Windows 10: Invisible Boot Manager on Multi OS system.

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.

 

Hi,

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: bcdboot 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.

 

@NavyLCDR
Oh man. Read the answer carefully before challenge. X just represents a drive such as E:, F: etc... not the X from booting the recovery.

 

Hi,

From an elevetated prompt type the following command to get back a GUI boot menu:

bcdedit /set {default} bootmenupolicy standard

It doesn't matter what drive letter you put in there, @topgundcp. It still is not a valid option of bcdedit to just put a foldername after the command:
Code: C:\Windows\system32>bcdedit C:\Windows The specified command line is not valid. Run "bcdedit /?" for command line assistance. C:\Windows\system32>[/quote] You are confusing the command bcdedit with bcdboot - it is a valid option of bcdboot to put a folder name pointing to a Windows folder of bcdboot. But not bcdedit.

 

Nothing has worked so far. Thanks though.

 

Hi,

Can you post a screenshot of your bcdstore ? Open an elevated command prompt and type bcdedit then printscreen and save it in MSPaint as a png image.
Upload it here so others can have a look at it.
That is assuming the problem is you getting a textual (legacy) bootmenu and not a graphical one as you posted an image of.

Hi,

Thanks for posting that. Unfortunately I can not see anything wrong with it.
Strange how it does not load the GUI bootmenu.

Cheers, *Wink

 

@NavyLCDR
OK. That's correct. I meant bcdboot. That was a typo on my part, of course no such option for bcdedit.

However, boot into Windows 7 and use:
From admin command: bcdboot X:\Windows should fix the problem (X is any letter assigned to Windows 10)
