Hi,

Thank you for the reply.

This problem might be caused due to various reasons:

  • Application conflict.
  •  Driver conflict. 

 We suggest you to do a custom install of Windows of Windows 10 on the PC.

Download Windows 10 Technical Preview ISO from the below link and reinstall the PC with Windows 10 Technical Preview:

Thank you for pointing this out, I marked my my system partition active in the Storage section of Computer Management and the upgrade now continues. I had obvously forgotten to activate the partion in an SSD upgrade of the computer.
