How to remove boot options window

Hi All, When Windows 7 beta came out, I installed it on a separate
partition using a free for 30 days program to create the partition. Now
I've formatted that partition to remove Windows 7 and wonder if there is a
way to remove the boot option window that still comes up when I turn the XP
machine on. I tried inserting the XP OS cd to possibly repair this but this
CD is not bootable I guess. I have CD set to boot first but it just
bypasses and goes right to the boot option window anyway. Or is there a way
to initiate a reinstall/repair using this non-bootable CD?

Or does XP have a tool I could use to eliminate this boot window? I played
with the Windows 7 for a while but now I'd like my XP back fulltime.

Thanks very much for any ideas!! Katy
