Hi,

Welcome to Microsoft Q&A.

Please help check below questions so we can narrow down the issue.

1. Detail version of server 2016
2. What changes had been made before the issue started?
3. Is the problematic server a physical machine or virtual machine?
4. Where is the data stored? Is it in a hard disk?
5. When did the issue happen? Is there a bluescreen?

Troubleshooting Tips are as follow :

1. Force the machine to reboot --> keep pressing F8 --> into Advanced Boot Options --> select Safe Mode to see if you can access the system.
   If safe mode fails, try Last Known Good Configuration.
   

2) If first operations fail, we have to disable auto recovery and check the error message screen. Steps are as follow:

reboot again --> press F8 --> choose Repair Your Computer to boot into WinRE --> open Command Prompt

First use diskpart to find the partition on your system disk, then switch to that partition and then run the command
Bcdedit /set {default} advancedoptions on
Bcdedit /set {default} recoveryenabled No

After auto-repair mode is disabled, see if and what errors are reported when normal mode starts. Please take a picture of the error message screen.

3)You can also run startrep.exe and SFC.exe in command prompt
Go to x:\sources\recovery.
Run startrep.exe

Hope this answer will help you.

Best regards,
Molly

Hi,

Is the problematic server a physical machine or virtual machine?
What changes had been made before the issue started?( patch，hardware etc.)

Please try to enter into safe mode from advanced boot options .
If you can enter into the safemode， please try to perform a cleanboot:

You can also open Command Prompt and run the following command as admin to see if it will fix this issue：
