I need my laptop for my work every single day. When I saw the message "No operating system found" I frecked out. A friend of mine told me about MJ's Fast Laptop Reapir and I called them. My hard disk was broken and there wasn`t any chance for it to be fixed. MJ's Fast Laptop Reapir replaced it with new one but somehow they managed to extract all the information from the broken one. Thank you so much for this. All my work was on this hard disk. You are the best!
