please, can you try this method? http://forums.debian.net/viewtopic.php?f=17&t=48602 dd if=musix.iso of=/dev/sdX "It will destroy all partitioning on your usb drive and set up everything automatically. E.g. 1GB flash drive will have a 700MB partition with the Debian installer or Livecd and then you will have 200-300MB space to create another parition." make sure you will write to your pendrive USB and not the HD during the dd copy of the iso, please.
