Can install Windows 10 due to insuffient space on a 500GB partition

@tecknot, you can't trust on Windows Disk Manager. It doesn't show MSR partition and the EFI partition it says it is 100% free when its not.
A disk manager you can trust is MiniTool partition manager

Hi Megahertz,

I guess I will reluctantly download MPM. Thanks.

Kind regards,

I wonder why such investigation is conducted on a brand new recovery partition when an EFI System and a Microsoft Reserved Partition in the middle of the disk are the real curiosity. Not to mention a 15 MB primary partition formerly known as MSR.

The intention was to delete partition 1 as it was preventing win 10 to install and then recreate a new EFI and MSR on the unalloacated space at the beginning of the drive.
It did create a new EFI partition on the unallocated space probably when Win 10 was installed and not by the WinPE commands that should create at the beginning of the drive.

The intention does not count. The knowledge and the result counts. And the result shows exactly that, what I expected.

And with some basic math you find that the result should be 616,327876953125 MB
