Zubuntu On A 4gb Transcend Sd Card, Issues with a new card Options

[ofels]

Until today I used a Sandisk ExtremeIII SD card with 2.0 GB to run zubuntu via kexecboot kernel which worked like a chrm.

Today I formatted a 4GB Transcend card with ext3 and installed zubuntu on it. The result is somehow demotivating- themultiboot kernel starts, probes mmcblk0p1 and then returns with "no bootable device found". The boot flag is set on the partition.

I tried several things to solve the issue- shrink the partition to 1 GB, copied the root filesystem from the 2GB card- same result.

Interesting: Starting with the 2GB card until the multiboot display appears and then exchanging the SD cards works. So it is not the card itself, propably.

Any clues or similar experience?

Perhaps an obvious question, but does the SD card contain a partition? I think I might have accidentally used SD cards in the past without generating a partition.

If you fdisk /dev/mmcblk0 and select 'p', what does the partition table look like? For reference, my SD card contains three partitions and looks like this:

CODE

Device Boot Start End Blocks Id System
/dev/mmcblk0p1 1 353 2835441 6 FAT16
/dev/mmcblk0p2 354 484 1052257+ 83 Linux
/dev/mmcblk0p3 485 492 64260 82 Linux swap / Solaris

Kexec can pick up a kernel on the second partition; I just have to ensure the boot directory contains the files image.nfo, kernel-cmdline, zImage.

Of course it does
I once had two partitions on it but reduced to one to eliminate this as a potential source.
