When I execute
Code:
efibootmgr --create --gpt --disk /dev/nvme0n1 --part 2 --write-signature --label "Gentoo" --loader '\EFI\Boot\bootx64.efi'

efibootmanager create entry, but with non signature and strange parameter of hard disk

When I reboot , system boot from "UEFI OS" and entry "Gentoo" has only "VenHw(0000000000000000000)", intead entry "UEFI OS" seems to have correct values (again "file")

I don't understand what it's wrong.

Can someone help me?

guerro ... can you provide the output of the following:

Code:
# gdisk -l /dev/nvme0n1
# efibootmgr -v

... also, with your command if you add '-v' you should get more verbose messages.

best ... khay

guerro ...

I have no idea about what sort of efi executable this "UEFI OS" is, but it seems to be altering the boot entry, you could switch the BootOrder, delete that entry, or install something like rEFInd in its place (after backing up {ESP}\EFI\BOOT\BOOTX64.EFI). Actually, I wonder why you need two ESP's (EFI System Partition), you should be to make an entry pointing the HD rather than the PCIe SSD.

So, rather than I recommend you perhaps break something, I suggest you search for this particular efi executable, and see if there is some reason why you need it. I'd probably just remove it and use some other executable in its place ... but that may be hasty (as, again, I'm not sure what it is or what it does).
