Good day to all, I have some problem with my Dell Inspiron mini 1012. Don't know what to do anymore with this " Operating System not found" error on display screen when I boot up my netbook. I tried all these steps ( Reseat HDD, Load defaults at BIOS, try another working HDD to my netbook, and I tried also inserting my HDD to another laptop but it worked. Only my netbook have some problem.
