Hi guys, would be most grateful for help with this. I picked up an emachine, EM350, for my daughter. Seems in excellent conditon etc, but, there is no op sys on there. As this has no CD rom, then, I'm hoping to add my win xp using a usb pen. One problem. I need to set the boot order to see the USB first. Unfortunately, I am unable to do this. Going into BIOS, I can see the options I have, and the USB pen is viewable in the options, but, for some reason, I am unable to select any of the options. Seems that for some reason, the boot order can not be changed. There is also other stuff in the BIOS that I am unable to change. Any ideas?
