This first step is quite useless. The dd run to put the ISO onto the stick will overwrite the partition table. You should rather consider to make a backup of the whole stick if its content is of any value: dd if=/dev/sdX bs=1M | gzip >backup_of_sdX.gz > Assuming the bootable USB > drive has enough capacity, as most do nowadays (13 GB should suffice), > can the second and third ISO files be saved to the same USB drive? The main problem will be with telling Debian that the ISOs contain packages which shall be installable. Maybe https://wiki.debian.org/SourcesList is an entry point for exploration. Maybe other users here can give examples. For storing the ISOs on the USB stick you need one or two new partitions after the first ISO was copied to it. The stick will then already have two MBR partitions, like $ /sbin/fdisk -l /dev/sdc ... Device Boot Start End Sectors Size Id Type /dev/sdc1 * 0 7798783 7798784 3.7G 0 Empty /dev/sdc2 20216 21047 832 416K ef EFI (FAT-12/16 The partition editor fdisk is tolerant enough not to take offense from the type "Empty" of partition 1 and of the fact that partition 2 is inside partition 1. It will also ignore the (invalid) GPT and its backup at the end of partition 1. The actual choice of partition layout depends on your solution for the problem of presenting the ISOs to Debian, You could create one partition that covers the rest of the stick. This would be formatted with a filesystemi. The two ISOs would be put into the filesystem either as two big data files or unpacked into trees of the ISOs' content files. Alternatively you could create two partitions, each of the size of one of the ISOs. Then you'd put each ISO as filesystem into its own partition: dd if=DVD-2.iso of=/dev/sdX3 dd if=DVD-3.iso of=/dev/sdX5 (I assume you'd use partition 4 as extended partition and create logical partition 5 as storage for the DVD-3 ISO.) Have a nice day :) Thomas
