Re: Clone a bootable USB key
Indeed this is working. ( Test it with 2 identical USB-keys) But I think this is not a solution because the target usb is not the same size and make. It will work as long as the destination is as large or larger than the source. If the new key is larger, the added space will stay unused after the cloning, but you can recover it either by creating a new partition in this empty space, or by resizing the last partition.

Re: Clone a bootable USB key
Hi Adrian, Indeed this is working. ( Test it with 2 identical USB-keys) But I think this is not a solution because the target usb is not the same size and make. Thats why I copied the files and the MBR separately.( forgot to mention this ) What I am trying to do: I would like to make a copy of my USB-key to one or more files, send the files to a friend and he has to dd / copy this file to his USB-Key, and I was hoping this should work.

The MBR and grub are working but Grub does not know the sector location of the kernel, So it does not continue to boot. Use dd to copy the entire thing, it will work. dd if=/dev/sdb of=/dev/sdc Adrian -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Then what you have done previously will work on the proviso that you update grub to let it know where to find the kernel to boot. probably the easiest way for you to do this is to boot from the first working USB key and specify on the kernel command line root=/dev/sdc1 then as root run: update-grub -- 24x7x365 != 24x7x52 Stupid or bad maths? erno hm.
