Creating boot USB flash drive
I have a copy of Knoppix_V7.0.4DVD-2012-08-20-EN.iso which I downloaded and used to create a boot DVD using Nero. It works fine on both an older ASUS computer and a recent Gateway machine. The ASUS BIOS does not allow USB boot but the Gateway does. How should I go about creating a boot USB flash drive on a 16GB CoreMicro flash drive
flash-knoppix is Your friend!
Nothing against Tools like Universal-USB-Installer, LiLi or unetbootin - But it's better to use the flash-knoppix program included with Knoppix. That one can create a LiveUSB-Installation on a big enough flash storage device. This means: Using a persistent overlay file system on the flash storage, one can have a portable system, remembering all changes (i.e. data files, user-installed Debian software) across reboots and computers!
By choosing to boot from such a flash storage device without the overlay file system mounted, one can still use it like a LiveCD or LiveDVD system (without personal changes). The persistent overlay file system can even be password-protected/encrypted, making a flash storage device with private data sharable with other people.
This works even better with newer Knoppix releases, allowing one to fill a >= 16 GB flash storage device with the 4.3 GiB KnoppixLiveDVD + 10 GiB personal stuff (by using flash-knoppix2, the experimental installer).
