Thanks for verifying and your feedback, Daniel!

that works perfectly.

I copied the /boot/efi.img file to the grml 2014.03 bootable USB I had made
and it resolved the EFI booting issues.

Thanks.

Hi,

I've just verified this for the most recent build of grml64-small (being
https://jenkins.grml.org/job/grml64-small_sid/881/artifact/grml_isos/ as of
now), works as expected with grml2usb 0.14.4 (verified the result via
"qemu-system-x86_64 -bios /usr/share/ovmf/OVMF.fd [...]"). This is a problem of
the 2014.03 ISOs (which I just verified, got the same error message as you)
which lack the bug fix for UEFI boot which is included in recent grml-live
versions
(https://github.com/grml/grml-live/commit/8d91fa8e1b3b6d46a1333928a7384a463868cce0),
so all the new Grml builds should be working just fine.

regards,
-mika-

That solves the booting from a dd'd USB disk , but a disk created by
grml2usb still has issues booting. Copying the files from 13.09 that i
mentioned earlier fixes it.

Daniel, could you please be so kind and give one of the http://daily.grml.org/
ISOs that will be available as of tomorrow a shot? We have a pending fix in
https://github.com/grml/grml-live/commit/8d91fa8e1b3b6d46a1333928a7384a463868cce0 which
hopefully addresses your issue and the ISOs that are available as of tomorrow
(2014-05-09) are supposed to include that fix.

only tried with the grml96 flavour

I got grub/uefi booting working by copying the /efi/boot/bootx64 file from
GRML 2013.9

Hm, this could be related to
https://github.com/grml/grml-live/commit/d3e8ff25fa98d39f794af4c8c151ca17f110bc6b -
are you able to reproduce the problem with the grml64 flavour as well?

Seems as GRUB boot mode is broken for USB disks.

If i create a grml USB disk usingthe --grub option it doesn't boot at all.

e.g.
grml2usb --grub /lib/live/mount/medium /dev/sdb1

From mucking around in the grub rescue mode it seems as it doesn't have
msdos filesystem support.

Have tried two methods to boot USB disks using EFI/UEFI
### 1. USB disk created using dd cdrom.iso > usb disk
What steps will reproduce the problem?

create usb disk by using dd/ddrescue onto a usb flash drive.
in my case i used the following command after booting from the grml CD

ddrescue --force /dev/cdrom /dev/sdb


What is the expected output? What do you see instead?
For PC and MAC (imac)
  no UEFI boot option appears for the usb disk (grml 2013.9 installed to USB
disk works fine)


What version of the product are you using? On what operating system?

Using grml 2014.03 full 96
On a newish PC that allows UEFI as well as legacy booting methods.

### 2. USB disk created using "grml2usb /dev/cdrom /dev/sdb1" to usb stick with
formatted fat32 partition
What steps will reproduce the problem?

make USB stick and then try to boot from a MAC or a PC with UEFI capability


What is the expected output? What do you see instead?

On PC& MAC the drive appears and shows it has EFI/UEFI booting capability but
when you boot the following error occurs. (within the """ delimiters)

"""
unknown command 'normal'.
E: Could not find root device!
Error: no such device: /conf/bootid.txt
Entering rescue mode...
grub rescue>
"""

What version of the product are you using? On what operating system?

Using grml 2014.03 full 96

On a newish PC that allows UEFI as well as legacy booting methods.
