don't know what you're doing with the /c
what i did to mount jailbait 6, and i did it several times, so i do know it worked.
i plugged the harddrive in with dolly. i think in the bios only c: is designated as boot, no other was in there for the order.
i then got into a command prompt by boot up the harddrive and keepping the f8 key which would be the 8th key on top of the io keyboard.
once at the prompt, i'll run the dolly program such by this command dolly jaibait6.img 129:
something like that. basically putting the jailbait image to the 129 which is the 2nd disk and this being the sandisk.
then, i'll reboot, and go into the bios to change the order of the boot to d: or the sandisk instead.
you'll have to use a regular keyboard and hit the control alt and esc keys.
good luck hombre.
