If you get this error, chances are you trying to get Linux running in a VM using Virtual Box on Windows. If you see this follow these steps:
- VT-x is not enabled in the BIOS – Restart your computer and select the key required to enter your bios settings. Typically ENTER or F12 or something like that.
- Hyper-V virtualization is enabled in Windows
If the first step is already set then use step 2 and enter this command at the DOS prompt as the Administrator:
dism.exe /Online /Disable-Feature:Microsoft-Hyper-V
