  2. Hello,
    thank you for this tutorial, it’s great! But I have a question. When I click “Build” button, shows a following message:

    “Your image contains an ‘install.wim’ file in the ‘sources’ directory so I’m going to assume it’s an Operating System installation disc. Operation System installation discs typically use the ‘UDF’ file system, not ‘ISO9660 + UDF’ as you have selected. Would you like me to adjust the setting for you?”

    What should I choose?

  5. Hello Amir,

    I’ve got a USB bootable key which is not Windows based so I cannot find any .com files within the key.
