A Hypervisor Error in Windows 11 with VirtualBox usually happens because Hyper-V is enabled and conflicting with VirtualBox’s virtualization engine.
To fix it, try these steps:
First, disable Hyper-V and related features by going to Turn Windows features on or off and unchecking Hyper-V, Virtual Machine Platform, and Windows Hypervisor Platform, then restart your PC.
If the issue continues, open Command Prompt as Administrator and run:
bcdedit /set hypervisorlaunchtype off
Then restart again.
Also make sure hardware virtualization (Intel VT-x / AMD-V) is enabled in your BIOS/UEFI settings.
Finally, update to the latest version of VirtualBox, as newer versions handle Windows 11 better.
In most cases, turning off Hyper-V resolves the VirtualBox hypervisor error permanently.
