While building a bootable USB thumb drive within the Boot Disk Creator you receive the following error:
The directory is not empty
So this message is not necessarily an error. This message does not mean there is a problem with the Boot Disk Creator. It is a message generated by Microsoft and revolves around which build of WinPE 10 that is being used.
Ghost Solution Suite 3.x
WinPE 10 release 1511
This issue occurs while using WinPE 10 build 1511. If you remove WinPE 10 build 1511 from our product and then add WinPE 10 build 1703 or higher this message will go away.
To add a new build of WinPE 10 to Ghost Solution Suite you must first remove the previous installation of the Microsoft ADK. This can be done through Add Remove Programs. Remove the Windows Assessment and Deployment Kit - Windows 10. You will then need to download and install build 1703 or newer from Microsoft.
How To remove WinPE 10 - Ghost Solution Suite:
To remote WinPE10 from Ghost Standard Tools you need to browse to C:\Program Files (x86)\Symantec\Ghost\bootwiz\Platforms\ and then follow the steps above starting at Step 4.
