Hi, I have a toshiba satellite C650 that has recently come up with a disk read error. I want to access the command prompt to try some potential solutions that I have read about on the internet. I have made a Windows 7 recovery disk using my other acer laptop which also has Windows 7 installed. When I use the recovery disk and it has loaded the files etc it just brings up a black screen and the cursor. Does anyone have any ideas as to why this is happening? I tried booting my acer laptop from the recovery disk and it worked fine. Also does anyone have any suggestions as to why I am getting the 'disk read error - hit ctrl, alt and delete to restart' message? Any help would be much appretiated, thanks.
