According to the documentation, startup disk creator will create Ubuntu startup disks. It seems to look for the Ubuntu tag in the disk type, and if you try to make a Debian disk, it will fail with that error message "Invalid version string 'GNU/LINUX'". This is the type for a Debian ISO, but not for Ubuntu.
My solution is to use UNetBootin, especially for non-Ubuntu disks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/722019 Title: Failed to install the bootloader To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/usb-creator/+bug/722019/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
