Hi Marcus,

now, u-boot lists all bootable partitions to look for boot scripts. If no partition has a bootflag, it falls back to 1st partition. This break Chromebook (and maybe Raspberry Pi?) images, since 1st partition is hidden and we use partition 2 for our boot script, kernel and initrd.

Could we add the boot flag to partition number 2 when vboot is used?

We should be able to do this in out u-boot-install and first boot script, no? Alex

I can look into this, could you send me the current partition layout parted <device> unit s print Thanks Regards, Marcus -- Public Key available via: https://keybase.io keybase search marcus_schaefer ------------------------------------------------------- Marcus Schäfer (Res. & Dev.)

Boot flag is for #2 : lxboot.

Thanks, ok I can certainly set the boot flag to lxboot. However I'm concerned that this table has no boot flag set at all while I'm sure kiwi does set it to one partition. The 'U-BOOT' partition seems to be changed/added by your custom scripts and I suspect this fiddling with the partition table cleaned the boot flag. Because of that I fear even if I change the code in kiwi to set the boot flag to the lxboot partition it will not end up in the final image due to the post processing scripts we maintain in the various image descriptions I have not verified this though Regards, Marcus -- Public Key available via: https://keybase.io keybase search marcus_schaefer ------------------------------------------------------- Marcus Schäfer (Res. & Dev.)

Boot flag is for #2 : lxboot.

Plase also keep in mind that we're manually creating a hybrid GPT with an MBR reflecting most of the layout. I don't know which label type u-boot prefers in such a case - Linux will use the GPT.

u-boot too, I think.

The reason this is important is that the hybrid GPT bits are in our scripts, not kiwi.
