title: How do I remove Xen from Ubuntu?
body: <p>I was trying to install VM software on my Ubuntu system. Since I'm not very familiar with linux I followed <a href="https://help.ubuntu.com/community/Xen" rel="nofollow noreferrer"><strong>a guide</strong></a> on the official Ubuntu site. Now I am running Ubuntu in a Xen environment, but I don't want to use Xen to make my virtual machines.</p>
  <p>I installed Virtualbox in order to create my VM's, but Virtualbox doesn't run in a Xen environment.</p>
  <p>I have tried googling for a way to remove Xen from my system, but I am unable to do it. This is what I've tried so far:</p>
  <ul>
  <li>Editing <code>/boot/grub/grub.cfg</code> <code>set default=&quot;Xen 4.1-amd64&quot;</code> to set <code>default=1</code> which was recommended by a tutorial. It made my laptop start up in recovery mode and I had to generate a new grub config file which put the default back to xen.</li>
  <li>Editing <code>/boot/grub/menu.lst</code> but I don't have any files called that on my system</li>
  </ul>
  <blockquote>
  <p>user@BEL-8WF4XW1:~$ sudo find / -name menu.lst</p>
  <p>user@BEL-8WF4XW1:~$</p>
  </blockquote>
  <ul>
  <li>Looking through software center, but I couldn't find anything about Xen</li>
  <li>The command <code>make uninstall</code> but I didn't use the source code.</li>
  <li>I also tried to install <code>yum</code> and do <code>sudo yum install kernel</code> followed by <code>sudo yum remove xen kernel-xen libvirt</code> but that also didn't work.</li>
  </ul>
  <p>I'm quite lost to be honest. Can anyone help me to get my Ubuntu back to how it was before I tried to follow that guide?</p>
