the simple way that worked for me: (not know if it's the easiest though)

XP already installed, made free space after c: for OSX, after the install of 10.4.3 1111, went to Pref - Startup and select OSX, edited /Library/Preferences/SystemConfiguration/com.apple.Boot.plist

and added these lines

way to do it:

1. open teminal and type:

sudo -s

nano /Library/Preferences/SystemConfiguration/com.apple.Boot.plist

2.add

<key>Quiet Boot</key>

<string>No</string>

<key>Timeout</key>

<string>10</string>

 

quit and restart

normaly you shoul have 10s to press F8 and then you got your Darwin bootloader :)

Even with no timeout set, I can hit F8 to get to the Darwin boot prompt.

I read that chain0 locates the HFS+ partition and proceeds to boot from it. I'm going to have XP on one disk, Linux on another and OSx86 on a third.. will chain0 search for HFS across multiple disks?

Sure I have chain0 file in my WinXP disk (that it is a RAID/SATA setup) and the Mac OS X Disk in the PATA channel, and it loads perfectly.

My guide to multibooting OSX and XP

 

Step 1) Formatted Laptop

Step 2) Put OSX Cd in drive

Step 3) As soon as the disc boots up, go into the disk manager and create two partitions (OSX and XP)

Step 4) Formatted the first partiton for the Mac OS

Step 5) formatted the second parition for XP

Step 6) Install OS X onto first parition

Step 7) Install XP onto second parition

Step 8) Boot off of the OSX install disk

Step 9) As soon as the disc boots up and you're in the installer, go into the tools and change the startup disc back to the Mac parition

Step 10) Reboot

Step 11) When you get to the Mac screen that says "Press F8 for options", press F8. You should see both OS's there.

Step 12) Choose the OS you want to boot

Step 13) Enjoy

 

 

Please note, in step 11, if you don't press anything the computer will automatically boot into OSX after several seconds (you'll see a timer count down)

I seem to have the same issue as these folks...maybe...

 

I have a fully working OSx86 with the Darwin boot loader that of course loads OSx86 by default...because that is in the first partition and XP is in the second.

 

I have tried changing the boot disk in OSx preferences...but it simply shows "invalid boot disk" upon the boot...and then I also lose the Darwin loader...I have to fdisk reset primary partion to boot etc.

 

Anywho...I would simply like the default boot to be XP...and if I hit a button THEN I could select OSx...

 

Other than using Acronis...is their a way to tell Darwin to do it?

chain0 doesn't work for me.

I have three partitions. The first and last is formatted to ntfs and the middle is for OS X 10.4.3 8f1099 (maxxuss-patched).

1. OSX installed and run fine on disk0s2

2. I copied chain0 to C:\ and edited boot.ini as described earlier.

3. Next time I rebooted I see "MacOSx86" in XP boot menu. After selecting it screen clears nothing happen for about 2 seconds then XP boot menu returns. It means chain0 cannot recognize or find HFS+ partition. No error message but silently fail and return to XP boot.

 

I tried fixing it by doing Startup Disk stuff: same result.

 

I've got exactly the same problem. I've copied the chain0 file to my c-drive. Adjusted the boot.ini and it just returns to the XP bootscreen.

Virii, do these steps really work? My understanding was that a successful install of XP requires that it be run from the default boot partition (the first partition?).

I always installed OSX86 first like you do on a DTK, that works (but OSX86 and M$ have a primary partition):

Here's my configuration:

 

80 Gb IDE - Win XP. NTFS

300 GB NTFS - some files

300 GB NTFS - some more files

 

Works perfectly. No macos, as u see...

Next:

80 Gb SATA, macos 10.4.3 with wesley patch... Well, it works...

Next "chain0" and etc... Dual Boot.... YES, it works.

 

And finally...

Under macos format two 300 HD to HFS... Reboot to windows, use macdrive... Yeah, it works... Reboot again... Choose macos in boot loader... And that's it... No luck... Some file can't be found... Sure, it can't cause if i press the F8 key, it shows me, that it gonna to start up from my 300 HD, which is not system... ;-) After simply unplug 80 gb with XP and reboot without boot loader... I'm in - in MacOS again...

 

 

ANy suggestions to make that chain0 work again? ;-)

I loaded OS on a IBM T40 and heres how I did mine:

 

1 Booted to OSX and created 2 partitions (40GB HD)

1 DOS and 1 MAC

2 Booted to Windows XP and installed (NTFS) on DOS partition

3 Booted to OSX and installed on 2nd partition

4 Boot screen displays:

hd0(1) Windows NTFS

hd0(2) Mac OSX

 

Works perfect!!! :graduated:

First I had dual boot with the chain0 file.

 

Recently I upgraded to 10.4.3 and now that doesn't work anymore.

 

I know there are all sorts of solutions, but I think the chain0 was the most simple and elegant. Is it possible there will ben a new version of chain0 which will work with 10.4.3?

Okay, after solving how to actually edit the BOOT.INI file, I will teach you step-by-step!

 

- Go into your OSX drive (you might need MacDrive to see the OSX contents)

- Go to /usr/standalone/i386/ and copy the "chain0" file

- Paste it (chain0) into your Windows root drive (C:\), so it should be like this "C:\chain0"

- Click Start > Run > type in sysdm.cpl

- Click the Advanced tab, then under Startup and Recovery, click Settings

- Under System Startup click Edit (the file should open in notepad for editing)

- Under "multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="YOUR WINDOWS OS HERE" /fastdetect", insert the following: C:\chain0="Mac OS X"

- In notepad, go to File > Save

- Restart and you will see success! It will give you a choice of Windows or Mac OS X

 

 

Hope you enjoy!

Discaimer >>> I have not tried this yet.

 

 

Here is the old style of dual booting for people to consider that are having problems getting anything else to work, the only problem is I don't know how you could get to work on sata but maybe some people that know all about them could,

 

 

You take a DPDT toggle switch (the small flat lever one from GC Elect pn#35-057 looks nice costs about 8 bucks but others are much cheaper)

 

and get a bag full of colored wires (E-Z-Hook pn#9110-12-5R and you won't need solder or an iron they have little pin socket connectors on them already) edit: Well bummer maybe you do need a solder iron looks like the pins on the switch are too big, but the other end should fit the jumper pins easily.

 

 

take one of the bay covers and drill a hole in the center to mount the switch, cover it with masking tape first so it doesn get all scratched up.

 

 

then you use an ohm meter or a DPDT diagram to find out which contacts are connecting when the switch is in the two different positions and connect the switch to two different hard drives in a way that replaces the jumpers on the hard drive, but connects one or the other when you flip the switch.

 

then use the switch to select a drive before you turn the computer on.

 

I know that is kinda old fashioned and rustic but probably works, they used to sell an item that did this but instead of a toggle switch you used a round key and it had it had a middle position where no hard drive was connected as a security feature.

 

Somewhere on the web is instructions with pictures sorry I forgot to bookmark it and it was a long time ago that I saw so don't remember the name of the site.

hi all,

 

I've just tried last week to install mac osx 10.4.3 8f111 on my win98/xp dual boot.

My system is a p4 northwood(sse2) on an abit 845se,nvida 4200Ti, creative audigy.

at the beginning i tried to install mac os x on a primary partition after the win98 primary partition but I had winxp on an extended partition, it loaded but the boot was really problematic, then I converted the xp partition in primary and I put the af partion after winxp always as primary and then I could get the darwin boot loader running well. It also gave the boot choise to win98/winxp boot menu.

Then I tried to set up the win98 primary partition on active and I've copied the chain0 from the mac partition and changed the boot.ini adding c:\chain0="mac os x" as explained above the topic.

At the beginning if i chose macosx after less the one second I got the win boot menu again.

Then I have read on the above topic that someone could load the darwin boot loader if after the win boot menu after having chosen the macosx hit the f8 key.

i can confirm that in this way mac os it will load!

the only problem is the audio that is well known not working with audigy...may be someone in the future will be able to release some drivers!

 

thank you very much to all of you guy without you I couldn't get it working.

by the way what about the 10.4.4 is already possible to install on x86 pc?

bye marco

Hi Guys..

 

This is my first post.. hello all.. :(

 

Ive been having a few problems with setting up dual boot on my laptop.. lets start with current setup

 

Ive got an ibm t40 with 10GB C: (primary) and 10GB D: (Logical).

 

D: was 20GB so i shrank that to 10GB with pm and shrank the extended that it was in to leave me 10GB free space at the end..

 

I then booted dsl to create the af partition..

 

i then ran the installer.. (im having problems with IO errors here but this may be my dvd drive, as it take anything from 30 - 45 mins to get to install screens) and repaired my newly created partition (is this normal?)

 

Once i had repaired and mounted the partition i went to install it.. but it told me OS X would not be able to start from this location.. and so i hit a brickwall..

 

Im assuming that its something to do with the af primary partition being located after an extended partition.. im in the process of trying to prove this by moving the extended partiton to the end of the disk.. and creating a new af one straight after C:.. but im doing a backup if D: first..

 

So while im waiting i thought i would share my experiances with you all and see if anybody knows of any other reason why it wont let me install that i dont know of yet.. and why does it take so bloody long to get to the install screen.. (ive been through that process twice now and with it taking that long i want to get it right this time :happymac: )

 

 

Thanks Townfool

Why do you people want to dual boot anyway? All I do is hit F8 when my computer finishes it's POST, (to get to my "select boot device" option. (Yes I know that not everybodys mobo has this feature so don't flame me!))and then pick the drive I want to boot from eg. my Windows drive, or my OSx86 drive. No messy dual boot promblems at all! Just my two cents......
