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. =========================================================================== Patrick DUPRÉ | | email: pdupre@xxxxxxx Laboratoire interdisciplinaire Carnot de Bourgogne 9 Avenue Alain Savary, BP 47870, 21078 DIJON Cedex FRANCE Tel: +33 (0)380395988 =========================================================================== > Sent: Friday, June 21, 2019 at 7:58 PM > From: "Gordon Messmer" <gordon.messmer@xxxxxxxxx> > To: users@xxxxxxxxxxxxxxxxxxxxxxx > Subject: Re: New install > > On 6/21/19 5:35 AM, Patrick Dupre wrote: > > But I get the following message: > > Your bios-based system needs a special partition to boot from a GPT disk label.
