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

    • 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. 🙂

      Thanks!

  3. In the Boot folder on my USB drive there is no etfs.com 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 🙂
