Good afternoon,
I don't understand how to determine whether the BBB is booting off the SD 
card or booting off the internal flash. 
Here's what happened, I installed a 4GB image from getting started section 
onto my SD card
This was the first image here:
http://beagleboard.org/latest-images


Initially I powered on by holding the button next to SD card, It booted and 
I could tell it was not the internal image, because it did not have the 
demo applications.

Next, I tried hitting the reset button to see if it will boot off the SD 
card again, nothing happened and I could not connect to the BBB any more. I 
scanned all ports and it was not available.

I tried resetting and holding down the button again, but it would not boot 
off the SD card.

Only when I take out the SD card the BBB boots into the original 
installation.

Does anyone know what may have caused this? This is a brand new SD card, 
and I doubt I had damaged it by resetting the BBB.

As far as I understand there are 3 booting options, 

   1. There is booting off internal NAND which only has 70mb (or is this 
   only a partition
   2. Booting off SD card
   3. "If using BeagleBone Black and the image is meant to program your 
   on-board eMMC, you'll need to wait while the programming occurs. When the 
   flashing is complete, all 4 USRx LEDs will be lit solid. *This can take 
   up to 45 minutes."*
   

What I don't understand is how to select how the device boots. How can I 
make it boot off the SD card every time? How do I prevent it from writing 
to the NAND? I want to prevent damaging anything by overwriting the NAND 
and only work within an SD Card.

Wouldn't it have been easier to install a jumper to select which memory the 
device boots from?

Thanks,
