Hi ... I have 4 hard drives install on my computer , what I have done is basically installed windows 2000, xp and 7 on separate hard drives , each windows was done on itself without any other hard drive install . So basically one hard drive listed in the bios for each windows , yes I know I have an extra drive . So my question now is when I hook up all the hard drives together will I be able just to select from the bios screen which drive I want to load ? In other words I want to be able to go back and forward in the bios screen and choose which Windows I want to load . Will this work ? Thanks
