Windows 10: I'm dual booting two windows 10, bootgmr issue

Basically, a year ago I had only 1TB HDD, that had a Windows 10 on it, after some time, I bought 250GB SSD and installed Windows 10 on it as well, in order to keep my important files, I didn't format my old HDD and that's why I'm now dual booting two Windows 10, what I want to do is to get rid of the Windows 10 on the old HDD (at least by unplugging it from my PC)

I tried doing that, but I would get this error as shown on the screenshot: https://i.imgur.com/9weoQ9E.png

When I plug HDD back in, everything works fine, the thing is, I have "bootgmr.sys" file on both of my windows 10, (HDD + SSD), so I don't know what to do, I think my "bootgmr.sys" file is corrupted on my SSD, and my system doesn't recognize it, so I would need to either rebuild it using some software such as EasyBCD or something else, or going into msconfig and removing HDD's Windows 10 from there, I would like to hear your opinion, I pretty have same problem like this guy I want to move windows boot manager from HDD to SSD

Dual Booting with Windows 8.1


The procedure below will allow you to boot Windows separately or in dual boot configuration.
Here's what I recommend to do:

1. Disconnect the drive containing Windows 8.1
2. Install Windows 10 with one drive connected.
3. After step 2, reconnect the drive containing Windows 8.1
4. Boot up Windows 8.1. Open disk management and take a note of the drive letter of Windows 10 OS.
   NOTE: if you boot up Windows 10, then take a note of Windows 8.1 drive letter
5. Open Admin command prompt and type: bcdboot X:\windows where X: is the drive letter of Windows 10 (Windows 8.1 if you boot from Windows 10 in step 4)
6. Reboot the PC. You should have a dual boot screen.

NOTE: To break off the dual boot setting, Win+R->msconfig->boot and delete the none default entry on the list.
