I have a computer with an Intel DQ67SW desktop motherboard (released Q1, 
2011).  The Setup utility allows me to select BIOS/MBR mode or UEFI/GPT 
mode.  d-i seems to detect if the computer is running in BIOS/MBR mode 
or in UEFI/GPT mode, and performs an install to match.  So, I installed 
Debian twice (via textual "Install") onto a pair of USB sticks, once in 
each mode.  (An "Expert" installation may offer more options.)


I mostly run my computers in BIOS/MBR mode, and use the BIOS/MBR USB 
stick frequently.


I have limited experience with the UEFI/GPT USB stick.  I need to test 
it on a newer computer with Secure Boot, and may need to create a third 
USB stick.


AIUI d-i and Debian Live are open-source projects.  I believe they both 
support all of the above in a single image.  If you have the skills, 
perhaps you could fork one and create your own image with the tools you 
want.
