Thanks a lot for the tip! I am also planning to start with a 32GB USB
3.0 stick. It looks like though that you are having EFI and BIOS mode
both supported. Would you share how did you achieve it?
I usually pre-format SSD's, sticks with a "standard" partition layout using
gdisk before installing Fedora.
This was it for this stick - "BIOS" & "EFI" boot partitions.
All my machines have compatibility mode for booting.
F27 was installed on this stick on a machine with EFI but
"BIOS" mode was selected/forced during installation.
I have just re-tested the stick
It will boot on a 10 year old
laptop with dual AMD Althon & only USB2.
Also on Intel i7-6700K machine using "BIOS" mode.
