My Sony Laptop Model PCG-7153L will not load Windows or anything else. It will not repair through the laptop options either. It has Windows 7. I am not the smartest with computers....PLEASE help me get this fixed. I need info and photos as well as some other things on the computer. I am getting that a disk has failed and to press control alt and delete. I have done this many times and still nothing. Is there a repair disc that I can download to fix this or what do I need to do? Thank you in advance for your help
