Hello, I'm a beginner of ROS and Pioneer robots. The robot version is Pioneer 3-AT and the operating system is Windows with vs 2003. I've no ideas about how to change the operating system into ubuntu and install ROS with ROSAria. I have used both a u disk and a movable CDROM drive and the boot setup in bios was set to USB hard drive and CDROM but it still no work. Are there anyone has faced this problem before? Waiting for your answer please.

Thank you
