A few days ago, I could not access my Windows XP because of this error: "Windows XP could not start because the following file is missing or corrupt: \Windows\System32\Config\System". I was still able to access Ubuntu through the Dual boot startup menu. I accessed the Internet using Ubuntu to ask for help.(fourms) I tried all the suggestions for Recovery/Repair using my Windows XP installation disk and it appeared to have fixed my problem, but now it is asking me for my Administrator Password. I used or entered my Admin. Password, yet it won't let me in. When I ask for help, on the Internet, with that, everyone thinks I am trying to break in to someone else's computer and I get no responses or negative responses. It seems that I may have to do a clean Install of my Windows XP. My concern now is if the Dual Boot menu that directs me to either OS, will be wiped out when I do a clean install of Windows XP. BTW, Windows XP is solely on the C Drive and Ubuntu is on the D Drive. Each drive is 80GB. Any final suggestions before I do the clean install? As you can see, I am very hesitant in doing this. One final note, I was able to access some important files from my C Drive through Ubuntu and save them on my Flash Drive. Thanks.
