http://ubuntuforums.org – So I made a bootable usb pendrive using universal usb installer. Went and booted my pc from the usb and got to this screen http://i.imgur.com/QdFVi.jpg I hit "install ubuntu on a hard disk" and ubuntu did its thing. After a few seconds It gets stuck here http://i.imgur.com/eN8zu.jpg and that's that it doesn't do anything else. I installed ubuntu on my laptop using the same usb drive and it worked 100%. any help? thanks in advance ):P (Hardware)
