How to troubleshoot for HDM:
Run RMB with administrator permissions.
Reinstall the RMB to the folder with admins permissions.

Using DISKPART to completely erase the disk helps in most cases.

(find your USB stick in list and remember its disk number)
select disk #
(your USB stick number)
clean

Non-standard USB sticks, for example so called Udisks which require special drivers. Solution: Use standards compliant USB medium.
Other USB chips with own drivers (USBest, usb2flashstorage) cannot be used as well. Solution: Use standards compliant USB medium.
A USB medium is formatted in GPT style. Solution: Convert medium to MBR, remove probably existing partition(s).
Customer: The matter has resolved itself. Medium was damaged. Two others worked seamlessly. Solution: Use undamaged USB medium.
A partition starting on physical sector 0 is already existing. The first partition should start on sector 2000 or at least 63 to allow enough space for the MBR (Master Boot Record) before the first partition. Without an MBR the drive cannot be set bootable. Solution: Remove existing partition(s).
