How to enable the hardware virtualization of a HP Probook 4431S laptop in BIOS properly?

Super User Asked by AnjanaDyna on October 13, 2020

I have an HP Probook 4431s laptop. Installed Windows 10 Pro on it.

Device specification is:

Manufacturer/Model : HP ProBook 4431s Notebook PC (ENERGY STAR)

System type: X64 based PC

Processor : Intel(R) Core(TM) i7-2620M [email protected] 2.70GHz, 2701 MHz, 2
cores, 4 Logical processors

Disk: SSD ( 223.57 GB )

RAM: 16 GB

BIOS mode: Legacy ( BIOS )

OS: Windows 10 Pro (2004 edition)

I want to install Docker for which i have to first enable the hardware virtualization via BIOS.

Entered in BIOS by pressing F10 on startup -> Go to System setup tab -> device configurations -> enabled options Virtualization technology and Virtualization technology for directed IO -> save -> exit

After that i booted into windows 10.
When i checked the performance tab of task manager, it shows that

Virtualization : Disabled.

This causes the docker start failure with error:

Hardware assisted virtualization and data execution protection must be
enabled in the BIOS

I tried to modify the security settings of virtualization from ‘view’ to ‘change’ in BIOS.
But it didn’t helped.

Now after trying enabling and disabling these BIOS options, laptop takes alot of tme to boot and sometimes windows fails to respond.

How can i fix this?
