[HowTo] XP + OSX 10.4.4-10.4.8 native dual boot

[cbmkgd]

The logical partitions begin at hda5 and on. If it's named hda3, it's primary.

 

If you created the extended just after the hda1 primary, it's named hda2; it's logical partitions will then be named hda5, hda6, etc.

You then created another primary, so it's called hda3. You could create a last primary, which would be named hda4.

 

Some people had problems creating an osx partition when it was after an extended partition on the disk, even if it was primary; read that some months ago, don't know what was the last word on that. I didn't take any chance, created a primary (physically) before the extended.

Whether this has to do with Acronis OSS not recognizing your osx partition, I don't know.

[dilnalomo]

ummmm, anyone know what's the cause of the " could not read partition map" error what comes up when you erasing the partition for osx during install?

[cbmkgd]

ummmm, anyone know what's the cause of the " could not read partition map" error what comes up when you erasing the partition for osx during install?

Possibilities (not certainties):

• Installing on a primary but non-active partition
  
• Using DiskUtilities in vmware at same time there is a diskpart or PartitionMagic open
  
• Installing on a logical partition
  
• Installing on sata drive with nforce4 board (has this been solved?)
  

I have not tried to reproduce any of these; read about them in this thread:

http://forum.osx86project.org/index.php?sh...ic=11314&st=100

beginning at post #100.

 

One would need context of those who got this error to see what's in common: board/chipset, which type and state of partition, software used, what kind of hd, etc...

[dilnalomo]

in order for my guide to work, the osx partition has to be a logical non-primary partition. for my countless osx installs, i got that error 3 times at least, but other times i was fine.

 

does the location of the osx partition on the HD has anything to do with this error? cause i read in other guides that it's the best to put the partition at the end of the HD.

• A few months ago when I came here (and that other place that got shut down) some people reported problems if the install partition was made after the extended partition. Apart from that, never heard any other kind of problems as to where physically the primary partition should be located on the first drive. But I personally never saw a guide stating the end of the disk was a better place (but then I never read all the guides around!).
  
• I did notice a few guides suggesting an install on the very first partition of the first drive, where OSX expects to be. Not convenient if you have to displace the Windows partition (which can cause problems for Win2k-XP).
  

in order for my guide to work, the osx partition has to be a logical non-primary partition. for my countless osx installs, i got that error 3 times at least, but other times i was fine.

• Unless I'm very lucky, the only part of your guide I needed was the suggestion to use AOSS, since I had already installed OSX on a primary active partition (before the extended partition). From my POV these are the main points of your method: installation of AOSSelector; creation of a primary (FAT) partition of type 0xAF* before the extended partition; that partition to be made active; installation of OSX after HFS+ reformating by DiskUtility. (although i also made the windows partition hidden before the install)
  Heck, even installing AOSS after OSX worked for me. But of course that's only my experience. In your experience, did you ever get an error if you tried installing OSX in an active primary partition first and letting AOSS recognize it? Did you get to the logical partition step after failures with installations directly to a primary?
  Just for the heck of it, I'll just do it again from scratch (backing up partition with... Acronis TrueImage!) and installing AOSS from its RecoveryDisk (which I emphatically suggest people create before installing AOSS). I want to be absolutely sure. I'll report back... wish me luck!
  

As for the "could not read partition map" error, we'd have to collect experiences to pinpoint the origin. Check the thread I linked in my previous post where some people dealt with it and had some theories.

 

/ *edited june7th after testing. Has to be 0xAF, not FAT.

[cbmkgd]

Well, I've been formating, reinstalling, etc, and here's the results.

 

Firstly I want to mention I had 7GB of unallocated space to create another partition, so I chose that to install a second OSX install partition. I used Acronis Disk Director (A.D.D.) and then Acronis OS Selector (AOSS) from their bootable disk.

• I created a Primary Active partition of type FAT32 with A.D.D., and then booted with the OSX install disk; upon an attempt to erase (and format to hfs+) that partition the Disk Utility gave me the dreaded "could not read partition map" error.
  Bummer.
  I retried many times, and the error message was still there. No "hit and miss", only "miss".
  
• Knowing that I had succeeded before on installing osx on an active primary partition, when i had partitioned with diskpart and setting "id=af", I retried but this time in A.D.D., but rather than create a FAT32 partition I right-clicked the partition, chose Advanced->Change Type, and set the type to 0xAF (ShagOS swap).
  
• I then rebooted on the OSX install disk, and now its Disk Utility accepted to erase/format the partition. Yeah!
  
• I completed the install of OSX, checked that it was ok, then rebooted on the Acronis CD and with A.D.D. I put the Windows partition active again.
  
• Upon rebooting on the Acronis CD again, I then installed AOSS, and on rebooting recognized both OSXs, Windows (and my two Linuxes).
  

Side notes:

• Before installing OSX, I made the Windows partition invisible (I like it that way). Made visible again after the install.
  
• In fact, AOSS did recognize both OSXs, but my original one got a HFS+ error. A.D.D. showed me it's partition type had changed to 0xBF. I changed it back to 0xAF, and now both OSXs are accessible to AOSS.
  
• I decided this time to install the Acronis OS Selector in a separate FAT32/non system partition, rather than my Windows2K NTFS one; maybe it won't be buggy this time.
  

So why did the DiskUtility give me a "could not read partition map" error message when trying to erase a FAT32 active primary partition, while it doesn't when some erase a logical FAT32 partition? I don't know. But at least I could reproduce the message. And if I don't know the source of the problem, at least I know a solution:

the importance of setting the type as 0xAF when installing directly on a primary active partition.

It works, and although you have to find the right way to edit the type in A.D.D., it takes less time than a transfer from one partition to another. Also, maybe setting the logical partition to 0xAF also can avoid the occasional error you've been encountering in your guide.

So when we've seen guides telling us to set type to 0xaf, now we know (i think) how it can avoid us trouble.

 

I'll be editing my posts in this thread to reflect these observations.

You can set the Windows partition default in Darwin bootloader. Go to MacOSX -> System Preferences -> Startup Disk and you will see the both active partitions (MacOSX and Windows - it depend how you named these partitions). Select one of them and you can set default in Darwin bootlaoder. I used only the Darwin bootloader and I'm so satisfied.

[XanthraX]

Thanks for this guide. I have installed the both OSes, without OS selector.

1 - Windows XP, I installed Acronis Disk Director 9, but I didn't activate Acronis OS Selector.

2 - I created a new primary partition Fat32, in the same disk with windows partition (Acronis permitted me to have 2 primary partitions on the same disk)

3 - I set the new primary partition active with Acronis Disk Director (Attention! - Windows XP requires active partition only in its installation steps, than is not necessarry its partition to be active)

4 - I installed OSX86 (10.4.5 MyZar)

5 - after reboot, I edited com.apple.Boot.plist - related to delete the

[tab]<key>kernel flags</key>

[tab]<string>-v</string>

and I let the boot delay to 10 seconds. I get rid to verbose mode boot

6 - My Darwin bootloader sees the Windows partition, but I let MacOSX to be the default OS, cuz I booted into Windows rarely (in my previous post I wrote how is possible to set the Windows partition to be default)

 

Warning!!! I followed these steps sometimes in the last time, cuz I did some erroneous things and some time ago I lost my both partitions on the harddrive. Sometimes after OSX installation, Windows refuzes to boot. No problem, I reinstalled it with repair option (without formatting) and it works.

Hope this helps you

[XanthraX]

i have no idea how to use grub, but i am sure it's possible to use partition magic to make your partition primary.

 

Now I'm away from my computer. I editi this on other. But afayk, Partition Magic don't let you have more than 1 (ONE) primary partition on the same disk. That was my reason to chose Acronis Disk Director to partitioning. Hope no wrong.

[cbmkgd]

There can be up to 4 primary partitions on a drive, the standard way; it's not Acronis' doing (there are some tools, eg BootIt NG, that can try to do even more, but i never tried that).

 

So you were able to create a primary FAT32 partition and install osx on it?

So now I still have to figure out why Disk Utility didn't want to erase the ones I was creating, giving me the "could not read partition map" error...

Oh well...

[XanthraX]

...Now I have a question. Is there a way to make OS X mount and extended NTFS volume?? it mounts the Windows partition that's a primary one but the other partition with all my files isn't mounted. What could happen if I convert it to primary and have 3 primary partitions on just one HD?

 

Thanks for your guide!!! it was very useful =D

 

I read now this topic. WARNING!!! But if is not too late, BACKUP ALL DATA FROM THIS PARTITION, you will shortly or not to lose this partition. All my partitions (primary, logical) will be normally mounted. When my first installed OSX (10.4.1) didn't see and one of the partitions (logical, on other HD then OSX was installed), after some days, I lost the partiion, without made nothing special.

 

I strongly recommend to backup all important data on this partition, than delete and repartition it.

 

...o you were able to create a primary FAT32 partition and install osx on it?

 

Yes, but on Disk Utility you must erase this parttiion using HFS+ extended (optional Journaled) format

[cbmkgd]

Yes, but on Disk Utility you must erase this parttiion using HFS+ extended (optional Journaled) format

This what I tried, more than one time, all I got was the infamous error message: "could not read partition map". Tried to verify/repair disk, which said nothing was wrong. Mounting didn't work either. It's only when I changed it's partition type to 0xAF that it accepted to work with it.

[Windosx]

I have set my compter to boot from a cd, the install DVD has worked before for my computer, but it takes forever to boot the install DVD. The DVD sometimes takes 10 min. 30 or even 2 hrs.

Any suggestions? My BIOS is properly configured to boot from a dvd and has been configured for max compatibility in other settings.

 

Setup:

Intel P4 HT, SSE3

80 GB HDD

20 B Partition for OS X

JLMC 16x DVD drive, w/ latest firmware (in theory, can boot more easily from cds/dvds)

MAC OSX UNIVERSAL ISO DVD Intel and AMD

[silencethevoice]

Well.. My installation went fine, I followed every step of this guide (set my disk to primary / active).. But my problem in the middle of loading osx86, my machine reboots. I can get it to boot up, fly through all the verbose messages, but at the very end, my system restarts.. Hardware issue? I am running a P4 3.0 Ghz HyperThread Cpu with a D875PBZ intel mainboard, and a Winfast Graphics Card... I am running a single IDE 40 gb drive, split into to partitions (1 for XP, 1 for X) xp works fine.. Could it be the winfast? I have tried installing with and without the various patches for SSE3, 10.4.5 update/10.4.6 update. Is there a patch I'm missing? Anyone have any suggestions, I've searched my ass off, to no avail...

 

Thanks in advance,

 

Ryan

[punkrockguy]

I followed this tutorial and installed OSX on my dell Inspiron E1505. It is the one with the 1.66 core duo. I have the dual core shut off. OSX installed just fine on it. It installed and booted and I did the account set up. When it got to the desktop I restarted so I could go on with the tutorial and set up the dual boot thing. When I restarted, all it would do is show an error right away. [XLDR] ATA error. Anone know what this means? I searched but couldn't find an answer. Any help would be appreciated. Thanks!

EDIT: Ok, this is wierd! If I leave the osx86 disc in the dvd drive, it will boot OSX! ANyone have any ideas what is going on? Thanks!

[dcm]

yay, got it working ! thanks for this great guide

 

 

My setup is:

 

Partition 1: Win Vista

Partition 2: Grub Boot partition

Partition 3: Apple OSX!

Partition 4: Apps/Storage (NTFS) logical

 

grub which loads osx darwin bootloader after 1 second (just to keep grub active )

darwin bootlaoder then loads windows after 2 seconds unless interupted to load mac

 

 

Is there a way to delete the darwin bootloader? Do you justdelete the darwin.boot file found when running OSX? (just wondering)

 

 

 

 

 

1. Name of the ISO:

 

HOTISO

 

 

2. PC specs:

 

AMD Athlon 64, SSE2,SSE3, 3500+

Wireless Logitech Keyboard+Mouse (MX3000 i think..)

 

3. Anything else you want to share.

 

BEWARE of bad iso.. i first tried

OSx86 [MaC.OsX.10.4.5.Universal.Install.DVD(INTEL_AMD_SSE3_SSE2)]

 

and it didn't work!, only showed command line.. I think it's INTEL only.

 

 

 

Also, I had problems understanding that i had to use OS selecter to partition it, i think you should say that you HAVE to use it in order for the mbr to recognise the mac partition properly (ie convert from logical to primary) this is was what made mine work.

 

Another thing that should be made clearer is that you MUST format the OSX partition with FAT32 before installing OSX, otherwise you may get HFS error.

 

Also once you have it working through OS selector, GRUB should be able to load it, and also you can set OSX partition as active and that will work too (AFTER using the logical to primary trick) so this means you can disable the OS selector when your finished. And the timeouts for Darwin can be changed

 

IF you don't use that logical to primary trick you will get other errors.

[mbw163]

Sorry for my newb question, but I cant get the installation of the new partition to work. How do I go about moving the partitions around on the hard drive? If I put the partition at the end it comes with an error when it tries to create the partition.

 

Thanks

 

There might be more questions to come but for now i'm fine.

[gentoohippy]

Hey guys

 

I haven't read all the posts, so correct me if this issue has been solved, but when I boot to the install, I get the apple with the spinning wheel at the bottom, but then it seems to freeze, and a circle with a line through it (like in the no smoking signs) pops up. wtf? I did -v, and it seems to be something with the vid card? but I treid it with 2 different nvidia's and it still doens't work. Any ideas? is it a hardware issue?

[dcm]

maybe a hardware prob download http://www.cpuid.com/cpuz.php and check your cpu and paste screens or a log

 

Also reinstalling with only the drivers you need may work , Nvidia thing mesed me up so i had to reinstall...

 

 

"Sorry for my newb question, but I cant get the installation of the new partition to work. How do I go about moving the partitions around on the hard drive? If I put the partition at the end it comes with an error when it tries to create the partition. "

 

You need a Partition Tool (Partition Magic is good for moving your disk stuff around.. eg it moved my C,D and E drive to the end of my HDD and allowed for a new partition at the front)

BEWARE though, partition magic(and ohers) can mess up your stuff bad if you don't know what ur doing. You should backup your most important files.

(You can recover files so if your drive messes up don't worry too much, and don't reinstall anything besides a recovery tool )

I recommend making your OSX partition between your windows and any other partitions EG: WINXP/OSX/OTHER/OTHER

 

You also MUST defragment your hard drives before you move partitions around, and it will take a very long time to move your data (it took me 3 hours at least) so once you reboot after setting up the partitions don't worry about a very long loading time, leave the compueter until it reboots.. or else it will mess it up and need a recovery app.

 

The new partition you create MUST be FAT32

 

After making the new partiion a FAT32 partition, Install OSX onto it following this guide After installing/rebooting, load up winxp to activate Acronis OS selector and then reboot.

 

Since Acronis OS selector is activated, you should now boot into the OS selector, in OS selector select Disk Director and then click on the logical OSX (it had changed from FAT32 to OSX filesytem since mac installation) and click convert to change it to primary partition instead of a logical.

 

You should be able to load OSX up by exiting Disk Director and clicking OSX/Unkown operating system in the OS selector menu.

 

 

 

Also, I think it should be made clearer that you should only install the Drivers that you need during the MAC Install "Customise", you will interfer with devices if you choose too many of the same type, eg: selecting all sound drivers. I selected all drivers on my first install and it didn't have sound, and i got lots of poop ups at the start, then i reinstalled with juust the 10.4.6 upgrade and AMD patches and it fixed my problems and I had sound without any extra drivers!

 

It's ok to select all AMD patches if you have AMD sse2,AMD sse3 though

[gentoohippy]

Thats a shot of cpu-z. I also thought it could be that I have one SATA hdd and I don't have a USB keyboard. But I'm planning to install it on a 9 gb hard drive i found, ATA, so serial ATA. I booted the DVD in verbose mode, and it froze on this.

Also, I have Gentoo Linux on my SATA disk, and use grub to dual boot Linux and Windows. I can use grub to boot OS x86 right? I saw an article around here on that, but i can't find it again Something like...

 

title Mac OS

root (hd1,0)

makeactive

boot

 

^ am I even close

[dcm]

Your chip seems fine, it has sse3/sse2 and it's intel so i suspect it works I'm AMD so i'm not 100% sure on that though.

 

you may need a USB keyboard..

 

but that problem happens alot with SATA drives (didn't realise you had two ! (thought the second was IDE)

 

it's most likely that, you need a IDE drive! (most likely)

 

here is a page i found

http://allansiew.blogspot.com/2006/05/osx8...g-for-root.html

 

 

as for grub, i use grub..kind of... as a backup..

 

 

I have one partition which is my grub partition, then win vista, then mac

 

my grub is loaded into mbr and loads up first (when acronis is diactivated) i have it set so it only loads for one second!, in the grub conf i have macOSX as default and then windows.

 

since mac is default it will load straight to the mac bootloader on the mac bootloader i have winxp as my default and i have 3 seconds to choose mac.

 

so since you have gentoo.. i'd recommend you set up grub like:

 

OSX (default loads after 5 seconds)

GENTOO

WINDOWS (incase OSX doesn't list windows)

 

in your grub.conf make a new title called OSX above your other selections.

 

title APPLE OSX

root (hd0,0)

chainloader +1

 

Make sure to replace root (hd0,0) with whatever you think should go there to bring up your OSX partition

 

yea it maybe (hd1,0) like u said since you have 2 harddrives.

[gentoohippy]

Yea, I've got one SATA and one IDE. Should I set the IDE to primary and try it again?

 

How about a little converter to change the keyboard into USB? (those are cool)

[dcm]

Yea you must install on an IDE drive, maybe even take out the stat..if you're having problems.

 

I have not heard of a converter that makes something usb , it's usually the other way round, lol i'd try the IDE thing first :pirate2:.

 

 

Im not sure about installing on two seperate drives.

If the IDE drive is 9 gigs and has no other Operating Sysyems on it, I think you could install OSX on it without any much trouble. Set it to active and install OSX and see what happens.

 

But if the IDE drive is the large one, then you need to partition off a section for OSX . Make the OSX partition a LOGICAL partition and not a PRIMARY. When OSX is installed on the partition convert it to a primary partition.

 

I don't know if sata works so that's if you can't use sata .

[Coop]

Ok, I've been working away at this for about a week or so now and can't get it to work.... It does work in VMWare Installs fine and everything without doing anything special, but when i try to install it on my system i get the infamous hdd error.. which is kinda solved by using the rd=disk0s* -v route but only gets slightly further (to a line like this : kernel version: darwin kernel version 8.4.1: Tue Jan 3 18:23:53 PST2006; Rootixnu-792.7.90.obj~1/release_I386) than stops before entering the setup.

 

what am i doing wrong or what suggestions could be made?

 

any help would be greatful

 

Thanks!

[mikeh]

Well, this is my first post here.

 

I am using the "Mac osx86 10.4.4 Install DVD" iso, which I have burned to a DVD. It launches correctly, but when it comes to the Disk Utility, it doesn't see my partitions, just the C: drive @ 128 gig.

 

The other drives are D&E (disc drives) and F (I want to install OSX here) and G (25gig data partition)

 

I created the fat32 logical partition with acronis, committed the changes etc.

 

I can see the partitions in both OS Selector and in My Computer. What should I do?

 

edit: its an ide drive.
