I was following the steps here ("Preparing Files for USB Memory Stick Booting")

• https://help.ubuntu.com/10.04/installation-guide/i386/boot-usb-files.html

to create a installation usb drive for 12.1. The very first paragraph of the article states

• "The second is to also copy a CD image onto the USB stick and use that as a source for packages, possibly in combination with a mirror."

However, the only instructions mentioned regarding an iso image is to simply copy one somewhere on the drive (after its been made bootable and syslinux, vmlinuz and initrd.gz installed/copied):

• "you should now copy an Ubuntu ISO image onto the stick."

I thought it strange there where no configuration steps for "pointing" the kernel to the iso (like a line in syslinux.cfg or a boot: option or something), but went ahead with the install anyway.

I don't think the iso was used at all, it appeared that all the OS files where downloaded during the install process.

Therefore, I was wondering if anyone knew how to use this local iso image in this particular installation technique (I know the image can be installed with dd, but thats a different technique), b/c I need to reinstall (I installed unity, but it's wayy to much for my little Atom based netbook) ?

Thank you.
