http://askubuntu.com – I've bought myself a new pc which comes with a Windows 8 preinstalled and I want to install a linux distribution onto it, ubuntu 12.04 LTS would be just fine. I've tried booting it from a USB (linux pendrive) but it seems the computer won't detect it. It's a packard bell easynote te laptop. I've also tried to install it with a virtual machine but the vm screen went black. Could someone help me out, please. I don't have the levels of linux knowledge that many of you possess so please bear with me if you can. Thank you. (HowTos)
