UEFI (Unified_Extensible_Firmware_Interface)

UEFI is a sticky topic to address but is quite simple to jamesbond. a developer of FAT DOG, see uefi-harddrive instructions.

Light house Puppy, basically a User Friendly or "noob oriented" re-spin of FAT DOG may have a way to install it with UEFI too!

UEFI is the term for the new BIOS interface specification, and is not to be confused with secure boot, which is a "module" or "add - on" that was forced on the main board manufactures. It can be disabled, by going to the "advanced" tab of the BIOS, and doing two things, enable CSM and Legacy Op Rom.

If you want to run any version of you MAY have to use Secure Boot. No puppy variant has solved the issue of getting signed keys from Microsoft, in order for it bypass secure boot but this only applies to "CLASS 3" UEFI systems and is usually from "pre-built" or other wise "mass - produced" computer vendors. Otherwise, simply go into the UEFI BIOS and modifying settings as stated, should work, unless it's of the class 3 specification.

How can you tell the difference between class 1,2 and 3?

while the last link is for a laptop, it should still at least give a pointer as I believe that the UEFI BIOS specifications are nearly the same.

Basically if you go into advanced settings and do not see any "Firmware options" (CSM, Op-rom, etc) in that Tab, then you got a "Class 3" UEFI BIOS Implementation.
