There use to be sub-forums, those are gone with the new "Communities"
I have a lot of peeves with "95%" support for "Windows on Mac" to replace the name Boot Camp which is and should be reserved for :
Boot Camp Assistant - to assist in partition and install
Boot Camp drivers - as the name implies
GPT supports an MBR, there is always a 'protective MBR' already.
BCA just expands on that slightly.
There is no running the OS under anything, unless talking about VMs and Guest OS.
Windows runs native, pure and simple but without the BIOS which was replaced with UEFI, which is now found being supported on some newer PC motherboads, often as a hybrid.
UEFI and GPT go hand in hand. Booting GPT requires EFI and Intel/MS and Apple officially adopted a UEFI standard late 2007 for 64-bit kernel boot mode, for MS starting with Vista SP1 64-bit in 2008. The Mac Pro Early 2008 was the first Mac with full 64-bit UEFI too.
Apple motherboard drivers? peeve.
Installing graphic drivers: seems like it slowly is getting easier and better to install those now, may require Boot Camp driver 4.01+.
Just that Apple chargers $30 for the drivers. peeve.
Boot Camp 3.0 - came out Aug 2009 barely built while Windows 7 RC was winding down and 'frozen' but not RTM even - and why "3.1 req'd for Windows 7" but did they replace 3.0? No. Can you install one time only 3.3 as a full set? No.
So the drivers are locked into Lion and Boot Camp Assistant.
Macs rely on SMC/EFI for thermal management of fans which does not work when the MAC is running Windows.
And that is what people seem to mean with "Mac running under Boot Camp" which implies something else.
That is why heat and cooling are more of an issue and a real problem even now running Windows.
SmartFan is a nice Windows utility and I kept hoping for years it would be possible and "ported" to work on Mac motherboards, but never seen it. "InputRemapper" though would allow settng fan speed on MacBook and Mac Pro, was created in May 2007 and to my knowledge is the only thing that helps the fans but has not been updated since - maybe it doesn't need to
Any software though is 3rd party and while some basics, really there has been little of the in depth discussion.
Apple has a disclaimer of how far their support for Windows goes. The old AD forums had install, network, applications, Bonjour and Apple SU (both are still present).
Games, Office for Windows, no.
3rd party audio, network and graphic drivers, yes.
HFS drivers, and programs to backup or image and restore Windows, yes. Unique to Macs and PC programs don't usually work so assume no unless otherwise and that is unique.
Other than Windows always needs drivers for motherboad support, to support chipsets and such, a Mac can be 100% Windows only.
Shorter battery life, runs hotter, BT keyboards and wifi are more likely to be issues. And can't boot into BIOS to adjust hardware. And no F10 (or 12 or whatever) to bring up, but there is Alt boot manager. Apple adds OSswitcher and TimeSynch to handle those two services.
No customized "speedfan"
Programs and drivers that try to detect the hardware or read from (BIOS) firmware
