Re: UEFI error: cannot allocate real mode pages

[Richard Chan]

I'm building and creating the image on a different UEFI machine (this one was booted from grub-legacy in UEFI mode).

As this stage, I'm clearly not able to affect the target's boot entries
but also don't want to "install" it on the source machine, since
they are totally separate machines.

On the target machine EFI Boot Manager
I can add an entry manually via browsing the USB drive.
This loads to the GRUB 2.00~beta command line.
The GRUB CLI seems to be fullly functional with regard to finding harddisks and ls'ing of  directories (ext2 and fat).
However it errors out at linux kernel loading.

I was preparing the EFI app off-box.

I do not have any OS on the target machine so I'm putting grub.efi on a USB thumb drive.

Is grub-mkstandalone lacking something?

Well it's not working, is it?

I don't understand why you are able to run grub-mkstandalone to build the .efi core image, but you can't use grub-install or grub-mkrescue.

You kinda need to be running this on a UEFI machine, pretty sure there's a dependency on efibootmgr which won't be present on BIOS hardware running Linux.
