Win 7 is the best os at present.everyone likes to use it.but for some reason xp is needed by people for many things.in my case,i wan win 7 for best look and easy work and xp to install game and other softwares requiring more ram.But i want something different too.Xp and windows7 feels same.And to have something new,Ubuntu is the best option because it is the free os.triple boot is not just for fun but very hlpful; in many cases.I installed deep freez in win 7 to protect my files and used it in all the drives even in the drives with xp and ubuntu installed.But deepfreeze is very probematic when you want to change files and other settings.Say if you want to copy files from usb then you have to thawed depfreeze for next use then restart then copy and then restart again.restart twice is boring.but i can just go to xp or ubuntu in first log on and copy files without restarting for nce.also disabling and uninstalling deepfreeze becomes piece of cake wih triple boot or dual boot.I promise I'll show you how to do these things and even triple boot with no risk of damaging harddisk and your drives.
first of all you need to create separate partition for each os with size as follows
vista :16 gb {if you don't have to insall too many softwares requiring large hd space,else, 30 gb is enough]
win 7: same as vista
xp:depends on xp but 16 gb to 20 gb will work fine for all xp(xp i installed required 12 gb of free hd space)
ubuntu:10 to 12 gb is enough.(in case you have some private files you don't want others to know about then
keeping it in ubuntu partition is best option for it won't be visible in win 7 and xp.so you can add the size depending on the size of those files).Creating the new partition is very easy if you are using win 7.But you need third party sofwares if you are using xp.but you can create parition while booting with xp so you don't need to create them before.you can see how to create partition from win 7 in my other post.
