I want to install Vista on a separate hard drive from the one I have XP installed. I want to be able to change the boot drive in my bios to use either operating system. The hard drive in question has two partitions. One partition has nothing on it. Can I install Vista on the partition with nothing on it without damaging the info on the other partition? Please excuse if this question has been asked before as I can never get the search engine on this site to work worth a darn. Thanks for any response.
