Hello All, I have installed Vista on a second partition using Bootcamp and all works fine until I plug in my USB powered hub which has 2 External HD's and an external DVDRW. If I have the USB hub plugged into the iMac and try to start Vista, it locks up at a white screen. If I unplug the USB hub from the back of my iMac and try to load Vista it boots correctly. Once booted into Vista I can plug my USB hub into the iMac and all my drives show up as normal. It appears as maybe there is a boot conflict when the ext HD's are connected? What should I check in windows or in Bootcamp? Thanks in advance.
