I was removing my security shield virus manually following some instructions on the net and apparently made some registry changes that only allows the computer to start in safe mode. When I go to the utility to start in normal mode, it switches back to safe mode on boot up. Is there any way to fix the registry without reloading XP? I was not able to make a backup of the registry, it would not let me. Also, I have SP1 disc but was running SP3. Any help would be appreciated.
