Purchased a Dell Vostro Windows XP3 desktop a few months ago. About a month or so ago, I wanted to boot up in safe mode, but couldn't always get there. At least 50% of the time I can't get the safe mode screen to pop up correctly. Instead of the normal safe mode screen, all that shows is Windows Vista on the screen and Windows Vista isn't my OS. I can only hit the enter key and Windows XP load in the normal mode. While needing to go into safe mode is rare, I'd like to fix this issue. Any help is appreciated.
