I recently installed a new hard drive in my computer. It seemed as if I was doing everything well. I followed all of the Steps on the installation CD. Now after the Installation of the hard drive I am unable to enter into the Windows XP OS. It says to press ctrl, alt, Delete to restart. When I restart my computer I can either press Delete to go to the the Bios, CMOS settings or go back to the screen where it says press ctrl, alt delete to restart. What should I do?
