Problem: Getting Debian Squeeze installed onto a PC or in my case, an HP T5520 thin client with out an external USB CD/DVD-ROM drive.

While you can use one of the many tools around to copy the ISO image to your USB stick and make it bootable, the Debian installer gets hung up on not being able to find a CDROM drive or device to mount.

Solution in a nutshell: Create two partitions on the USB stick, on the first partition use the Windows pendrivelinux installer tool to copy the ISO and make it bootable. Extract a copy of the ISO to the second partition.
