How to convert a iso9660 ISO to a USB ISO?

[Steven Truppe]

Hey,

i only know how to make a USB bootable disk with this iso, you can also 
mount the iso with fstab and burn the content to a CD maybe.

To create a bootable usb-disk you only need the "dd" command:
1) make sure the usb disk is not mounten
2) To see a progress bar install the "pv" package (sudo apt-get install pv)
3) Open a root terminal
4) dd if=/home/username/yourisofile.iso | pv | dd of=/dev/sde (the 
/dev/sde is the mount point of your usb-disk - you can find it easily 
when you first plugin the device and then type "dmesg". But after that 
DON'T FORGET TO UMOUNT THE DEVICE > umount /dev/sdX)
5) Be very carefull about the /dev/sdX device name, otherwise you will 
overwrite another device that is plugged in !!!!)
6) Enjoy your fresh bootable usb-drive

If you need a bootable CD use "InfraRecorder", it let you burn .iso 
images to CD's, this way is the way if you need a bootable CD - use the 
"write ISO image".

Hope this helps.
