Interesting, I think that by the time you're trying out OSX86 on your computer you will probably be aware of and assuming the risk, that its most likely to cause issues and errors that require you to reinstall (in all likelihood a few reinstalls
) if attempting a dual/multiboot.
That article would only apply if you're installing OSX on a separate drive and those steps would probably be required BEFORE attempting OSX installation which means you would be doing the install OSX on a new/separate drive seeing that you have to use GUID partitioning for OSX on intel computers and any previous windows installation would likely have been on an MBR partition... stating the obvious here, I know.....
However, if you're following the
tonymacx86 iBoot guide (its like the best guide ever!
) for dual booting off the same HDD, then you should not have any of the issues which the article aims to resolve
assuming you had set the bios setting correctly to begin with before attempting to install vista or win7.
IMO I think that if you want to make it easy going then follow the iBoot guide and dont rush it, undertake each step carefully as instructed. Try dual/multi booting later and off separate HDD's, also make sense if your OSX is on a seperate drive on its own, in case some does go wrong (because it will) you can still access the internet (by disconnecting the OSX drive and using only the windows/linux drive) for trouble shooting if you have only one computer. two cents worth of unsolicited thoughts....
If dual/multibooting off several drives then just follow the guide step by step (patience is a virtue in these things) and install windows first, and OSX last e.g. if installing linux as well, install windows first (easiest option), login to windows and make sure its ok, then do the linux installation, then lastly OSX and multibeast. With linux, install grub on the root linux partition (if in MBR).
I have no idea on other linux bootloaders as I only use Ubuntu... I tried it with OSX in my install but it didnt work but I was happy to note that IF it could work, without serious scripting, you can choose between 32 and 64bit kernel at the grub menu, I'll look into that later and see if its possible to use a custom grub entry to get it going in either option... food for thought...
Lets just say I know this from experience
... I've had my OSX86 for about two weeks and I'm loving it!!! I can now install it with my eyes closed on my desktop... but I'm also careful, I have a time machine back up, and a whole separate drive which works perfectly unplugged and unused as a back up! Just in case....
The moral of this post is if you already have windows installed, and want to try out OSX86 you have to use a separate drive for OSX and fix the ACHI issue first, otherwise you should not encounter this issue.
