Winload.exe Is Missing Or Corrupt 0xc000000d

I am helping a friend out with her computer, she had one of those annoying viruses that say you have a bunch of things wrong and try to get you to buy stuff and a few others that I can't remember. I ran malaware bytes and got rid of them all. I thought that would be the end of it. She wanted Itunes and it would never install and the error message for it was related to windows updates. She purchased the computer last may and I was looking at the updates and all of the updates have failed since then, first being service pack 1. It wouldn't automatically do it, so I downloaded the standalone file and it would tell me it was unsuccessful and to restart the computer and try again. I downloaded the readiness tool, ran it, didn't work, ran it in aggressive mode, that didn't work. So I gave up and was going to reset it back to factory. The F8 command for the advanced boot methods does have "repair your computer" option but I click it and it just starts windows normally. Over and over. I made a repair disc through the windows options, and dell data safe, and when I boot from them I get the winload.exe file is missing or corrupt status: 0xc000000d and when I use dell data safe program to restore back to factory, it restarts and gives me the same thing. I have googled all day and searched forums for hours and I am getting nowhere. Resetting it to factory was going to be the easy way for me, and now I just want to throw the thing out the window.
