Drivers disk

Hi, motherboard went bad in my computer and i replaced it with new board , when i put the drivers disk in it keeps booting into windows and i tried setting the 1 boot drive as cd and tried disabling everything except boot from cd and still keeps booting into windows, cables are correct jumpers are correct but when i let it go into windows it wont let me log on it wants me to authenticate it, its the same harddrive and never had to do that.
