I installed XEN using these instructions
Now when I rebooted virtualbox doesnt work, X doesnt work, lightdm doesnt work
How can I set it back to how it was before? I presume I want to revert the following actions:
Modify GRUB to default to booting Xen:
sudo sed -i 's/GRUB_DEFAULT=.*\+/GRUB_DEFAULT="Xen 4.1-amd64"/' /etc/default/grub sudo update-grub
Can someone tell me how?
