(adsbygoogle = window.adsbygoogle || []).push({}); Hey guys. I have a quick question. I want to install Windows on my Mac but im afraid if I do, i'll "erase" or "lose" my actual mac os I paid for. Like, if I install Windows, will I just have Windows only on my Mac or will I have Windows AND my Mac I paid for also? SO, will I only have 1 or 2 os's?

You will run both os's separately if you use a partition through parallels or boot camp.
follow the tutorials perfectly when i did it the first time i forgot to select the mac os as start up so my computer was trying to start up from the windows partition. Wasn't a pretty site.

I installed windows a couple times you do not want to do it makes your mac lag .

make a partition using disk utility than you wont lose anything!
