Invisible Boot Manager on Multi OS system.

I would try:

bcdboot C:\Windows /s F: /f ALL

Hi,

Nope, that will create a Bios and UEFI boot record for drive letter F:\ .
From what I gather of what TS states he has a graphics resolution problem making the boot menu screen look all black. Or does he mean it's black and white and he wants the blue screen back ?
If so, that can be fixed but I'll await his response.

Cheers,

Respectfully, no it won't. It will create a boot record for C:\Windows on the BCD store which is currently located on his F: drive.

the /s F: switch only tells the system on which drive to create the boot files.

My boot menu should look like this.

However, the screen is all black, totally blank with no cursor. The win10 win7 buttons are still present. I can still select either one with arrow keys and the enter button to boot to either os. I suspect its some kind of driver issue, but how to solve it with the drivers installed on the system is part of the problem.


When my system hung and changed the resolution settings on their own it showed up. Problem with the eyefinity is it puts my windows button all the way onto the left monitor and my clock all the way to the right and streches any open windows to fit all three. I've rolled back drivers and installed new and neither fixes this. Creator's update did something and I don't know what.

My only way to get the menu back is to use windows graphics drivers or change to eyefinity settings.

Yes, it does sound like your boot menu entries are probably correct. It's over my head how to fix what appears to be a display driver issue.

What are you using eyeinfinty for? It's only used for 2 or more monitors. When I had and AMD card I only used eyeinfinty for gaming to span the game across all 3 monitors. After I was done gaming I disabled eyeinfinity.

How many monitors do you use? Since the CU/FCU have you uninstalled your GPU driver and then downloaded the latest version and installed it?

I have 3 monitors. AMD settings allow for eyefinity during game launch and disables after game exit. I have completely uninstalled restart reinstalled and installed new.

Ok, I see. Did not realize TS's BCD store is actually on drive F: .Sorry about that.

Has nothing to do with driver. Your advice is incorrect !!!

@SilntExecutionr

Your disk layout is not configured correctly, there's no "System Reserved partition", might cause problem with future update. Currently Windows 7 is booted from Winload.exe of Windows 7

Boot up Windows 7. Open admin command then run: bcdedit X:\Windows where X is the drive letter of Windows 10
You should get the GUI interface back.

You're advice would be equally incorrect, my friend. X:\Windows is not a valid option for the bcdedit command.
