I have a Intel Core i5 64bits laptop with Ubuntu 12.10 as a single boot installed.
I want to install windows 7 64bits in the VM and to do so, I need to enable intel Virtualization Technology in the BIOS.
But after I do that, Ubuntu is still booting, but UI will never start (TTYx consoles work very well).
Any idea where the problem is ? What can I try when UI doesn't start?
