Do you know what is needed to enable secure boot with grub-efi? So having read your clarification below, I assume this question is about grub-efi specifically.  I might have been overly specific with my original report but I would like to boot (uefi with or without secure boot) with any boot loader, not necessarily grub-efi.  I have no idea how this is done with grub-efi specifically - some Ubuntu docs suggest that they use a Microsoft-signed shim loader that operates before grub-efi. >>> That means you can't just take an operating system hard drive from one >>> EFI system to another. >> I'm absolutely not an expert on UEFI, and it's likely I'm >> misinterpreting some of the more subtle points you wrote, but do you >> have more information on the NVRAM restriction?  I've found a fair >> amount of references to making secure boot and UEFI capable media (USB >> and CD) around the web so I'm surprised it's not possible to make a >> portable UEFI image.  Wouldn't that make it difficult to install UEFI >> bootloaders on blank systems? > To clarify: "grub-efi" will not work to make a portable UEFI > installation.

Ah thanks!  I was indeed misunderstanding some of the subtleties in your previous post, and thanks for the pointers.  Depending on how straightforward it is I might try my hand implementing it, time permitting, but it probably wouldn't be for at least a month due to other priorities.
