Windows 10: Windows 10 computer failed hard after changing VT-x and Intel Virtualization Technology for...

For reference, my system is:

i7-4790k

ASUS ROG Maximus VII Formula

32GB RAM

ASUS ROG GTX 980


So I installed Oracle VM with the intent of installing Linux on a Virtual Machine to learn. To install the 64-bit version of Linux though, I had to make a few changes to my system. I disabled Hyper-V in Windows Features, and in my BIOS I enabled Intel (R) Virtualization Technology and VT-x. After doing all this, everything seemed to be working fine, except that my computer started acting up. When waking from sleep or powering on, it would sometimes get stuck on the POST screen, and pressing F2 or Del would do nothing. Pressing the power button once, then again, would start the wake sequence again and usually fix it. This lasted for about a week or two, and then it changed. I tried to wake it from sleep, and it froze on the POST screen again. My usual fix didn't work either, I tried multiple times, but couldn't get into BIOS. Q-code was A2 (IDE detected). It was obvious that this was due to the changes that I made in BIOS (though I have no idea why), so I decided to reset the BIOS. I unplugged and held the power button for 30 seconds. I tried to reboot again, still didn't work. So I figured that from the Q-code, it was having trouble finding the boot drive for some reason. So I unplugged the SATA from my boot drive and tried again. This time, a red window popped up saying:


SECURE BOOT VIOLATION

The system found unauthorized changes on the firmware, operating system, or UEFI drivers.

Press [OK] to run the next boot device, or enter directly to the BIOS setup if there are no other boot devices installed.

Go to BIOS Setup > Advanced > Boot and change the current boot device into other secured boot devices.


I had to press enter twice to get past this, I presume because it tried and failed to boot from my other two drives. Then I was able to get into BIOS, and reset to defaults, so I shut down, plugged my boot drive in again, got back into BIOS, and reset my boot drive to boot priority 1. That let me finally get back into my computer, but by resetting my BIOS, I've lost the ability to run Linux on my VM.


What happened? Where did I go wrong? Why was my startup troublesome, but still functional for a while, and why did it suddenly decide to hard stop? How do I try again so I can run my VM without having to go through this process again?

Intel VT-x Enable?


I am unable to find anything with Intel Virtual Technology anywhere in the BIOS. I guess the only step is to update my BIOS, but I heard that is very risky. Is there any other way to enable Intel VT-x?

I have access to my graphics settings but I don't know if that will help.

 

Cannot find the option to enable intel vt-x in Windows 10

Watch this youtube video:

Turn on Intel Virtualization Technology (vt-x) in Windows 10 & 8.1 from BIOS

 

vt-x - virtualization technology

Assuming your hp probook 4530 is the standard specs for your model then you have an intel Core i5-2410m.

Intel lists this chip as having VT-X, one of the prerequisites for hyper-V.
Microsoft provides a page for hyper-v support.

The summary is:

• 64 bit processor with Second level address translation
  
• VT-C for intel
  
• 4GB ram
  
• BIOS Enable Virtualization technology & Hardware enforced data execution prevention.
  
• Windows Professional or higher
  

You can check if your system is hyper-v ready by running cmd prompt and typing systeminfo.exe. At the bottom there will be a Hyper-V section and it will inform you if you have all the settings enabled.
