Re: won't boot with USB hub pluged in
Check the boot order in your BIOS to see if bootable USB devices are checkup upon startup.
If you can, either disable the BIOS from checking to see if bootable USB devices are present, or make sure that the hard drive with the OS installed is set to boot first.
