Windows 10: I found a command prompt bug in Advanced settings where it flashes

Ok I found a Bug in advanced Settings where it flashes, and I was worried so I did a sfc /scannow and it found corrupted files but here is the thing a minute before I went into advanced settings I did a sfc and it did not find any integral violations So is this something I should be worried or can someone fix this bug I only use advanced settings in case of an emergency but Command prompt keeps flashing when I boot up advanced settings.

command prompt will not open in safe mode with command prompt

Would I just follow the same steps within safe mode after hooking up to the other system?

 

Installation media boots to command prompt

I've just booted from known working install media to see exactly what it does when booting. The sequence of events is...

1. Windows logo on a black screen
2. circling dots appear beneath the logo
3. light blue 'Please wait' screen with circling dots
4. a command prompt window (very briefly)
5. the initial Setup page appears

Do you see steps 1-3? If so, it appears you have stopped at step 4, suggesting that something on the disc cannot be read.

Does the disc boot properly in another machine? If so, try cleaning the laptop's drive lens then try booting from the disc again.

If not, make new install media with Microsoft's Media Creation Tool, either as a bootable USB, on an ISO that you can burn to another disc. At Step 8 in Option One of this tutorial you can choose between making a USB or an ISO.

No Command Prompt in Advanced Startup

I'm trying to use MBR2GPT in Windows 10 for my system disk so I can use UEFI, and I suppose I need to use command prompt in Advanced Startup.

But when I do Advanced Startup and go into Troubleshoot, the only option I can see is Startup Settings.

No Command Prompt, no System Restore, nothing, just Startup Settings.

So how can I get access to command prompt? Or can I just use MBR2GPT in cmd while running Windows 10?
