i dont have a disc that include 3 version of windows, are you crazy

each of them is different discs. mostly i tried with usb stick (i tried and succesfully installed windows 7 before several times ). i used win2flash for bootable usb. but problem is not windows version or discs.
i ve already tried section 6 -7 rroad. it is interesting.
i deleted all space and i tried to install(1 partition)
i deleted all space and formatted Hdd and i tried to install(1 partition)
i deleted all space and i made 2 partition 30+40gb space and i tried to install...
i dont exactly remember the way which i did experimental but each technic's warning is same YELLOW WARNING bottom of the disk management dialogue!
i ve about 13 years experience of windows and i really hate this system. i think windows's stableness isnt enough even today!
