Now I'll introduce to you how to do it!
Prepare USBOOT 1.7. Use the USBoot v1.7 USB flash drive making tool to make your USB flash drive into a USB-HDD DOS bootable type. Note that when selecting the "Work Mode", you must choose the HDD mode, and it can be successfully made according to the tool's prompts. Download the USB-HDD-WinPE.rar compressed package (this will have a winpe system after doing this), and extract the files inside to the root directory of the USB flash drive. Note it's the root directory!
Use of the USB flash drive boot disk:
Insert the USB flash drive into the USB port (it's best to temporarily unplug other USB devices), restart the computer, and press the Del key to enter the BIOS setup at the system self-test interface.
Enter BIOS FEATURES SETUP, set Boot Sequence (boot order) to USB-HDD first. After setting, press ESC once, return to the BIOS main interface, select Save and Exit and press Enter to confirm and exit the BIOS setup. After the computer restarts, the main menu will appear.
If your motherboard can only boot in ZIP mode, operate as follows.
Use the USBoot v1.68 USB flash drive making tool to make your USB flash drive into a USB-ZIP DOS bootable type. Download the USB-HDD-WinPE.rar compressed package, extract the files inside to the root directory of the USB flash drive, and then replace the AUTOEXEC.BAT and MENU.LST two files in the ZIP mode folder with the same-named files in the root directory.
Insert the USB flash drive into the USB port, restart the computer, enter BIOS FEATURES SETUP, set Boot Sequence (boot order) to USB-ZIP first. After the computer restarts, the main menu will appear.
