While I can not help you directly, I did install this image under qemu. Here is what I did (more or less): 1. install the image as you did (I have installed it on external USB stick) 2. mount /dev/sdb1 /mnt #(my USB stick), 3. cp /boot/vmlinuz26 /boot/kernel26.img /mnt/boot # copy kernel and ramdisk image from my desktop 4. # modify /mnt/boot/grub/grub.conf to include the newly added kernel 5. grub-install --no-floppy --recheck --root-directory=/mnt /dev/sdb So I was able to boot using my original kernel. Then I also used: rdev /mnt/boot/vmlinuz-2.6.29.1-18.1.moblin2-netbook /dev/sda1 to change its idea about the root device, and so was able to boot it (but then the X session did not run for me - and it is another story). I was able to modify the original kernel image to boot, but I should mention rdev's manual page (created back in 1993!): "The rdev utility, when used other than to find a name for the current root device, is an ancient hack that works by patching a kernel image at a magic offset with magic numbers. It does not work on architectures other than i386. Its use is strongly discouraged. Use a boot loader like SysLinux or LILO instead." So in general, it looks like a bootloader problem. You could try to use syslinux or lilo instead of grub. And finally, I should mention that if you created your boot partition as ext4, and the original kernel has no support for ext4 compiled in, then you will get similar error (I got it too).
