[SoaS] Mango Lassi USB Boot issue

[Rajiv Bhushan]

I just use Unetbootin to write the latest Mango Lassi ISO on to a 4G USB 
stick.

I booted onto a Compaq and a Toshiba laptop, and After the initial 
splash screens, the boot process stops, and I get the following message

(Note '----------' indicates begining and end of message or file)
---------
No root device found
Boot has failed, sleeping forever
---------

On examining the files on the USB stick

in the /efi/boot folder, boot.conf is as below

--------------
default=0
splashimage=/EFI/boot/splash.xpm.gz
timeout 10

The ubnpathl.txt has

These are the only files that appear to be editable.

Any ideas as to how to get sugar to boot?
