Hyper Virtualization not working.

[MattNC79]

I tried but could not.  I tried to boot directly from the hard drive but it retured the "no operating system found" error. The Windows Boot Manager is found under the UEFI suppored boot options but not the Legacy.   I have read that that this could be done in the BIOS settings but there is no such menu in my BIOS settings.   Hmmm, wonder if a different BIOS would resolve this problem (scratches his head)    😉

Hi,

Oh,oh.:smileysurprised:  Your PC should not be running in UEFI mode so you must have done a custom installation at some point as it is not normal to see a version 7 BIOS PC run in UEFI mode. This might explain why VT is not working.

OMG. shoot me now!  Yes it was a custom installation of Windows 8.1 Pro.  I didn't go the upgrade route, I did a clean install with Windows 8.1 and converted the drive to GPT.  When Windows installed it created three partitions on the drive, a Microsoft Reserved Partition, an EFI System  Partition and the Operating System Partition.  To be sure , there has to be a way to flip flop back and forth from UEFI and Legacy.  Another question, do the HP BIOS update files have any type of safe guards in them that will tell you if the BIOS you are trying to flash is compatible?  Can BIOS files be customized within the ROM file itself and then repackaged? 

Can I please, please, please,  have a copy of the last BIOS ROM file that AMI provided HP for the Holly motherboard?

Hi Matt,

I flip flop back and forth but I use two different hard drives. One formatted GPT for an UEFI Windows installation and a different hard drive formatted MBR for legacy booting Windows.  If you should try this, then you should be able to use the BIOS boot menu (ESC at power on time) then select Boot options and select the legacy hard drive.

Does the extra hard drive have to be an internal hard drive or can it be an exernal hard drive? I have never had a computer with dual operating systems so this is new to me.

Hi,

I use internal hard drives for booting up a full fledged OS.

I finally was able to get Hyper-V to work, though it was not through conventional methods.  The Hyper-V platform option was still greyed out in add/remove windows functions.  I thought I would share this so that if anyone else had the same issues that I had, they could use the method that I used and see if it works for them.

I opened the command prompt with administrative rights.  At the command prompt I typed the following:

C:\Windows\system32>dism /online /enable-feature /featurename:microsoft-hyper-v-all

The following should appear after you hit enter:

Deployment Image Servicing and Management tool
Version: 6.3.9600.17031

Image Version: 6.3.9600.17031

Enabling feature(s)
[==========================100.0%==========================]
The operation completed successfully.
Restart Windows to complete this operation.
Do you want to restart the computer now? (Y/N)

Hit "y"  and your computer should shut down and configure the new features and start back up.  You can double check to see if all components were installed by going back into the add/remove windows features.  Click on Hyper-V and expand it.  All boxes should be checked.

Everything works as it should.

**Note that is was a work around for my system.  Virtualization technology was enabled in my BIOS but windows did not recognize that it was. This procedure may not work for everyone.***
