That is strange, my BIOS is with the default settings, didn’t enable anything regarding legacy boot in BIOS.
Also, I was using Windows 11, so, it was also with secure boot enabled, TPM and all that…
Edit: Windows was showing in the UEFI along with Enos…

You shouldn’t be pressing F8 during boot process to switch to another OS. When you install Windows in UEFI it creates an efi partition and normally you would use that same efi partition when you install EOS. When EOS installs the bootloader (grub). It is grub that boots both Windows and EOS even if Windows is on another drive. Then you should be booting from the drive that has EOS installed on it because it is grub that boots both. No need to switch drives to boot another OS. Even if you used a separate efi on EOS it is still grub that boots both not the Windows bootloader.
Edit: But of course you need the Windows one for it to boot Windows so if it gets trashed then your pooched as they say!
There is something very wrong here… I’ll create the windows ISO and try to restore from there to see what happens.

Sure things can go wrong and it can overwrite the windows bootloader too. If you use the Windows ISO to recreate the Windows bootloader depending on how you do it you’ll most likely have to come back and run update grub because it’s the one supposed to be controlling the boot. That is if you are using grub!
Had to reinstall the Windows… The boot auto repair did nothing.
It wasn’t so bad because my main system is Enos… Windows is just for gaming…
So just installed, updated a bunch of stuff and it’s good to go now…
