hi, i have 2 hard drives (c: and d, with windows xp pro installed on c and home edition installed on d. c is the master hard drive with d being the slave, and pro was installed on c before home on d. what i want to do is completely remove the old pro installation and just use the home os on d, using the c drive as a back up (and formatting it). is this safe to do now? is there anything i need to do before formatting? i'm just making sure the home install wouldn't be using anything (drivers, etc) from the windows that was already there that i'd need to keep. in case it matters, i get the option of which os to boot on start up, would home then boot automatically or would i need to edit my boot.ini? thanks!
