Creating Persistent LiveUSB-HDD

[Yora0]

Wait, step back! I have to rewrite the whole question.

Here's the new updated version of my question:

I don't have a USB Flash drive, but I do still have a 600GB external USB Hard Drive, which I want to use for the same purpose: Having Fedora 17 KDE in a small and portable device that I can plug into other computers simply to use the browser and text programs I am used to and also to make installations of Fedora 17 KDE on other computers.

Do I need a LiveUSB installation for that or a regular one? On a LiveUSB I always have "Install to hard drive" as a desktop icon and I can plug it into any computer. Is that a special LiveUSB feature that a regular installation would not be capable of (since it would have to scan the hardware and change configurations accordingly).

I assume I need LiveUSB, which faces me with the following problem:
Most LiveUSB creators do not recognize the USB Hard Drive as an eligible target for a LiveUSB installation. I found Universal LiveUSB Creator which has the options to list all drives, but that program does not provide me the option to make a persistent installation that can hold additional aplications I want to put on the LiveUSB drive.

Is there a trick to make other LiveUSB creators recognize the USB Hard Drive, or creators that provide both options?

Hi Yora0,

I don't think there is a way to run a install from a "normally" installed drive so you would need to use a livecd image on your portable USB drive to have that ability.

The solution may be "livecd-iso-to-disk" with regards to installing on your USB hard drive . That should allow you to create a bootable partition on your USB hard drive with the contents of the partition being a livecd. livecd-iso-to-disk is provided by the package "livecd-tools".

Hope this helps,
