I'm trying to install Ubermix 2.11L on some Asus EeePC 1000s. They currently have Ubermix 1 (don't remember exactly which version). I first tried option 1. Easy image system, but upon reboot, Ubermix 1 was still there. Option 3 Apply Simple Updates Files doesn't do anything, the menu just immediately reloads. I tried using 5. Expert options to 4. Reset primary disk partition map (destructive) before installing, and it still didn't work. Furthermore, Ubermix 1 was still installed, which tells me that resetting the partition map didn't actually do anything.
I read that some older Asus machines could benefit from creating a legacy partition map, but this is missing from "Expert options." Option 5 is set device hostname and option 6 is shell prompt.
