Hi. New here, so apologies if this has been asked before. Bought second hand notebook - Samsung NC20, came with no OS installed, but XP installation disc supplied. Bought an external CD drive, and after some playing around managed to install OS. It also came with System Software Media disc for installing, and when I've tried to install this keep getting message saying Windows cannot read from this disk. Have googled the problem, and most people are saying I should remove upper and lower filters in registry. Trouble is, there are no filters in that particular part of registry. Currently unable to do anything else with computer until I install that disc. Anyone know of any fixes?
