Following up on Windows 10 not being detected I have a strange (to me) issue...

Windows 10 created an EFI partition

Fedora did a EFI install but DID NOT install the EFI data to the EFI partition that Windows created and DID NOT create one of its own. The Fedora EFI files are installed to the plain /boot partition.

Now I will say this is a somewhat older computer and has pretty early EFI support (EFI Ready). There's no configurable EFI options in the BIOS other than for CD/DVD booting.

Thoughts?

I believe this means that Fedora did not recognize your machine as using UEFI
and is using classic BIOS boot instead. When you installed Fedora and
booted from a CD or USB stick, you likely got the option to either boot
Fedora in classic BIOS mode (probably marked in your BIOS boot menu as just "USB storage"
or some such) and to boot it in UEFI mode (marked with EFI in the name somewhere),
I think you probably picked the classic option, causing Fedora to do
a classic install.

Since you are getting what is most likely a classic BIOS grub version now
when booting now your BIOS likely remembered that you booted in classic mode
the last time and stuck with that.

If Windows 10 expects to be loaded through UEFI then chainloading won't work.
Take a look in your BIOS if you can turn EFI mode on, or try hitting F12 / F8
(or some such) to get your BIOS boot menu. Probably you can choose between
UEFI and classic booting your harddisk.

If you've not customized Fedora a lot yet, it is probably best to
re-install Fedora and make sure you pick the UEFI boot option this time.

Regards,

Hans
