I did a board based on Arduino Leonardo with microcontroller 32u4. I want burn the bootloader by ISP, but I can not find the bootloader file.
Do you know where I can find this file?

Thanks a lot!

Well in my windows XP system running IDE 1.0.4 the bootloader file named:

Caterina-Leonardo.hex

is located at:

C:\Documents and Settings\Primary Windows User\My Documents\My Programs\Arduino\arduino-1.0.4\hardware\arduino\bootloaders\caterina

Or just use the bootloader that comes with the part from Atmel?

"- Optional Boot Code Section with Independent Lock Bits
    In-System Programming by On-chip Boot Program
    True Read-While-Write Operation
    All supplied parts are preprogramed with a default USB bootloader"
