Thought I was immune from all this when I prepared my boot usb! LOST IT!! Like many before I have screwed my netbook which now happily tells me " Missing operating system" and freezing. I've tried various option - creating w98 boot usb etc but no joy. Before I invest in Techg@@s 35 quid disc, has anyone had a similar message and been able to download said disc onto usb,then successfully start the machine? Or got the time to pm me the download? Many thanks.
