To simplify your tests...

If you have enough space on your /boot on your HDD, you can do the following:

[1] Copy your ONIE-live-XYZ.iso (or whatever the true name is) there from USB stick to /boot partition;

[2] Simplify the grub.cfg script like this:

menuentry "ONIE: Embed ONIE" --class gnu-linux --class onie {

  echo    "ONIE: Embedding ONIE ..."

  onie_entry_start

  set root='hd0,msdos1' ## hd0 is your HDD, 1 is /boot -> /dev/sda1)

  set isofile=/ONIE-live-XYZ.iso ## or whatever your ONIE... .iso image is named

  loopback loop $isofile

  linux  (loop)/live/vmlinuz $ONIE_CMDLINE_LINUX boot_reason=embed install_url=file:///lib/onie/onie-updater

  initrd (loop)/live/initrd.xz

  onie_entry_end

If this does work, U R Cool. But you need to have at least size of ~ 2GB for /boot (assuming your .iso is no more than ~1.5 GB in size).

This is why I ALWAYS assign to /boot (/dev/sda1) NO LESS that 2GB in space! ;-)

Hi Zoran,

Thanks for the info.

With previously attached grub.cfg + Vendor BIOS, I can able to install ONIE from USB.

But with  Coreboot + GRUB2 + previously attached grub.cfg, I am unable to install ONIE from USB. 

I am going to try your changes, I will let you know. 

Thanks,

Dhanasekar

Hello Dhanasekar,

This, I guess, is not (entirely) correct:

menuentry "ONIE: Embed ONIE" --class gnu-linux --class onie {

  echo    "ONIE: Embedding ONIE ..."

  onie_entry_start

  linux   /vmlinuz $ONIE_CMDLINE_LINUX boot_reason=embed install_url=file:///lib/onie/onie-updater

  initrd  /initrd.xz

  onie_entry_end

You should have something similar to the following:

menuentry "ONIE: Embed ONIE" --class gnu-linux --class onie {

  echo    "ONIE: Embedding ONIE ..."

  onie_entry_start

  set root='hdX,msdosY' ## hdX is your USB stick, Y partition, U R booting from, U should find going to GRUB2 monitor (with > prompt)

  set isofile=/<dir path>/ONIE-live-XYZ.iso ## or whatever your ONIE... .iso image is named

  loopback loop $isofile

  linux  (loop)/live/vmlinuz $ONIE_CMDLINE_LINUX boot_reason=embed install_url=file:///lib/onie/onie-updater

  initrd (loop)/live/initrd.xz

  onie_entry_end

Please, investigate a bit more using google.com! And let us know if you did solve the problem (post the final grub2 menyentry which works for you).

Hope this helps to the whole community. ;-)

Hi Nico,

Sorry, It is typo. I have tried with configfile (usb0)/boot/grub/grub.cfg only.. 

with a new boot/grub/grub.cfg, I am getting following error,

error: file '/vmlinuz' not found.

error: you need to load the kernel first. 

FYR, I have attached  /boot/grub/grub.cfg(which is present in USB). 

Thanks,

Dhanasekar

Read what Taiidan wrote carefully:

For a grub.cfg, it's a plain *configfile* (not syslinux_configfile).
