Install Windows for UEFI booting from E2B in MBR mode (using WinNTSetup)

If you have an E2B USB hard disk and you want to install Windows onto a UEFI-system, it can be a bit of a pain the make the .imgPTN file and get it working. Especially if you want to use SDI_CHOCO.

However, you can install Windows from an E2B USB drive using WinNTSetup by JFX. This way you do not need to modify the ISO or create a .imgPTN file or modify the boot.wim files, etc. to perform a UEFI\GPT installation. Also a WinHelper USB Flash drive is not required.


This means you can boot from a Win8/10 Windows Install or WinPE ISO and then use WinNTSetup to install Windows from any ISO on the E2B drive.

  • There is no need to UEFI-boot from the E2B USB drive
  • No modification of ISOs required
  • No .imgPTN file or modification of boot.wim is required
  • No WinHelper USB Flash drive required
  • You can use SDI_CHOCO XML files
There are many videos on YouTube about WinNTSetup, if you want to see it in action. You can even boot to one of the DLC WinPE ISOs which already contains WinNTSetup, instead of booting from a Windows Install ISO.

Tip: JFX has revised v3.8.7 Beta 4 so that you can run diskpart scripts using CTRL+SHIFT+D (see tools\diskpart folder).

For instructions see the WinNTSetup page on the E2B site here.
