Hello! I have an old Mac from 2007 and it is blocked at 10.7 i believe (the one before lion or leopard) so I wiped it and installed ubuntu on it. I was dissatisfied with ubuntu and wiped the hard drive again. I would like to run windows 10 or 8 or 7 on it. I know it is possible to do it with this version of a mac since there are people that have done it on Youtube and forums. However all of these require bootcamp. Is it possible to install any version of windows between 7 and 10 that does not require any kind of os pre installed on the mac? If not, I can reinstall os x 10.7 or something and check if bootcamp is on it. I am not sure it is tho... Almost all functions on the mac are blocked by apple so I cant even run a safari update.
