I'm dual booting two windows 10, bootgmr issue

K. I thought the command would automatically set the partition as active. That should be all you have to do now.

Right click on the C: partition in disk management and look for the option to set it as active. OR open command prompt (admin) again and run:

Code:

diskpart
Select disk 1
Select part 1
Active
Exit
Exit

That should complete it for you.

I do have option to mark my SSD's C: partition as active, as shown on this screenshot: https://i.imgur.com/dFNQCzB.png

My question is, after I do it, is the "System" still going to be on the HDD's partition?

I found this somewhere https://i.imgur.com/AuIH5bX.png

Use the disk part commands. It will not affect the HDD in any way. It will only make the SSD bookable. After get the SSD to boot by itself, then we deal with the HDD.

According to your screenshot, the option IS there in disk management. Look again, "Mark Partition As Active"

That's what you want to do, it won't affect the HDD

What do you mean by "After get the SSD to boot by itself"

I will mark my SSD's C: partition as Active then through the Disk Management, hopefully that I won't run into any problems such as "OS not found" or something similar to that.

When the computer boots from the SSD with the HDD disconnected, then we can deal with the HDD.

On this screenshot https://i.imgur.com/AuIH5bX.png, one guy said that on MBR disk (which is my case), the system reserved partition is required to be active, the thing is that I don't have the "System Reserved" partition on my SSD, does that matter or not?

Nope.

Nope.

After I mark it as Active, should I unplug my HDD to test will it boot without it? Also can it go wrong and should I backup my files or something?

Unplug the HDD to test it. Nothing is affected by this change other than making the SSD bootable.

Alright, tomorrow I will mark my SSD's C: partition active then, and inform you about the outcome.
