I've done the process on a Dell Mini 9 with Snow Leopard 10.6.7 an the new tool "boot maker 1.0.0".
Unfortunately I haven't yet my Asus 1201N because i bought it from second hand and it is "on the road" to come here.
But the installation over an 8Gb USB stick went right (i think) because it says "succesfully installed".
Now I wait my PC and then i'll post if all went good (or bad )
Running on an ASUS P5Q-LE powered Hack (10.6.8) the Boot Maker 1.0. takes a few minutes - without any change to the USB key. Checking main HD shows a hidden temp folder... Can it be that any harm is done to my current installation (HackPro)?
But the 1201n is a fierce little machine - unlike my former Lenovo S10 (1st Gen)
