Is the partition table valid after you used dd to copy it over? If it isn't, try mounting the livecd. You might find a boot.img or something. This will vary though depending on the ISO you find. I ran into this with Crucial's boot disk for flashing (isolinux). I did dd bs=4M if=blah.iso of=/dev/sd? mount /dev/sd? /mnt/gentoo cp /mnt/gentoo/boot/boot.img ~/ umount /mnt/gentoo dd bs=4m if=~/boot.img of=/dev/sd? You'll have to update the device file accordingly. After I wrote the boot.img found within the ISO I was using, I was able to boot from the USB. Your mileage may vary. Sometimes dd works, sometimes it needs extra steps. Dan
