2010 live mode problem

[jtouso]

Asus EeePc 901 atom with 2 ram
Using unetbootin from windows to create an usb-pen with iso
All ok but finishing the live session a screen appears:

Error: No suitable media for the livecd content found
Workaround: Copy the content of the livecd from your boot device to an IDE/SATA disk
Dropping you to a limited shell
Loading /initrd/bin/ash
BusyBox v1.15.3 (2010-01-22)...
/initrd/bin/ash: cant access tty:job control turned off

Allways working with my usb-pen and unetbootin...
What is the problem?
Thanks

Me again:
Recording the iso to CD and trying with my cd/dvd to usb in my netbook and...same problem and message.
Trying again with unetbootin and other distros (Guadalinex, Puppy) and it is working without problems
What is happen with PCLinuxOS?
I read How to put on usb-pen with unetbootin in the forum, all the instructions but no working!
Help please
