Tried to fix a harddrive on my system which is running WinXP service pack 2. When it was about to install the OS the cdrom drive opened. Now when i reboot i have a choice of OS to boot. One is Win XP and the other is Win XP setup. How can i get rid of the 2nd choice? It also only give me 3 secs to decide. I get an error when i do let it go through the setup. It will not let me cancel the setup and has me reboot. I need help!
