Hello,
I guess that you pointed on one issue.
This machine (a Dell) used to boot efi for fedora, but when I plug the USB
stick I have to boot legacy. It seems that it was the only option to
boot on the USB stick.
While this is what is on the USB:
EFI images isolinux LiveOS
Is someting wrong?
Is it an issue with the stick, or it is because I have not been able to
configure properly the bios to boot on an external USB stick (efi?) ?
Actually, your option #1 is that I prefer.
I can share the efi system partition.
In summary. I really need to boot on the USB stick in efi mode, and
find the way to do it right.
