Windows stuck in automatic repair; Can't access BIOS/ boot menu

I've changed the boot order through both BIOS and the boot manager, as my original post stated. Neither did anything, but both were functional in the past. Neither listed the windows boot manager, either. Previously, it would boot just as expected whenever
other media was set as the first option, so I'm pretty sure there are no issues there.

As my original post suggested, I've already tried out the steps you gave. I've gone through all the options listed in the boot menu, UEFI or not.

My BIOS and boot menu settings were at their defaults when all of this started, so that's been tried already, if those are what you're referring to.

 

Boot Emergency!

No it doesnt show. Only my OS drive.

Its there and it says it running and normal.

Anyway I just had the same boot problem on reboot. Everything was fine 10 minutes ago. Now it wont boot without my manually selecting the drive.

 

No startup boot menu

Hello Kimoefat,

Thank you for posting your concern in Microsoft Community and welcome to the Windows 10 Family.

As an initial recommendation, I would suggest you to access the System configuration utility and check if the Operating System installation path for Ubuntu exists. To do so, follow the below steps.

• Type msconfig in the search bar and select System Configuration from the search results.
• Select the boot tab in the System configuration console to check if the installation path for Ubuntu exists.

If it exists, next logical step is to check if the boot menu time out has been set to 0, which results in Boot menu not showing up.

The boot menu time-out determines how long the boot menu is displayed before the default boot entry is loaded. It is calibrated in seconds. To change the boot menu time-out, use the Bootcfg
/timeout switch. Valid values are from 0 through 999. You cannot use Bootcfg to set an indefinite time-out.

You can run the following Run command line to set the boot menu time-out accordingly. To do so, follow the below steps.

• 
  Press Windows key + X, select
  Command prompt (Admin) to bring up elevated Command prompt
  
• 
  Type in the following command: bootcfg /timeout 10
  
  timeout 10 will set the time frame to 10 seconds
  

However, if the Boot path for Ubuntu does not exist in the boot menu of System Configuration utility, I would suggest you to check if the Ubuntu is overridden by the Windows installation or if the Ubuntu installation files are corrupted.

Hope the above information is helpful. If you need further information, feel free to write to us and we would be happy to help you.

Thank You.
