Help Me Windows Xp Setup Freeze

HAY,

MY GATEWAY LAPTOP WON'T INSTALL WINDOWS XP HOME WITHOUT THE CD WHICH I DON'T OWN. IT FREEZES WHEN GETS TO WINDOWS XP SETUP OR THE DRIVE SETUP SCREEN. MY INTERNAL CD ROM IS BROKEN AND WON'T READ ANYTHING SO I GET AN EXTERNAL DVD/CD WRITEABLE DRIVE I CANNOT INSTALL IT WITH THE DISK BUT IT WORKS. WHAT DO I DO TO GET MY COMPUTER TO INSTALL WINDOWS ALL THE WAY

THANKS
