I *think* it's not that, it's the removable-medium boot sector that's
the problem. Linux tools know how to write a Linux-compatible boot
sector but it's not compatible with modern, both-BIOS-and-UEFI-capable
Windows.

Back in the XP era, UEFI & GPT (and even SATA) were not yet issues,
everything was MBR & BIOS only, but of course MS didn't make official
ISO images available back then.

(IIRC WinXP only supported SATA and USB 2 after Service Pack 2.)

Unfortunately the advent of GPT disks, while simplifying partitioning,
has made booting considerably more complex, and while I cannot prove
that Microsoft *intentionally* set out to make life more difficult for
FOSS software creators, my very strong suspicion is that Microsoft would
be very happy with anything that inconvenienced them. Enterprise vendors
who can pay for signed bootloaders have less problem with this.

Apple adopted UEFI earlier, even on its early x86 kit which was 32-bit
only, but then Apple does not really care about booting anything else.
Apple kit is solely designed to run macOS and (later) to dual-boot macOS
and Windows. Non-macOS Unix people are on their own.

    This sounds plausable to me because when I used a windows system to write it

    the first thing it did was write a partition for uefi,,,,,,,
