If you are installing wsl on a Mac using bootcamp windows, and got this error, you should enter macOS first, and reboot to windows from ‘startup disk’ in ‘system preferences’ (instead of entering windows directly after pressing the power on button). After you have entered windows, go to task manager -> performance -> CPU, and make sure ‘virtualization’ is ‘on’.

1. Check if you have enabled VT virtualization: In “Task manager” -> “Performance” -> “CPU”, check if “virtualization” is on. If not, enter BIOS and enable this feature.
2. Check if corresponding windows features are enabled: Press win+Q and search for “enable or disable windows features”

dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart
# Enable "Virtual Machine Platform"
