grub does not properly set efi boot on NVMe device

grub does not properly set efi boot on NVMe device

[Benoit Gschwind]

Hello,

I found an issue when I use:

grub-install --boot-directory=/boot/efi/EFI/gentoo --efi-directory=/boot/efi

Note that the EFI partition is mounted at /boot/efi and I use grub 2.02beta3

After grub-install, I get the following boot setup:

localhost ~ # efibootmgr -v
BootCurrent: 0000
Timeout: 0 seconds
BootOrder: 0001,0000,0004
Boot0000* ubuntu
HD(1,GPT,[hidden],0x800,0xfa000)/File(\EFI\ubuntu\shimx64.efi)
Boot0001* gentoo
HD(1,0,00000000000000000000000000000000,0x0,0x0)/File(\EFI\gentoo\grubx64.efi)
Boot0004  Windows Boot Manager
HD(1,GPT,[hidden],0x800,0xfa000)/File(\EFI\Microsoft\Boot\bootmgfw.efi)
[hidden]
Boot0006* M.2 PCIe SSD  BBS(HD,PM951 NVMe SAMSUNG 512GB ,0x0)..BO
Boot0008* UEFI: PM951 NVMe SAMSUNG 512GB, Partition 1
HD(1,GPT,[hiddent],0x800,0xfa000)/File(EFI\boot\bootx64.efi)[hidden]

When I reboot my computer skip the entry 0001 and load the entry 0000,
and also remote the entry 0001 from the boot order.

If I setup the boot loader with the bios, I get the following _working_
setup :

localhost ~ # efibootmgr -v
BootCurrent: 0002
Timeout: 0 seconds
BootOrder: 0002,0004,0000
Boot0000* ubuntu
HD(1,GPT,[hidden],0x800,0xfa000)/File(\EFI\ubuntu\shimx64.efi)
Boot0001* gentoo
HD(1,0,00000000000000000000000000000000,0x0,0x0)/File(\EFI\gentoo\grubx64.efi)
Boot0002* gentoo
PciRoot(0x0)/Pci(0x1d,0x0)/Pci(0x0,0x0)/NVMe(0x1,[hidden])/HD(1,GPT,[hidden],0x800,0xfa000)/File(\EFI\gentoo\grubx64.efi)
Boot0004  Windows Boot Manager
HD(1,GPT,[hidden],0x800,0xfa000)/File(\EFI\Microsoft\Boot\bootmgfw.efi)[hidden]
Boot0006* M.2 PCIe SSD  BBS(HD,PM951 NVMe SAMSUNG 512GB ,0x0)[hidden]
Boot0008* UEFI: PM951 NVMe SAMSUNG 512GB, Partition 1
HD(1,GPT,[hidden],0x800,0xfa000)/File(EFI\boot\bootx64.efi)[hidden]

The entry 0002 is properly selected, and work fine. Note also that I can
remove the entry 0001 without trouble.

I hope that may help to improve grub.

Best regards

EFI menu entries are created by efibootmgr. Please run grub-install with
option --debug and make full log avaiable.
