VT-x features locked or unavailable in MSR error

If you’re trying to install a 64-bit virtual machine on Virtualbox, it’s possible you might get this error. VT-x features locked or unavailable in MSR. (VERR_VMX_MSR_LOCKED_OR_DISABLED). If the system knows you’re installing a 64-bit machine, it will automatically enable ‘Hardware Acceleration’ in the Settings for the virtual installation. If not, you MUST enable it manually.

To fix, restart the computer and go into your BIOS settings. You must enable ‘Intel Virtualization Technology’ or if your computer has an AMD processor, you must enable the settings accordingly.

When you try to reinitialize the installation, you shouldn’t get that error. If you do, please leave a comment below with your error and see if we can’t find a fix.
