I haven't tried doing the above yet, because in case of failure I would have a non-working computer so I want to make sure before I do it 😛.
I've installed Windows on PCs countless times and I'm aware of the fact I can modify the partitions there, but my worry is EFI.
AFAIK Boot Camp does some stuff connected to EFI BIOS emulation or something like that. Will the computer work without this if i just delete everything on the drive? Has anyone tried this?
Matek, BootCamp is not necessary to install Windows as the Primary OS on a MacBook, EXCEPT for the purpose of creating the Macintosh Drivers for Windows disk, which is absolutely necessary, unless you already have such a disk made which includes latest updates.
Once this disk is created, all you would have to do is
1) Insert Vista (Or XP) installation Media
2) Recycle power
3) At Gray Boot Screen, choose to use the drive containing the Windows installer as the boot drive
4) Proceed with Windows installation, making sure to delete ALL partitions (including the EFI partition), then create a Primary partition upon which to install Windows. I suggest a MINIMUM of 40GB for XP, or 80GB for Vista. No need to delete HFS+ DATA partitions, but do delete the system partition as well as the EFI partition before repartitioning for Windows.
Once you are dumped at the Windows Desktop, replace the installation media with the Macintosh Drivers for Windows installation media and start the installation.
Then it will probably be a very good idea to access Windows Update for the latest updates, including Service Pack 1 (Vista), or Service Pack 3 (XP).
I have done this several times on two Apple Intel iMacs, each time successfully, and without trouble. This leaves you with a stable Desktop, and is an excellent hardware base for Windows.
MacDrive is an EXCELLENT tool to obtain (and well-worth its modest price), and will enable you to access your HFS+ data partitions transparently, for writing as well as reading. (Don't forget that your Mac executables will not be usable in Windows. But the data is usually interchangeable with little trouble.
Also, DON'T FORGET to install good-quality (i.e., "commercial, NON-Microsoft") third-party Antivirus/Security software. It is easy to forget the international shame of Windows security after running OS X for a few years.
*** IMPORTANT NOTE !!! ***
Doing the above will require OS X to be reinstalled if there are important Firm-ware updates you must install after the conversion to Windows. Don't forget to keep your Windows Data backed up externally if you need to return to Windows after installing needed Firmware updates. Also, from time to time, Apple releases updates for the Macintosh Drivers for Windows (not often enough, in my opinion).
