We recommend performing Windows® 10 installations enabling UEFI with a GUID Partition Table (GPT).

Some features may not be available if you use the Master Boot Record (MBR) style partition table. System acceleration with Intel® Optane™ memory is not available when using MBR.

  • We highly recommended performing a backup of your data. If you have a second disk drive with enough available capacity, you can create a system image and recover the full installation as it was before you started this procedure.
