    @Mystere
    Sorry but did you read the steps I posted ?. What do you mean by: It may boot up, but won't be EFI ? How else does it boot up with a GPT disk ? Here's the screen shot

    You have an EFI partition. If you were originally an MBR, then it won't have created an EFI. My point is, simply changing to GPT is not enough.

    What you say is true enough. However, creating the EFI partition is covered in his step number 3.

    1. Download and install Macrium Reflect Free and create a backup image of your current MBR Windows 10 to an external HD. (You should anyway before modifying any Windows partitions in case something goes wrong)
    2. Create a bootable Macrium Rescue disk on a USB/DVD (from Macrium application, click on the first icon on the top left)
    3. Next, wipe out the disk and install a fresh copy of Windows 10 using GPT partition scheme. The installation should create all the needed partitions and C drive. No need to run updates because you're going to overwrite the C drive with the C drive from the backup.
    4. Next you'd want to ovewrite the C partition from fresh install with the C partition from the backup image.
      Boot up from the Rescue Image and follow the steps in the video as shown below and you're done.

    Your method did not work for me when converting my current Windows 8 MBR disk, however I did come out knowing how to create Windows PE 5.0 Rescue disk using Macrium after reading your post though.
