I have the same problem with super_grub2_disk_hybrid_2.01-beta3.iso (http://goo.gl/bC04rC) and clonezilla-live-20140114-saucy-i386.iso (http://goo.gl/SsVjhv).
I run the creator from command line and this is what I have got: DEBUG:root:Backend told to add: /home/auser/Files/Disk 04/Linux/super_grub2_disk_hybrid_2.01-beta3.iso DEBUG:root:['isoinfo', '-J', '-i', '/home/auser/Files/Disk 04/Linux/super_grub2_disk_hybrid_2.01-beta3.iso', '-x', '/.disk/info'] isoinfo: Unable to find Joliet SVD ERROR:root:Could not extract .disk/info. I am not sure whether that missing file (provided that's actually missing) is a showstopper for the creator to work. Anyway, previously I never had such problems: any real ISO file could be used with the KDE usb creator. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/705353 Title: usb-creator doesn't accept iso file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/usb-creator/+bug/705353/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
