How to run 2 copies of Windows 10 on your computer? (2018 September update)

This article needs more work!

It seems the latest version of Windows 10 and its update does not like multiple copies of Windows 10 running on the same computer.

When restoring a Windows 10 NEW image to C:\ and fixing boot to have only 1 Boot entry in Macrium Reflect only, saving to our Plextor M.2 disk. Computer works fine.

Attempt 3:20pm, to create Windows 10 2nd installation on D:

  1. On Windows 10, C:\ , I clone the same image to D:\ using drag and drop in Macrium Reflect 7.1. (12 mins)
  2. Using EasyBCD 2.3, I add D:\ into the boot menu.
  3. Restart my computer and heading into C:\ works fine.
  4. Restart my computer and heading into D:\ also works fine!

Conclusion: Seems like cloning the 2nd Windows needs to happen from the first copy of Windows, and the EasyBCD work should also be done right after, on that Windows, to work.

Therefore, the first DISK C:\ can be done from Macrium Reflect Rescue Disk, then fix the windows boot from Rescue Disk as well. After that, boot into the first C:\ Windows, and create the 2nd Windows installation using Steps 1-4 above.

Tip: Create a folder on C:\ with a unique name like, “I_AM_C”. So that when booting into the cloned 2nd Windows, you can differentiate the folders from File Explorer.
