i was receiving an "operating system not found" error message on my Dell Inspiron 1012 notebook. After some research on the internet, I thought I needed to replace my hard drive. I ordered one and thought I was doing the right thing by going from my old one of SATA 250 GB 5400 RPM to a new one of 750GB 5400 RPM. I have successfully installed the new hard drive (I think). I still get the same message. There is no place to put a cd on this notebook. How do I install an operating system on this new hard drive ? I realize I will probably have to pay for it, and thats ok, just want it done . And I'm no techie by any stretch of the imagination' so please be patient with my ignorance. I probably should have just paid someone, but I like to learn/do things myself, so here I am. Thanks
