<p>I had created a Virtual switch with the name "Minikube2" . Previously I had created  Virtual switch with the name "minikube" ,but deleted it later as there was config issue. </p>

<p>Did all the required configuration -"sharing on ethernet .." </p>

<p>Now when I try to run  </p>

<p>minikube start --kubernetes-version="v1.10.3" --vm-driver="hyperv" --hyperv-virtual-switch="minikube2"</p>

<p>it downloads the ISO , but fails to configure the switch -</p>

<p>it says vswitch "minikube2" not found</p>

<p>Short answer is to delete <code>C:\Users\%USERNAME%\.minikube</code> and try again.
Below is my investigation:</p>

<p>First I have created Virtual Switch "minikube", started the cluster and it worked as expected. 
Then I stopped minikube, created new "Minikube2" switch and started minikube</p>

<pre><code>minikube start --kubernetes-version="v1.10.3" --vm-driver="hyperv" --hyperv-virtual-switch="minikube2" --v=9
</code></pre>

<p>Appeared issue:</p>

<p>Then I deleted <code>C:\Users\%USERNAME%\.minikube</code> , minikube vm inside Hyper-V and started again:</p>

<pre><code>C:\Windows\system32&gt; minikube start --kubernetes-version="v1.10.3" --vm-driver="hyperv" --hyperv-virtual-switch="minikube2" --v=9
</code></pre>
