Just installing Fedora Silverblue and realised that if you boot into the USB disk in legacy mode, it does a legacy install. If you boot into it in UEFI, it does a UEFI install.
Wish this was made clear in the interface and you could actually choose what you wanted. I mean, I really think UEFI should be the default no matter what these days with the option to change it if you really want to, no?
@aral it's not really possible to do a UEFI native install when booted in CSM mode - it's literally not possible for the installer to write a UEFI bootloader entry, the firmware does not expose the necessary interfaces.
we could make it possible to do a BIOS native install from a UEFI boot, I guess, but it seems like a weird thing to do.
@adamw Ah, didn’t realise it was a firmware limitation. Makes sense, then.
