Tried to install Windows and am stuck in a loop...

Question

Hello all.
Title pretty much sums up my issue. I have a copy of Windows XP Home Edition that I had used on my dell, and wanted to use it via Boot Camp on my Mac Pro (15' 2009). I began the bootcamp setup, partitioned my hadrdrive, and began the Windows setup. I put the disk in and it said "Setup could not read the CD you inserted, or the CD is not a valid Windows CD." Now the CD is stuck in my drive and every time I reboot, Windows setup stats over.
So, I need help getting this CD out or exiting the Windows Setup.
Thank you for any help.

Five ways to eject a stuck CD or DVD from the optical drive
Ejecting the stuck disc can usually be done in one of the following ways:
1. Restart the computer and after the chime press and hold down the left mouse button until the disc ejects.
2. Press the Eject button on your keyboard.
3. Click on the Eject button in the menubar.
4. Press COMMAND-E.
5. If none of the above work try this:
Open the Terminal application in your Utilities folder. At the prompt enter or paste the following:
/usr/bin/drutil eject
If this fails then try this:
Boot the computer into single-user mode. At the prompt enter the same command as used above. To restart the computer enter "reboot" at the prompt without quotes.
You cannot install Windows using a Dell specific installer disc. You need a retail copy of Windows.
