I have a Dell computer that runs Windows XP. Last week, I tried to disable autorun by editing registry. But I am not experienced in registry editing. When I started up the computer, it failed to boot. Then I tried to repair it using recovery console, unfortunately it says your password is wrong and I couldn't log in. Then I tried to repair it using Windows XP CD. After installing for a while, it asks me to give a file called iamudlg.exe. I gave it that file but couldn't proceed to finish the installation. Now I have installed another XP os on D:\ (the previous one is on C:\). But I couldn't access the files on C:\Documents and settings\admin\ because of administrative password. What do you advice me? Can I finish the recovery installation? Or is there a way I can access those folders from the second OS? Thanks!
