  1. Basically, Windows 7 supports boot file whereas windows 10 support EFI file. So select according to your Operating system.

    • Do you have to change the sector to load number when you chose an EFI file instead of the ETFSBOOT.COM file? I am trying to create an ISO from a bootable Windows 11 USB drive and could not get the ISO to boot after it’s created.

      Excellent tutorial, btw. Thanks!

      • Hello Joe,

        If you are converting Windows 11 USB to an ISO file, then just go to the Boot folder, and then you will find an etfsboot file which you have to select as Boot Image, after that change the Sectors To Load as 8. Once all these settings are done, just follow Step 4 mentioned above.

        Hope it helps 🙂

    • Hi Alexander,

      Yes, some antivirus detects it as a virus but it is truly safe and will not harm your machine & files. While downloading it, please turn off your antivirus & after installation you can turn it on. 🙂


  2. Thanks for sharing this information, maybe you could show how the “build” button looks like since is an ICON no text.

  3. In the Boot folder on my USB drive there is no but in \EFI\Boot there is bootx64.efi. Would I use the latter? Or which efi file?

    • Hello Tim,

      In that case, I would suggest you to re-download the ISO image file from the official website and then try. Because we have seen that due to some lost files the ISO image doesn’t boot properly.

      And if the issue still persists with the new ISO file, then check whether your boot settings are correctly configured or not.

      Hope it helps 🙂

  4. Doesnt seem to work – Windows 11 latest IMG burn

    I have no EFI or UEFI folder as they are on a separate partition on USB harddrive (SSD accessed through USB)

    seems like i have to do it in linux

  5. Does this work on other bootable USBs? I am trying to make a backup of my Revo Pro USB stick in case one of the PCs I am working on corrupts it.

  6. My Dell Recovery USB drive for Windows 10 Pro gave me a error when it ran;
    Directory depth exceeds ISO9660 limit of 8 levels.
    Name: ‘\sources\$OEM$\$$\OEM\Apps\DDD\Link\ANW\’
    Number of directory levels in path: 9
    Most directory levels in any path: 9
    Would you like to continue anyway?

    Of course I said Yes. When I checked to see what was in that folder and it only has a Alienware Digital Recovery shortcut. Since this isn’t an AW product I’m hopeful.

    • Hello Paul,

      Could you please describe to me more about the issue you are facing? Because we have used this process plenty of times for Windows 10 but I am not sure about that it works with Alienware product or not.

  7. Hello, I tryed with a Rufus-USB and it did not work, so am trying to create a bootable ISO for use under Hyper-V using an original Win11-ISO 22H2 from Microsoft as source, but with the configuration above it does not work too. Any tips?

    • Hi Jules,

      We have used the above steps for Windows 11 also and it worked perfectly fine. I think you have done some wrong settings, please check this comment and let me know if this worked for you or not.
