I downloaded Ubuntu. What I would like to do is dual boot it on a 2nd internal hard drive. Both drives have SATA connections. I know how to install an operating system but I haven't done it with 2 systems before. I guess I should unplug the power connector from the XP system first so there won't be any confusion to where the Ubuntu files should go. Is this correct? If anyone can send me a step by step guide that gives EXPLICIT instructions that are easy to follow I'd greatly appreciate it. I'm a total newb to Linux but I'm an above average computer user. Thanks.
