Windows 10: 'Choose an operating system' screen shows no options

I've install windows 10 dual booting with 7 so i can use my old laptop with work networks, but after setup and reboot I get to a blue screen that says choose an operating system, but the unfinished windows 10 and my perfectly working 7 install don't show up. Instead the screen is just blank see attached picture. If I click change defaults or choose other options, the timer and default OS both say '%1'. Is there a way I can recover my windows install without erashing the hard drive? Troubleshoot menu also turns out blankI should probably mention that I'm using Tiny10 because 22h2 is too b

How to bypass "Choose an operating system" blue screen?

Thanks, Malok, I think I see where the problem lies. The OS listed on the Boot tab is just "Windows 10"

But the top OS on the Selection Screen at Bootup is listed as "Windows 10 from volume 3"

I'm not sure, but I believe that whichever option I chose at the previous bootup, moves to the top position on a subsequent boot up. So I'll try switching to the bottom option and see what happens.

 

' choose an operation system to start"

Hi Bob,

To better assist you, do let us the complete message that you receive.

Sometimes, this could be due to two operating system installed in your computer. Just to make sure this is not the case, I suggest you to try the steps below:

1. Press Windows key + R.

2. Type msconfig and press enter.

3. Click the "boot" tab and check if there are any other operating system listed.

4. In addition, change the timeout time to 3 seconds(default)

Let us know the result, we will be glad to help if you need further assistance.

 

After “Choose an Operating System” goes Black Screen (Windows 10)

None of that worked for me. I only get "Choosing an operating system" from Windows 10 Home and then puts the screen between black and white. I can not use anything. Will I have to change the hard drive completely?
