VT-x is not available, but is enabled in BIOS

Il y a three common culprits for the type of error the user is seeing:

  • VT-x is not enabled in the BIOS

  • The CPU doesn’t support VT-x

  • Hyper-V virtualization is enabled in Windows

Since the user already eliminated the first two possible culprits, the next step is to open a invite de commandes en tant qu’administrateur and run the following command:

dism.exe /Online /Disable-Feature:Microsoft-Hyper-V

Afterwards, reboot the PC and try VirtualBox again.
