I am unable to create a bootable external SSD.
What I did: download fedora 33 and write it to a usb stick:
sudo dd if=Downloads/Fedora-Workstation-Live-x86_64-33-1.2.iso of=/dev/sde bs=8M status=progress oflag=direct
Boot from that stick and start installation to new external SSD. Allow to remove all and everything in that new disk. After some minutes without any error the installation finishes. I reboot after removing the usb stick and the pc did not see any bootable device.
If I simply write the iso image to the external ssd, the ssd boots also in uefi mode ( i believe ).
But I am unable to install a full fedora installation to the external SSD.
Is this a bug? Can I force to use mbr mode if UEFI is a problem ( which is not a problem from usb stick )
Is there any selectable option for selecting the boot mode during installation setup. I did not find anything. I only read somewhere that if I boot not in UEFI from the installation stick, it will install with mbr. But I have no idea how to boot not in uefi from that stick.
I also tried out to create the usb stick with
sudo livecd-iso-to-disk --format --reset-mbr Downloads/Fedora-Workstation-Live-x86_64-33-1.2.iso /dev/sde
But this stick did not boot at all.
Can I check something? No idea to proceed!
