Never did Hackintosh before, need to triple boot, where I start?

[OrSpeeder]

I own a MacMini, and I use it solely to work on contracts when people want it (otherwise I prefer to use Linux)

 

I bought parts for a new computer after my current one died, and I want to install OSX on it as a backup, so that if the MacMini has another hiccup (in the past the MacMini destroyed its own HDD during a harsh session of swap trashing, when I didn't knew XCode needed 6GB of RAM, and Apple will happily sell you dev machines with 4GB... this greatly delayed my project and made me get fined) I can use it in place of the MacMini.

 

I want to boot Windows7 (for games and windows dev), Linux (my main OS) and OSX.

 

I am not sure how to setup that, looking on google made me find mostly outdated information, I realized recently that is because google is biased toward pointing to some massive threads on this and some other forums, instead of new threads, for example it keeps throwing at me guides from 2009, because those threads have 6000+ replies for example.

 

So I want to know how I install this triple boot setup, from scratch, on UEFI mode, the machine has no OS in it, and my other machine available is this MacMini that has only OSX installed (so Windows tools would be a problem until I install Windows on the new machine).

 

Also I've seen the most popular bootloaders for OSX right now is Clover, Ozmosis, and crazy hybrid hacks (I saw a guy using some random EFI of his choice, that then would launch Grub to launch Linux, and launch Clover to launch OSX, thus having 3 bootloaders O.o and relying on "chaining" them).

 

Seemly the best choice, IF the mobo can do it, is Ozmosis, supporting most native OSX features, and booting the fastest, is this correct? Any guide on how I setup Ozmosis in a clean machine with a new BIOS file? (I think there is a Ozmosis bios mod for my mobo, but it is old, the manufacturer updated the BIOS a lot, and the new versions seemly are very awesome, with no reason to not use them).

 

If it is important, this is the stuff I bought, it didn't arrived yet:

 

ASRock Z97 Extreme4 (has bios socket, dual-bios switch, AMI bios)

Intel i5-4690K (how OSX handles overclocking, by the way?)

32gb DDR3-2400 1.65v ram (humm... does that work in OSX? or it barfs with ram modules faster than DDR3-1600?)

Radeon R9 380X (I know, I know... *nix in general is allergic to AMD :/ but nVidia recently pissed me off, this is my first AMD card)

3 HDDs

no SSD (yet)

no DVD-ROM (yet?)

Should be relatively simple to do since you have three drives and want three OSs on the machine. Simplest way connect one drive at a time to start  your installing install each OS on a drive for itself once completed use your boot selection menu to choose which drive thus OS to boot when turning on the machine. Better off using Clover to boot OSX as you never know what has been left out that may be important to the other OSs in that Ozmosis bios you would install on the machine. If wanting to share files between machines OSs then make sure you have at least one partition on a drive that is FAT32 which all OSs support natively or EXFAT which in linux at last requires a little more messing about to get it working with the fuse driver needed for it other two have native support. Overclocking no problem my 4690k runs at 4.2ghz@1.16v 24/7 under 100% load you just need to get it dialled in stable and Clover will use the settings in the bios when it boots same with the ram. Once everything is setup and running putting the OSX drive as first in the machine should allow Clover to see every OS in the machine when it does its scan giving you entries to choose from in its loader screen to simplify the boot process if not you can simply mount the EFI partition on each of the other OS drive and copy the *.efi boot files and their directories to the OSX drive EFI partition and to have them boot from it. Which in my experience may be the best idea as all these OSs seem to default to the first EFI partition seen in the machine for their boot loader installation/upgrading.

 

Installing you need to jump through a couple of hoops to get it done. With windows you need to create an EFI installer if using 7 then use your boot selection menu to boot the usb stick in EFI mode or it will not allow you to install on the GUID partitioned hard drive needed for an EFI install. In linux same idea (boot menu selection EFI) and you need to assign an EFI boot loader boot partition or it will not install Grub properly to it or at least that was the case with the Debian I used when doing this on EFI machine. OSX no need to install at all if you have external enclosure you can put its drive in for cloning and installing of the Clover onto to it to boot as it has been native EFI for a long time and knows what it is doing you just need to ensure you have it partitioned GUID not MBR and everything should go without a problem, just make sure to change the machine name in Sharing after booting to stop the duplicate machine name on the network that will happen. Think that is about all you need to know good luck on the new build.
