greetings, with this program, i understand that it i am able to run multiple operating systems on one hard drive. so, when it gets to the part that asks for what type of partition i want, which selection do i select (active, primary, or logical?). in the active, i have win xp home and only win xp home on the hard drive in one partition and no others. i have made a "recovery cd disc" as it suggested. i want to install win- -me on another small partition of 10gbs and not get locked out of my win xp home. then, there is an issue of formating that partition for the installation of win me.... also, when i boot up my computer, will i be able to manually select what os i want to use? thanks!! i do not want to lock out or damage my current installation in any way.....thanks for any assistance you can give! edit; if i am successful in doing this, will i see a c+d (or whatever) drive letter in "my computer"? ANOTHER EDIT!...i have managed to get to the point where i have created a fat 32 partition on my hard drive and have installed the boot manager. i have selected teh boot manager to boot from the floppy drive of which i have inserted the start up disc for windows mellenium. the cd rom drive has the win me operating system disc inserted in it also.***this is where i get confused! when the win ME starts up and wants to install, i get a message that says that another os has been detected and that if i go farther with the installation, it will over-write or render that os inaccessible (if i understood what the message was). what did i do wrong and how do i get past this w/o affecting my current win xp home installation or partition?...thansk again.
