My toshiba laptop won't boot up. i have tried the various options on boot up but none of them work and even though it attempts to try and repair the system after a few seconds the screen goes blank. I have spoken to Toshiba and they said that I need to use a recovery disc but I can't find it. They told me I could buy one but it would cost me £30! Are there any websites where I can download the necessary files onto a PC and then copy them onto a disc for installation onto my laptop?
