In bios it was enabled the legacy option and with bios partition it seems that grub was working in legacy mode ... I set up bios to efi only and deleted the bios partition and from within a chroot (fedora live) i get : [root@x360 /]# efibootmgr -v BootCurrent: 0000 Timeout: 5 seconds BootOrder: 0001,2001,2002,2004 Boot0000* USB CD/DVD ROM Drive (UEFI) ACPI(a0341d0,0)PCI(14,0)USB(3,0)USB(1,0)CD-ROM(1,2b,2798)RC Boot0001* fedora HD(2,c8800,82000,f5495ca8-ccea-4573-afe6-ec42fb4cdb01)File(\EFI\fedora\grubx64.efi) Boot2001* EFI USB Device RC but when i try to boot i receive the message that boot device is not found even if i already did grub2-install /dev/sda from within chroot and also i tried with : --efi-directory=/boot/efi --target=x86_64-efi Any idea how to correct this? Thank you! Adrian
