Had another look at this today, and, as I suspected, it is indeed a firmware limitation of these Dell Precision M6700/M6800 laptops: https://www.google.com/search?q=boot+via+UEFI+32-bit+windows+on+Dell+Precision+M6700 "AI Overview Booting a 32-bit version of Windows in UEFI mode on a Dell Precision M6700 is not typically possible, because the system's UEFI firmware is 64-bit and does not support native 32-bit UEFI booting. Most modern systems, including the M6700, use a 64-bit UEFI, which requires a 64-bit operating system to boot in UEFI mode." -- Fake news kills!
