I think I have seen this thread before but I havent been able to find it. I have two SATA harddrives, one with XP and one I just installed Vista Premium, all installed on an Asus mb. The computer always wants to boot to HD0, the one with Vista on it. The only way I can boot to HD1 with XP on it is to unplug the sata cable for HD0. Can somebody tell me an easier way to select which HD I want to boot to. Is there software or a command I could enter or is there hardware I could use? Please help?
