I recently had an issue installing Quicktime, so I followed the steps from an online forum that involved changing permissions in my registry. Apparently I changed the wrong setting, as I can no longer log in to XP Home. The computer just stops at the blue XP splash screen, but never goes to the login options. I tried every option I could find online and decided to do a repair/reinstall using the XP boot disc. However, this does not work as the computer just restarts everytime it asks me to verify the language settings. I now have XP Pro running on the computer as well, but I cannot access all files/programs on the XP Home partition of the computer. This is a complicated mess. Does anyone know why XP Home will not reinstall? Are there any other options besides reformatting and starting over? Thanks.
