Notice:
The Set active option is only available when your USB flash drive partition style is Primary. You might need to convert the logical partition to primary partition if marking the partition as active fails at this step.

Part 2. Copy Windows Setup to the USB flash drive

Use File Explorer to copy and paste the entire contents of the Windows product DVD or ISO to the USB flash drive.

Tip
Due to the limitation of the FAT32  file system, you will not be able to copy the file larger than 4GB to FAT32 USB flash drive, but the Windows 10 image file happens to exceed the FAT32 file size limit of 4GB. You can troubleshoot the file copy failure like this.

Step 1. Copy everything except the Windows image file (sources\install.wim) to the USB drive using this command, where D: is the mounted ISO and E: is the USB flash drive.)

robocopy D: E: /s /max:3800000000

Step 2. Split the Windows image file into smaller files, and put the smaller files onto the USB drive:

Dism /Split-Image /ImageFile:D:\sources\install.wim /SWMFile:E:\sources\install.swm /FileSize:3800

Part 3. Install Windows 10 from the USB Flash Drive on Your New PC

  • Connect the USB flash drive to a new PC.
  • Turn on the PC and press the key that opens the boot-device selection menu for the computer, such as the Esc/F10/F12 keys. Select the option that boots the PC from the USB flash drive.
  • Windows Setup starts. Follow the instructions to install Windows 10.
  • Remove the USB flash drive.

Sometimes, it'll be greater to install Windows 10 on an external hard drive. By this way, you can use your own customized Windows 10 operating system wherever you go.
