager and in the File (iso_filename.txt) this info is posted (/ADRIANE_KNOPPIX_V7.0.4CD-2012-08-20-DE.iso)
Now reboot the Machine from the ISOStick perfect. And I see all other ISO
this is the correct procedure ? or I do something wrong here
THX for your Help
