[Alpha 1] ISO does not boot on UEFI machine

[Erich Eickmeyer]

I attempted to boot the .iso file on my EFI machine and... no joy. Upon investigation, it appears that EFI bootloader files and folders are missing from the .iso.

As such, I would be happy to work on and implement the necessary bootloader so that EFI machines can boot the .iso.

Erich, that for the report. It could be because we are not build from official seeds yet and therefore some of the boot loaders are not present in the live session.

I'll review what is install on stock Ubuntu and try to mimic that in our custom livecd-rootfs package. If you have any indight into what EFI boot loader you'd use then package names are useful. I have no EFI hardware.

[Erich Eickmeyer (eeickmeyer)]

I do have EFI hardware, which is why I volunteered to do development and testing. If we are to mimic the Ubuntu EFI bootlader, then it's GRUB2.

As such, I'm no stranger to this, as I am the developer of the Ubuntu All-In-One DVD (EFI version), the Linux Mint All-In-One DVD (EFI version), and the Linux Mint Debian Edition All-In-One DVD (EFI version). None of those are "official" projects, but I'd be happy to use my skills here to help in whatever way I can. :)

Erich, well I could use the help. Can you tell me, do Lubuntu and Xubuntu 14.10 boot on UEFI hardware?

[Erich Eickmeyer (eeickmeyer)]

Lubuntu and Xubuntu both successfully boot on UEFI hardware.

Attached is a .tar.gz file with the necessary EFI boot files extracted and modified (slightly) changing the name of files to ubuntu-mate. I commented-out the sections in the grub.cfg file that do not work (yet). The files/folders in this archive simply need to be extracted to the root (/) directory of the .iso to make it boot on an UEFI machine.

Boots fine on my asus x501U with UEFI enabled.

Created a USB stick from the iso with unetbootin. It boots fine for me on my asus board.

The only thing is that the USB stick showed up as "UEFI Default" in the boot menu.

Testing indicates that it is now possible to boot a development release of the amd64 iso on EFI hardware, in most cases.

However, the iso doesn't support SecureBoot. SecureBoot support will only be added when the Ubuntu MATE project achieves "official flavour" status and the iso images are built on the Canonical infrastructure.

This is as good as it get for now.
