If you experience a black screen showing only the cursor on Windows 11, one helpful tip I discovered is using the keyboard shortcut Win + Ctrl + Shift + B simultaneously. This refreshes the GPU and often resolves the display freeze. Another approach is creating a bootable USB media to repair your system's boot records. I selected the 'Make Bootable Media' option from tools, chose my USB device, then changed the boot order in BIOS to prioritize it. Rebuilding the Master Boot Record (MBR) through this method fixed deeper system corruption that caused the black screen. From my experience, having reliable bootable recovery media on hand can prevent long downtime if the problem recurs. Also, verifying BIOS settings and updating GPU drivers helped me avoid future display glitches. These straightforward steps offer practical fixes to get your Windows 11 desktop back without losing data or reinstalling the OS.
