I'm with
@KGIII here.
Yes, Linux happily supports UEFI, but 90% of Linux users don't tend to bother with dual-booting, so the need to keep Windows happy doesn't exist.....and anyone with any sense will keep Windows & Linux on completely separate machines anyway. You learn this through experience; it's a great idea in theory, but in practice after the first couple of Windows updates you'll be screaming at the 'puter & tearing your hear out!
When I got this current HP Pavilion tower a little over 3 years ago, the very first thing I did was to go into the BIOS, disable the FastBoot/SecureBoot crap, and set it to legacy booting. I then booted into a Live Puppy CD and immediately nuked the pre-installed Windows 10 with
extreme prejudice.....this was intended to be a Linux-only machine right from the outset, and Windows was NOT getting its smelly claws anywhere near my nice new hardware!
Over the next few days, the 'kennels' then got set up exactly the way I wanted it... It's changed very little since.
-------------------------------------------------------------
Ever since the 700-series FatDogs, when
jamesbond &
kirk shared the relevant mechanism & software 'key' with the main Puppy community, newer Puppies have all had the ability to install/boot in UEFI mode if required....at least in theory. ISOs are released in "isohybrid" format, meaning they'll install/boot either way. UEFI boot for Puppies CAN be achieved, but in practice because the method for doing this is so convoluted (mainly due to Puppy's construction), most folks just go with Legacy boot and leave it at that.
Which is fine.....until manufacturers begin to remove user options from their UEFI firmware, making it impossible to boot anything other than officially 'signed' Linux distros, and locking hardware into UEFI-only operation.
Give it time. It's going to happen, SOONER or later.
