Windows 10: Secondary drive marked as System + Black screen

Hello,
I have similar problem to these two:

a secondary drive marked as system drive? Solved - Windows 7 Help Forums
BOOTMGR is on the wrong drive? Partition marked as SYSTEM Solved - Windows 7 Help Forums

I've read those posts but I'm not sure about the instructions and I need help specifically with my case.
I'm a little bit worried about data loss because there are some info saying that those changes can make some issues.


Also I have additional problem that can be connected to this?

While I'm turning on my PC(monitor is ON) there's black screen
There's no screen until Windows login screen (There's sound of GPU fans spin and then Windows login screen is showing up)
Monitor is connected to the GPU.

But while I'm connecting monitor to the motherboard hdmi everything works great. I can see everything from the start to the windows login screen.


Thank You.

:)

Installing the Windows 10 1909 Update causes my secondary hard drive to not be recognized.

• Secondary drive not visible in disk manager

Steps to replicate issue:

Steps to resolve issue:

Since updates can only be delayed for so long, an actual fix would be appreciated.

 

System restore and secondary drives


So my setup. I have 2 drives in my computer an SSD and HDD. The SSD came shipped with my computer and I installed the HDD as a secondary drive. I've been using it as storage for all my pictures music etc. I've also installed a couple programs on there. My question is if I do a system restore can I do it without wiping out the secondary drive? How would I go about doing it? Step by step. What would happen to the program's installed on there after the restore?

Thank you.
