Trying to install Fedora 14 on a Stubborn Sony Vaio

[Jim]

A Sony Vaio will not let me boot on cdrom with a Crashed Windows OS, 
trying  to install Fedora only on laptop. Even if I have BIOS set to 
boot off Cdrom.

I even hooked a external cdrom to usb and enabled in Bios to be first 
boot device, won't work,  in all cases it  will only Attempt to Load 
Windows.

It won't even let you disable hard drive in Boot process.
