Hi. I have a Zoostorm laptop 8gb ram, Intel pentium. I bought it OS free and installed Peppermint 4 in the summer. Lately I have had booting problems. My laptop is connected to a powered usb hub with 2 external hard drives and has been from the beginning. Lately the the laptop will not boot unless I take out the usb hub. it has never done this before. The bios is set to Hard drive boot first then CD then usb, always has been. So why all of a sudden is it doing this?
