I've followed Lifehacker's dual-boot instructions. When it boots from the disc, all I get is the Windows 7 desktop with no icons, just 'For testing purposes' at the bottom. I can move the mouse but there is nothing to click on, I have to turn off with the switch.
cntrl+alt+delete to get task manager look in processes see if explorer is running if it is highlight it and click on end task. also if its not .then go to applications and click new task , enter explorer and click ok . I have known this empty desktop to happen with a freind in the past and this cured it ,it did not happen again.
