سؤال مهم جدااااااا ....

كيف تستطيع وضع أكثر من ويندوز في كمبيوتر واحد ........

So easy, man.
when u try to install the new version of Windows, there is somethin in the instruction called express installation or "Advanced Installation"
First of all you, you should have an empty partiation, each operating system needs one partiation, a sperated partition.
when you install the windows, make sure u read the first instructions and find the Advanced Installation.
Warning_____ if you want to install two different versions of Windows, for example (ME and XP) you should first install the ME version, because XP and 2000 can not take an earlier version of Windows while ME, 98, 98 SE, and 95 can.
hope i could give you some good informations.
