XP is gone and finals coming up

HI Dylan here,

I heard about ubuntu and i thought instantly Wow this is a great os but when i was installing i completely messed up my partitions and now my hard drive is only ubuntu and now it wont even read me xp boot disc.
I have already changed bios to make it so disc goes first but it starts and then disc stops making sound and then ubuntu loads so i dont know what to do i dont know how to use this os even though i think it is awesome i have finals coming up. I Am going to have ubuntu in the future but for now can someone help me please???

WOULD REFORMATTING MY HARD DRIVE FIX THE PROB????

XP IS GONE!!!!!!!!!!!!

Ubunutu booting would have nothing to do with Ubuntu itself - it is your motherboard that determines the boot order. Also, if there is an existing boot loader on a drive already, the XP disc will require you to hit a key during a short timeframe before it will boot into setup.

Make sure your BIOS is set to boot from CDROM before your HDD, and then tap keys as you hear the drive start to spin up.
