Live gnome-cd to create an usb install piece

I am trying to create an usb install from an gnome-live cd.
All I have done is not working:

dd
fedora liveusb-creator
fusbi
linuxlive usb creator
unetbootin
pendrive

All I can get are errors saying cang find kernel or error like that.
I have used linux and windows environment.
The iso I am using is fine, I am sure because I have instaled it on two pcs.

Anybody can give a howto tested for this?
Iso gnome-live >> usb (bootable to install)

Thanks guys

Final solution to this.

1.-Download an .iso (I have used gnome-live)
2.-You will need a usb stick ( 1G will be fine)
3.-Create a “live usb” using netbootin ( UNetbootin - Homepage and Downloads )
4.- here is the trick…
When usb is created, you will see something like 0x55274ed8 in the file /boot/grub/mbrid
This code is taked from your hard disk. When your usb is trying to boot will check if that code is the same with the disk booting (I mean, this time it should be your usb code). The problem here is the installer just copy the code from hard disk.
The solution is, insert your usb and run the command fdisk /dev/sdc (thats my usb stick, yours can be different), then “p” (print partition status of usb disk). Now check for “Disk identifier: 0x3b3436e1” (of course, your identifier is not the same). Press “q” to quit.
Now go to your usb and change the identifier using your usb identifier.
Save changes.
Reboot.

Smile ! You can boot your usb and of course, install from usb if you want
