EFI partition on usb-stick: Win10 not able to remove it with the diskmanager

Written by  on September 5, 2019 

Regular formatting/diskmanager can not handle it.
Additional tools were not available/allowed to install.

So the trick was to use “diskpart” (CMD ..):

  • then “list disk”
  • “select disk1” (or the one medium which contains the partition(s))
  • “clean”
  • confirm the error

Then use a regular tool to create a new partition.
