Step 1: Create a set of Windows PE files on the technician PC.

  • Run the Deployment and Imaging Tools Environment as an administrator from the search box.
  • Run copype to create a working copy of the Windows PE files (copype amd64 C:\WinPE_amd64).

Step 2: Plug the USB drive into your technician PC.

If it’s not already open, run the Deployment and Imaging Tools Environment as an administrator.

Step 3: Type the following commands and hit Enter after each. Create two partitions on the USB drive and format them as FAT32 and NTFS respectively.

  • diskpart
  • list disk
  • select disk n (replace n with the specific disk number)
  • clean create partition primary size=2048
  • active
  • format fs=FAT32 quick label= “WinPE”
  • assign letter=P
  • create partition primary
  • format fs=NTFS quick label=”Data”
  • assign letter=O
  • exit

Step 4: Use MakeWinPEMedia with the /UFD option to format and install Windows PE to the USB flash drive, specifying the USB key’s drive letter. Simply put, run the command below to make your USB drive bootable.

P: refers to the drive letter of the USB drive you plugged in.

MakeWinPEMedia /UFD C:\WinPE_amd64 P:

After the command is executed, the boot Windows PE USB drive is ready. Then you can use it to either boot Validation OS from a USB drive or boot to WinPE to apply a Validation OS to a device’s hard drive. To learn more details, go to this page.
