Hello Igor, I did not have to use your recommendations. But you say grub2-install --boot-directory=/boot /dev/sda 1) I though it was not recommended for a efi boot. 2) is it always in /dev/sda (if the /boot/efi is on sdb)? =========================================================================== 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: Tuesday, June 25, 2019 at 9:09 PM > From: "Igor Bezrodnik" <ledeni@xxxxxxxxxxxxxxxxx> > To: users@xxxxxxxxxxxxxxxxxxxxxxx > Subject: Re: Booting impossible > > Patrick, you need this steps to boot your system : > > Using the GRUB2 boot prompt > > If improperly configured, GRUB2 may fail to load and subsequently drop > to a boot prompt.
