Having installed the Access Commander virtual machine on your computer; it is possible that the machine may not start and you may encounter an error telling you that VT-x is disabled (or referencing a problem with AMD-V if you have an AMD CPU). This means that the hardware acceleration settings required by the CPU to support virtualization are currently disabled in your BIOS.
Since Access Commander runs in a virtual environment, your computer’s BIOS settings must be configured to allow virtualization. Accessing a computer’s BIOS will differ from manufacturer to manufacturer. Additionally, the same manufacturer may implement different BIOS versions depending on the age or model of your computer.
To access the BIOS, most computers offer a prompt to press a button/button combination to ‘enter setup’ in the first few seconds after turning on your computer. You will need to do this before your operating system begins to load. On some machines, this button/button combination will take you directly to the BIOS settings, on other machines you may encounter a ‘Setup Menu’ which will include an option to enter the BIOS.
If your computer doesn’t offer any options to access its BIOS before your OS loads then it is possible that it uses UEFI instead. Please read further on in this article for information on accessing your computer’s UEFI.
Below is a list of the most common computer manufacturers and information regarding accessing the BIOS settings for each manufacturer.
Most commonly: F2 or Delete.
On older computers: F1 or the key combination CTRL+ALT+ESC.
Most commonly: F2.
Alternatively: Delete or Insert key, and less commonly F10.
Newer models: F2 key whilst Dell logo is on screen.
Alternatively: F1, Delete, F12, or F3.
Older models: CTRL+ALT+ENTER or Delete or Fn+ESC or Fn+F1.
Most commonly: F10 or ESC.
Alternatively: F1, F2, F6, or F11
On HP Tablet PCs: F10 or F12
Most commonly: F1 or F2
Older hardware: the key combination CTRL+ALT+F3 or CTRL+ALT+INS or Fn+F1.
If you have a ThinkPad, consult this Lenovo resource: how to access the BIOS on a ThinkPad.
Sony VAIO: F2 or F3
Alternatively: F1
If your VAIO has an ASSIST key, try to press and hold it while you power on the laptop. This also works if your Sony VAIO came with Windows 8.
NOTE: The location of the Assist button will be different depending on the computer model. Refer to the operating instructions supplied with the computer for the exact location of the Assist button on your model.
Most commonly: F2 key.
Alternatively: F1 and ESC.
Toshiba Equium: F12
As mentioned, the steps required to enable virtualization may differ from the above, depending on the BIOS version of your machine. If this is the case, then you should look for options labeled 'Virtualization Technology' or 'Intel® Virtualization Technology' under the 'CPU Configurations', 'System Configurations', 'Advanced' , 'Security'or 'Processor' tab and check if the option is enabled or disabled. Less commonly, you may find the settings within the 'Chipset' or 'Northbridge' or BIOS specific overclocking tab.
If you have enabled these settings within the BIOS or, having enabled them, you are still seeing error messages from your virtualization software referencing VT-X or AMD-V, then it may be necessary to disable Hyper-V on your computer. This can be done as follows:
On a UEFI-based computer, there is often no button press prompt before the OS loads. Instead, you will access these settings from within the OS. For a Windows system; hold down the Shift key as you click Restart in Windows to reboot straight to that menu. To access the UEFI Firmware Settings, click the Troubleshoot tile, select Advanced Options, and select UEFI Firmware Settings. Click the Restart option afterward and your computer will reboot into its UEFI firmware settings screen.
NOTE: It is also important to note that a 64-bit VM machine will not run on a 32-bit processor. However, you may be able to run a 64-bit VM machine if you have a 64-bit processor but have installed a 32-bit host OS and your processor supports the right extensions. |
