Macintosh HD name changed to EFI BOOT?? CAMPTUNE

[acuraice]

??? After successfully using camptune to increase the size of my available windows xp SP3 partition via bootcamp on my 24 inch imac,i noticed that when i start my imac holding down the "option key" as usual to select between mac or windows partitions, the name of my "MAC" hardrive, that is almost always named "Macintosh HD" unless changed by the user,which in this case i haven't,has been changed to say "EFI BOOT". why is this? can i change it back? has camptune modified my Mac's Harddrive name forever? thank you inadvance for your help
