Update 1 broken Hyper-V


Chancer

Recommended Posts

G'day,

I installed update to my Win 8.1 WMC 64 bit PC yesterday. I have an Asus P8Z77-V Pro motherboard with an i7 cpu.

Windows is activated with a legit key.

Now when I run Hyper-V and attempt to start a VM I get an error saying the Hypervisor is not running.

It worked fine last time I used it !

I have checked in BIOS and virtualisation is turned On. I did turn it off, reboot, turn it on again and reboot just in case. This made no difference.

Has anybody else seen this - or better still can anybody point me in the direction of a solution.

Thanks

G'day,

I installed update 1 to my Win 8.1 WMC 64 bit PC yesterday.

Try upgrading to the 8.1 Update - the one you're running, the 8.1 Update 1 is a beta.

Why do you suggest it is the beta? I would be surprised if it is the beta as I installed it via Microsoft update.

I don't know the antecedents of your installation - but, which one exactly do you have???

8.1 Update or the 8.1 Update 1 which is a beta.

My update history lists Windows 8.1 Update for x64-based systems (KB2919355), along with everything else.

As I mention above I downloaded via Windows update, not from anywhere else.

In that case, I suggest altering the first post from 8.1 Update 1 to just 8.1 Update - when trying to get issues resolved, it's best to submit accurate data. ;)

I have the latest bios.

However the bcdedit /set hypervisorlaunchtype auto followed by a reboot seems to have done the trick.

Thank you very much.

I have also asked Microsoft - let's see if they as quick as you!

My only concern is that it's not the Hyper-V that's really broken - but, rather the BCD that's gone corrupt. B)

Hope your BCD setting survives a shutdown and/or a reboot - fingers crossed. ^_^
