Tosh: Actually, I figured out how to do it: 1. Using fdisk, I created two partitions on the drive: /dev/sdc1 = 15 MB /dev/sdc2 = The rest I marked the first one bootable 2. I used dd to copy the diskboot.img to /dev/sdc1 3. Formatted /dev/sdc2 as ext3 and copied the iso images there 4. When I boot from the usb drive, I selected hard drive install and pointed the installer to /dev/scd2 It worked perfectly!
