I NEED TO UPDATE MY BIOS ON  ACER ASPIRE E1 431.BEACUSE I NEED TO ACTIVATE VIRTUALIZATION.

IronFly

 How can i understand which version i need to download?

Laptop versions:

1.xx can only be updated using 1.xx versions

2.xx can only be updated using 2.xx versions (normally 2.xx version are labeled "not for upgrades")

 

Desktop versions:

P01.xx can only be updated using P01.xx versions

P11.xx can only be updated using P11.xx versions (normally P11.xx version are labeled "*not for upgrades")

"L" BIOS versions are Linux OS dedicated (example P01.xxL)

 

* what does it mean "not for upgrades"?

During the windows 7 to 8 transition, some PC models had different BIOS versions from factory, related to the installed OS.

Windows 8 PC got an UEFI BIOS

Windows 7 PC got a "Legacy" BIOS

So PC with Windows 7 installed from factory can't use the "not for upgrades" BIOS version, even if they were upgraded to Windows 8 or 10, since the factory BIOS was a different version compared to PC with Windows 8 from factory.

------------------------------

Most of recent Acer laptop models support both Hyper-V and VT-x* (not AMD CPU models), they are both enabled even if those options are hidden on BIOS.

If your laptop has an Intel CPU, you can check if you CPU/system supports virtualization instructions, using Intel Processor Identification Utility:

If your laptop has an AMD CPU, AMD-V is disabled by default on BIOS and can't be enabled.

Devices using Windows 10 Home will need to upgrade home to Windows 10 Professional or Enterprise to use Hyper-V. Windows 10 requirements can be found here:

* If Hyper-V is ON, VT-x will not be available; Hyper-V must be OFF to have VT-x recognised by virtual machines.

Turn OFF Hyper-V

Open a Command prompt with administrative rights (Admin)

type

bcdedit /set hypervisorlaunchtype off

exit

Reboot your OS

or

Go to Control Panel -> Programs -> Programs and Features -> click Turn Windows features on or off -> un-check Hyper-V -> click OK

Turn ON Hyper-V

Open a Command prompt with administrative rights (Admin)

type

bcdedit /set hypervisorlaunchtype auto

exit

Reboot your OS

or

Go to Control Panel -> Programs -> Programs and Features -> click Turn Windows features on or off -> check Hyper-V -> click OK
