Virtual box VM will not be started if Virtualization Technology (VT-x) is not enabled in BIOS.
It will throw below error while starting the VM
Reason for the Error
The host system must support hardware virtualization. Your host system must have 64-bit CPUs that support Intel™ Virtualization Technology (Intel VT, first released in 2005) or AMD Virtualization (AMD-V™) Technology (first released in 2006) hardware-virtualization features.
Most new CPUs from Intel and AMD contain the required virtualization extensions. These virtualization extensions are not normally enabled by default in a new machine. It is necessary to enter BIOS in your system and enable virtualization extensions before attempting to run any virtual machines.
Solution
Please follow the below steps to enable
- Power ON the System.
- Enter the BIOS setup by pressing ‘F2’ or ‘Del’ or ‘Enter’ key (The key may vary depending on your System Model, please follow the on screen instruction during Power ON).
- Look for an option labeled by ‘Virtualization Technology’ or ‘Intel® Virtualization Technology’ under ‘CPU Configurations’, ‘System Configurations’, ‘Advanced’ or ‘Security’ tab and check if the option is enabled or disabled.
- If the option is disabled, enable the same.
- Save the BIOS settings and Boot into Windows by pressing ‘F10’ key (The key may vary depending on your System Model).
