Hi,
I have an USB key and I would like to know how I could `burn' a .iso
image on it. I remember some weird procedure using dd, but I'm not sure,
and I can't find the tutorial. Evidently, assuming respective BIOS
capability, the USB key should be bootable.
You don't say "WHY" you want to burn an .iso file onto a usb stick.
The debian installer recognises the .iso file and so if you are making a
debian install usb you set it up on a standard VFAT formated memory
stick (mostly the ones you buy are already formated like that) and just
copy the .iso image on to it.
If you are NOT doing that, it is possible to get at the raw files by (on
your hard drive) mounting the .iso image using the loop device using a
command something like
mount -o loop myisofile.iso /mnt
and then the contents of the file will be available in the /mnt
directory (as the directory hierarchy in the .iso image.
You just copy them to the usb stick.
If this iso image contains a kernel etc
then take a look at syslinux.
This enables you to boot a kernel from the vfat filesystem.
EIther boot a kernel image and its initrd from the installer (the initrd
image kicks the install process off), or in the second case boot the
image you find on the .iso filesystem
