I wanted to clean install wiping the hard disk (removing and recreating Windows partitions). In addition, to get more storage space I had removed factory restore partition and extended C: drive to that freed space. I had no SD cards available and even if I had found one, Windows installation can't be booted from SD card.
Due my own actions the only USB port was broken, not recognizing any USB flash drives. Sometime ago I had an interesting dilemma: A Windows tablet simply refused to upgrade from Windows 10 version 1607, the Anniversary Update.
