Of course with isolinux or the old grub, the bootloader requires the BIOS to be present to load the first bits from the drive, but once the kernel is loaded and executed, the CPU is switched to protected mode and the BIOS is no longer accessible or used. In BIOS mode it shows an isolinux menu.' Isolinux is a 16-bit real-mode boot loader that has been used to boot Linux on CD-ROMs and DVDs for many years, much like grub (and lilo before it) was used on hard drives.

Linux Mint's install doc says, 'The Linux Mint ISO can be booted both in EFI or BIOS mode. I have confirmed that for DVDs, there is some kind of hybrid boot process. MS does not actually dictate to vendors whether they must provide a way to disable secure boot, so that door is always open (or closed, depending on how you look at it).

According to several articles from a year or so ago (and i haven't seen anything contradicting this), if a manufacturer wants to put a windows sticker on their computer (and they all do since they bundle Windows), MS requires them to enable secure boot by default, and presumably use this to secure the OEM windows install. Interesting to learn this.Д«ut secure boot is definitely still pushed by default and on by default on any computer I've ever seen. Apparently if you are using some legacy drivers, you must disable secure boot.

It appears Windows 10 (at least some variants like Home or Pro) does allow you to boot it with secure boot disabled. My information is a bit dated, back a couple of years when people were trying to dual boot Linux and Windows 10. But not all machines (especially some laptops) even allow disabling secure boot. If you don't need to run windows at all, it's easy to disable secure boot. Also users can add their own keys to the secure boot key store if they make a custom kernel. Linux distros work with secure boot by having MS sign the Linux distro's keys. Secure boot is enabled by default on all shipping systems right now, because Windows requires it. Future versions of Windows will not support legacy boot at all (or BIOS computers), once legacy boot disappears from PCs sometime around 2020.

If using EFI at all, Windows 10 *requires* secure boot be enabled. We can all wish that EFI's secure boot doesn't matter outside of corporate computers, but we'd be mistaken. Nor would it even run without the BIOS resident in memory. I think the DVDs have some kind of dual boot functionality that boots 16-bit grub if you're using legacy boot, or the 32-bit EFI grub if you're using EFI.ДЄs for FreeDOS or MS-DOS, without enabling Legacy Boot, EFI will not boot MS-DOS from an MS-DOS partition.
