select disk #
You can delete all existing partitions from the USB stick with this command:

Mount the Windows 10 ISO and then copy all the files on the CD Image to the USB drive.
The UEFI bootable USB drive is ready. Connect it to the tablet. Boot into the BIOS. Under “Save & Exit” menu there is “Boot Override” menu, which should show your USB stick if UEFI detected it correctly. Select it to Boot from the USB and start the install.
