Linux install/Dual OS boot HELP ME PLEASE!?

[chrisw]

hi I want to put two OS's on my computer so that when I start I have the option of either windows or linux or Mac...

Is this possible?

If it is possible will it delete all my files?

And one last thing if it doesnt delete it all will it merge it all into the other OS...

For example will i have all of my downloaded songs on Linux aswell as windows as soon as I install?


THANKS!
