Yes, I have installed dual boot loader with beastpatcher -d .
The problem is when I unplug usb cable, s30 go black screen, so I have to turn bat off and on again.
After i turn batt on, it go to recovery mode and delete all my data.
After that, I have to format data disk before copy .rockbox (if I not format, "File not found" happened).

if yes, what is "/path/to/partition/device"if my data drive is f:?
