Can't install Hyper-V on Windows 8.1 Pro

I have a Dell XPS L702x laptop with 2 hard drives, one of them has a MBR partition and has Hyper-V running without problems, but in the second drive, which is a SSD disk and has a GPT partition, I can't install it. It seems to install, gets to about 95% and then I get a message: "Failure configuring windows features, reverting changes" and then it reboots and reverts the installation attempt.

I have tried the following commands:

DISM.exe /Online /Cleanup-Image /ScanHealth
DISM.exe /Online /Cleanup-Image /RestoreHealth
Sfc /scannow

But no errors were found, and I also run coreinfo with this results:

Can you clarify what you're trying to do as it's unclear to me? You've got a laptop with two drives, and you've already got Hyper-V installed on the laptop, and you're now trying to install it on the other drive?

If that's the case then I'm unsure why you think you need to.

You only have Hyper-V installed once on a machine, and it's ALWAYS installed on the boot partition of the machine because that's how it works. Effectively once installed the Hypervisor sits on the boot partition, and the local copy of Windows becomes a management VM running on top of the hypervisor (that's why the VM's you create get as good performance as the host OS does, as they sit alongside each other rather than on top of one another).

If you're trying to use the second drive (the SSD) for Hyper-V then you simply need to create a new VM from within Hyper-V that you have installed already, and during the installation you're able to choose where to put the VM files, at which point you can set it to use the SSD for those files.

I've got the same setup on my home machine, though in reverse, eg my boot partition is an SSD, and I've got a large HDD that hosts my VMs.

Hello, I have Windows 8.1 Pro installed on both drives, and now I'm trying to install from scratch all the tools I have in the HDD into the SSD, but I can't install Hyper-V on the SSD, which is my primary boot drive now.

Hi Juan

"It seems to install, gets to about 95% "
Do you enable the feature with the "dism.exe /Online /Enable-Feature:Microsoft-Hyper-V /All " command line ?

If so ,we can check the dism log for more information to troubleshoot this issue .
Here is the log location :
C:\Windows\Logs\DISM
If you have trouble in analyzing the issue ,please upload them to the OneDrive and paste the link here .

Best regards

Hi, yes, I tried to install with both methods, from command line and through "control panel->Turn on or off windows features" with the same result.

I have been checking my dism.log file and I can see some chinese characters, but my windows 8.1 is in spanish. What could it be?


This is my dism.log

Yes, of course, I can run VirtualBox or the android emulator with the intel HAMX driver without problems.

Hi Juan,

Have you tried to open the other logs to have a check ?

We can try to change the format of the log or re-save the log and choose the encode type to have a check .
If it is possible ,we can download a software to read the .log format files .

To verify whether it is caused by the log itself ,we can try to open it in another machine or upload the whole .log file to the OneDrive if it is possible .

Best regards

Hi, the other logs are ok, all of them are written in english. I have verified that this behavior comes after upgrading my Windows 8 Pro to Windows 8.1 Pro through the market App.

My dism.log is uploaded here:

Hi Juan Fco,

"gets to about 95% and then I get a message: "Failure configuring windows features, reverting changes""

What is the exact error code ?

From the log you uploaded ,I noticed that the last known good log format is related to the winRE. Have you made any modifications to this system or tried to repair the machine in winre environment ?

Apart from this ,please check the Event Viewer for related errors to troubleshoot this issue .

Best regards

Hello, I don't know what's the error code and I haven't made any modifications related to winRE, but it seem's I have found the problem.

I think the problem was due to kasperky internet security, because I installed all the system from scratch again and I installed Hyper-V before KIS and it worked.

The chinese characters still persist on my dism.log, but finally, I have Hyper-V working.

Thanks for your help.

Glad to hear you got it working! Annoyingly now you mention AV I remember having issues with AVG with my Hyper-V install (but completely forgot about), though can't remember if it was installation stage or when installing VMs.

For info assuming you're planning to install AV on there again, this http://blogs.msdn.com/b/virtual_pc_guy/archive/2009/03/17/antivirus-and-hyper-v-or-why-can-t-i-start-my-virtual-machine.aspx details which files/folders you should exclude from being scanned to ensure it doesn't cause issues with your installation.
