Hi, I have today received a copy of Windows 7 Home Premium, and am looking forward to installing it on my MacBook (early unibody version with Core 2 Duo processor, recently upgraded to Snow Leopard - version MacBook 5,1 - with 2.4GHz Processor and 4GB RAM). The question is simple, but I am utterly confused when searching for the answer...! Should I install the 32bit or the 64bit version of windows? (both the disks are in the box). I would like a smooth installation, and realise that 32bit should work no problem. However if all the drivers are available for 64bit windows, and it works then I see no reason not to install that version. I am confused because there is reference on the Apple website of this version of the MacBook not being supported for 64bit despite having a 64bit processor (??) Also the vast majority of the information on the Apple website seems to refer to Vista 64bit. I imagine that this will be quite confusing for many users, as it has been for me! Please advise as to the correct way to proceed. Ideally I will only install windows once, and would obviously like to install the potentially faster OS if it will be straightforward, and everything will work as it should (have read about problems with the iSight/backlit keyboard etc. - but these may now be fixed). Thanks in advance.
