Which is what lead me to this conclusion. Grub-install -target=x86_64-efi -efi-directory=/bootĮFI variables are not supported on this system. Secure Boot state is Enabled (and greyed out)Īs part of the handbook install, when running There is also a lot of confusing information on what the target systems BIOS should be set to, If it is not, how can I recreate it (from another Gentoo system) as UEFI? (and check it is UEFI once booted, before I chroot) Read a lot of posts here about UEFI and it seems the consensus is to boot from a UEFI disk first, but the handbook refers to the minimum ISO supporting UEFI since Aug 2018.Ĭan I check the USB key that was created with Rufus in Windows 10 is truly working as UEFI?

Thought I had followed all the handbook install steps for UEFI, but system will not boot ('no system disk' message). Posted: Wed 11:55 pm Post subject: How to install for UEFI from USB key? Gentoo Forums Forum Index Installing Gentoo

…or, most likely, I've misunderstood something.Gentoo Forums :: View topic - How to install for UEFI from USB key?.The copied Ubuntu shim is somehow expecting different keys from what mokutil is looking at?.The copied Ubuntu shim is trying to boot something other than the grub圆4.efi next to it?.I'm somehow booting some other shim somewhere?.

When booting local GRUB: Boot0001 -> copy of Ubuntu shim -> rejects my GRUB but I don't know why.Here's what I did: # cat >grub-initial.cfg Ubuntu shim -> Ubuntu GRUB -> Linux or Windows does not have the '1.3.6.1.16.1.2' ID like the distro-generated ones which would restrict it to kernel-module signing. There are subsequent 'Shim UEFI key management' dialogs through which I can enroll the hash of grub圆4.efi but weirdly having done that I still get the same result on the next boot, and the presented hash did not match a direct sha256sum of grub圆4.efi or any other file in /boot/efi. Verification failed: (0x1A) Security Violation So I thought enrolling a MOK and signing a standalone version of GRUB would be a solution, but I'm getting a blue text-mode dialog that I believe comes from the shim, saying: Unfortunately the default Ubuntu-signed GRUB lacks modules such as http and tftp, and with Secure Boot on, it will refuse to load them from disk. I have a Wake-on-LAN situation where I'd like GRUB to make a network request to decide 'should I boot Windows?', perhaps by load_env (http,192.168.1.123)/grubenv (so I can write that file just before waking the machine).
