this is not possible - ISO must be burned on a block device.
why would you like to boot from the ISO?

[maerz]

1. Target: Quickly update iso and boot. (add new module kiosk, create new iso ,del old iso, copy new iso and boot)
2. two
burn iso kiosk to hdd
dd if=/root/kiosk.iso of=/dev/sda
create only one partition /dev/sda1
boot and same problem

Code: Select all

please, any resolution...

1) "Quickly update iso and boot."
possible but only through PXE boot

2) you can burn kiosk ISO to a partition instead of the device:

Code: Select all

dd < kiosk.iso > /dev/sdb2

but then you need to point 3rd party bootloader (like Grub) to vmlinuz and initrd.xz
This method works for sure as i'm using it often.

1. Not use PXE. only WI-FI. only one internal web site.
2.
2.1 create sda1/boot/grub and boot
2.2 create sda2 fdisk, size 96 MB
2.3

Code: Select all

dd < kiosk.iso > /dev/sda2

error:

Code: Select all

grub> root (hd0,1)
Filesystem type unknown, partition type 0x83
Error 17: Cannot mount selected partition

bug?

grub.cfg & menu.lst

Code: Select all

timeout 30
title kiosk
root (hd0,1)
kernel /boot/vmlinuz
initrd /boot/initrd.xz

there is something wrong with your grub as it does not support iso9660 filesystem. please try other bootloader like extlinux.
