Hello,
Recently I changed over to Windows 10, first by adding a partition to my C: to try out and configure Windows 10. Now I want to make the new C: (101 GB at end) Windows 10 partition as Active and as System, but cannot figure out how to. See Disk Management setup below:
When I set to Active, the BIOS doesnt recognize the operating system, and I have to use diskpart at command prompt to recover.
