Source of a complete image for the BBB?

hi,

A colleque bought a new Beaglebone black, flashed a SDcard
with an image, which was said to be a "complete image".

But that was only the Debian Rootfs.

What is a good source for an image which comes with
uEnv.txt/UBoot/kernel and rootfs?

Thank you very much in advacne for any link!
Best regards,
Meino
