Windows 10 Black Screen, No Cursor

Hi,

Welcome to Microsoft Community and thank you for your interest in Windows 10.

Please follow the below suggestion and check if that helps.

If you see the black screen only
after sign-in and you can see a mouse cursor:

• While at the black screen, try using CTRL+SHIFT+ESC to start Task Manager.
  
• If it becomes visible, try finding LockAppHost.exe on the Details tab and ending the task.
  

If this resolves the black screen, use corruption resolution steps.

Perform SFC scan.

System File Checker is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files. This article describes how to run the System File Checker tool (SFC.exe) to scan your system
files and to repair missing or corrupted system files in Windows.

Use the System File Checker tool to repair missing or corrupted system files

Use the System File Checker tool to repair missing or corrupted system files ( Applies to Windows 10 as well).

I would also suggest you to run the System update readiness command. It detects incorrect manifests, cabinets or registry data, it may replace the incorrect data with corrected version available. Follow the steps.

• Press Windows key + X.
• Click command prompt (Run as administrator).
• In the Administrator: Command Prompt window, type the following commands. Press
  Enter key after each command:
  • DISM.exe /Online /Cleanup-image /Scanhealth
  • DISM.exe /Online /Cleanup-image /Restorehealth

To close the Administrator: Command prompt window, type
Exit, and then press Enter.



Hope this information was helpful and do let us know if you need further assistance. We will be glad to assist.

 

Windows 10 Black Screen During Install


Hey guys,


I was installing windows 10 (8.1 before) on my Dell inspiron 15 7000 series (7537), and it progressed to restarting after the installing drivers step, but after the restart and going through the dell startup screen, everything went black. The HDD light is stuck on and not flickering like it normally does. There is no cursor or anything on the screen, it's just black. I waited for an hour and nothing changed, so I thought maybe it was frozen, so I restarted the computer via hard reset, which took it to a "attempting to recover update" screen, but after a few seconds on that screen it went immediately back to the black screen.
Its been about 30 min since that hard restart and its still black, HDD light still on, and nothing seems to be happening. Does anyone have any solutions to this???
Thanks!
