Here is what I did:

1. Install Kalyway Leopard disk - partitioning the drive into 2 partitions using the Disk Utility inside Leopard installer. Then install Leopard normally. You can have more partitions if needed but I only tested with 2.
2. Install Windows XP onto the second partition.
3. Windows XP setup will say that it will mark the partition active. Just accept it and continue. After its done, you will now only be able to boot into Windows as Windows took over (surprise surprise).
4. Boot the Kalyway disk again.. use -s for single user mode if you want. I used it.
5. Open Terminal
6. Type "fdisk -e /dev/rdisk0" ... replace rdisk0 to your correct drive.
7. Type the following in the fdisk prompt. Replace <#> with the partition number of the Leopard install. By typing p in the fdisk prompt, it'll tell you what number it is. e.g. 1
   • p
   • flag <#>
   • write
   • exit
8. Type reboot at the prompt
9. Done. Now Darwin bootloader can load either OS.

Example:
My setup: Single hard disk, 2 partitions: first being Leopard, second (small) being Windows. So my settings are /dev/rdisk0 and flag 1 in fdisk.

How to figure out your rdisk#:

• Don't boot into single user mode with -s boot option.
• Open Terminal
• Type "mount"
• It'll show your /Volume/Leopard (or whatever you named your leopard partition) mounted on /dev/disk#s##
• Your rdisk# is the disk#

Sweet!

Awesome guide, lonerdj... respect! I had read many posts filled with complex instructions and this is by far the easiest method I have seen.
Just a question. How did you set it ? GUID, EFI MBR... ? The more I read the more I get confused. I have installed lots of Windows, some Macs, but the mix is really hard. But your system seems to work so it would be nice to know that part of the process. Thanks!
I will rush into it anyway but ...

On my ECS system, its MBR EFI. On the Install, in the Customize screen I selected:
- Vanilla kernel
- Vanilla kernel, ACPI
- boot efi MBR

Thats after I partitioned the drive within the same Installer with Disk Utility. When I partition, I have it set as MBR. I haven't tried GUID with my board.

Thats it. Good luck.

It was what I need to know. Thank you very much; it was very helpful!!
Regards

What I did (the non-Terminal way):

• Load OSX (Kalyway 10.5.1 DVD) setup.
• Open Disk utility, Create new partition table (select disk at top of the list, not a partition), at least 2 partitions ofcourse (choose Master Boot Record [MBR]) under options, one extended journaled and one FAT32)
• Select the mac osx journaled formatted partition to install OSX to.
• Customize: check MBR bootloader, and drivers to suit your system (I didn't install vanilla but thats up to you).
• Intall.
• After install is complete setup will reboot your computer into your fresh osx.
• Continue entering the requested information (make sure you have either [ps/2 keyboard AND ps/2 mouse] OR [USB keyboard AND USB mouse] don't mix the two or your keyboard might not work).
• When finished, reboot into win xp install cd.
• Install XP to the FAT32 partition, setup will format the partition to ntfs.
• Windows will say it'll set the partition active, that's ok, continue install.
• Afterwards boot up into XP.
• Download Acronis disk director or something similar.
• Use acronis disk director to set your OSX partition active.

And voila! now you can use the darwin bootloader to boot either OS.

• Alternatively you can choose to install Acronis OS selector (start > program files > Acronis disk director suite > Install OS selector, to boot into either OS.

Enjoy the Appleness

Running smooth on Core 2 Duo T7200, Intel i945PM ICH7.

Now that the OS's seem te get along, let's keep our fingers crossed for the Windows/Mac fans to act likewise

I've already got Leopard installed on a single partition. How do I split that partition in two so I can install Vista ?

Cheers

@ Ol!ver

You can resize your MAC HFS partition using a tool like iPartition
and create a new partition for your vista install.
make sure it's a format vista setup will recognise. I think FAT32 will do (no experience with vista).

Hope this helps.

Cheers, I'll use NTFS I reckon.

Thanks for the link, knew there had to be some software somewhere !

Don't know if iPartition can create NTFS partitions, thats why I suggested FAT32.

Anyway, good luck

hi all, is it possible to use this method with win32 version of vista aswell?

Cheers
Gus

if you going to use vista the best and quickest method is to install leo then vista and use easybcd

what i did was install XP first, install OSX86 10.5.1 Kalyway's version with MBR option and no vanilla (i had some problems) and...that was all...it was dual boot.
when the boot loader timer counts down those 5 or so seconds to select the partition i want to boot from (default is osx) i just select the other partition....that has WinXP on it. works perfectly no problems so far.

@Love@1stMac

how did you partition your HDD?

I have a 320GB HDD and made the following partitions:

1. 15 GB for WinXP
2. 15 GB for MacOS X
3. 290GB for Other Stuff

I first installed XP, and want to install OS X later. So MBR works instead of GUID?

would that work, using your method? Or how did you do it?

thx,
Johnny_Bravo

Lonerdj,

I have two questions regarding kernels:
1) Is it possible to have dual boot, XP and Leopard with Vanilla Kernel?. I think it is interesting to get updates easily
2) Can I boot freely between Vanilla and TOH's kernels?. Which one is best?.

Thanks in advance!

Lonerdj and P.U.G,
I've followed your simple instructions and my install went very well. Now I have dual boot with Leopar and XP.
Thank you very much!

lonerdj, i followed your instructions but
it didnt work - i get the message
"error in booting operating sytem"
seems like theres no darwin bootloader anymore....

Right now I've got a 300 GB drive like so:

Partition 1 - Vista Beta (which I want to get rid of) NTFS 20GB C:
Partition 2 - XP NTFS 20GB D: Already installed, configured, etc
Partition 3 - Data NTFS 260GB E: Filled with games, apps, etc

I never use the Vista, so I wanted to put Kalyway on that. If I format the first partition as HFS journaled and install OSX on it, I should be able to boot into XP just fine through the Darwin bootloader? When I do boot XP, will my drive letters change? D: -> C:, E -> D:

Thanks

One easy way to avoid boot issues:

Use kalyway dvd to make two partitions.

Stop there and install Windows Xp first.

Then install kalyway Leopard last.

During the leopard install, it will set leopard back to the active partition and the darwin boot loader will automatically pick up the windows drive.

Enjoy dual booting without the use of bootcamp!

OK, I created three partitions (MBR): partition 1- 10 GB, FAT32; partition 2- 15 GB, FAT32; partition 3- 50 GB, HFS+. I installed OSX.5.1 first, booted, watched the video, and filled in the info (it worked multiple times after installing drivers and kexts)...

Then I installed XP. It booted. I added drivers for my mobo, etc. It booted fine multiple times.

Then I installed Vista, took a minute to authorize it over the phone - again. I added drivers for my mobo, etc. it booted fine several times as well.

Then, I booted up with the Kalyway DVD and typed -s at the prompt. It booted up into Shell. I followed the instructions here. everything seemed to go fine. Then on reboot, it hangs on the 1st darwin screen. Just freezes. How do I fix it? If I start with the DVD, it loads the bootloader and only osx partition shows up.

I have tried re-installing kalyway .5.1 with no change. I think it wrecked the first hd that I did it on (after like 4 tries) of trying different options. Has anyone had success with 3 partitions?

[update]
I found out by accident that if I type "rd=diskXsX", it boots into safe mode. I also found an error when booting from the osx partition from boot menu that says "HFS+ partition error". So, I guess I need to try to reformat the partition and re-install Leopard?.. or is there an easier way?

OSX86: Kalyway 10.5.1
MoBo: ASUS P5GC-MX/1333
VidCrd: MSI Nvidia 8500GT
IDE: DVD drive & 80GB HD

ThxInAdv

OK. So it must be a Vista issue. That's OK I guess. I'll always have Vista to do some neat tricks on my CD spindle. Lame.

So here is what I ended up doing:

1. Boot from Kalyway 10.5.1 DVD

2. Use DiskUtility to create partitions with MBR
-1st partition formatted HFS+
-2nd partition formatted FAT32

3. Exit DiskUtility and Reboot to XP install disc.
-(I formatted the empty partition to NTFS from here; but you probably don't have to)
-Install XP on the FAT32 (or NTFS) partition
-let it reboot and complete the install.
-go eat dinner
-Check and make sure the install was successful

4. Reboot to the Kalyway disc and install OSX86 (make sure you only check the "MBR" box under EFI)

Ta dah!! Thank you 2805

From the get go, I partitioned a disk to one Mac, on Windows with Seagate 7200.10 300G. My board is Gigabyte EP35-DS4.
I've installed XP in the second partition.
First I had to slipstream ICH9 AHCI driver to do the installation of XP, because the installer does not have it and I did not want to use floppy.
I installed it, and rebooted.
Now, the Intel AHCI bios hungs at scanning the Seagate disk.
If I don't unplug the disk, I cannot get to the bios setup.
I hooked up another SATA disk and it does work.
Also, if I disable the AHCI, the seagate disk boots into the XP too.
I know XP is a bad karma. But, I do not understand how on earth that installing XP does something bad to either the Intel AHCI bios, or the disk to make them to fail the SATA initialization negotiation in the boot up.
It's really frustrating as the disk seems fine as it boots into XP if I connect the disk to any of IDE designated SATA ports.

UPDATE:
I ended up "erase disk" with Seagate tool, the disk became "fresh new". I lost the installation but the disk is back in operation.
I suspect that XP installation did something to either MBR or partition table, and somehow it made AHCI bios hang.
Since then, I repartitioned the disk and put back the disk image of 10.5.2, and then put back the MBR with "fdisk -u" after booting up. It's working now, except XP installation is gone at the moment. I'm thining about next attacking plan.

UPDATE2:
You must not let the Windows installer to create a new partition from "free space". This will corrupt somewhere around the boot sector during XP installation that makes AHCI bios very unhappy. When installing Leo, create both X and DOS partition ahead of time.

You must not choose "convert from MS-DOS to NTFS" option during XP installation. Choose fresh NTFS partition. The boot loader will not be installed and you'll end up with the Windows partition that does not boot. You'll see "Disk Error" at the DOS boot loader and you'll scratch your head.

Hey guys,

So this is what I did:

Installed Kalyway 10.5.1 on MBR with two partitions (1 journaled 1 fat).
Updated to 10.5.2
Installed XP
Used acronis to set leopard partition active.
reboot: leopard boots fine but I am not getting a boot menu to choose xp.

What do i do?

Thaks for instrutions, finaly have both XP and 10.5.1 working great on the same HD.

Just started downloading Klayway a few minutes ago should be done in a couple hours... Is does this guide suggest that using easybcd won't work for the new Klayway or is it another suggestion.

I have a question:

XP kept having a hal.dll error when I did the install as stated. I did the following instead:

Booted XP Install disk. Partitioned HD in two. I formatted both partitions to NTFS.

I then installed XP on one of the partitions. Then, I popped in my Kalyway and did all that jazz. OS X boots fine when I flag that partition, but there is not an option for XP.

So, I tried flagging that partition using fdisk. That did not work either. The system would not boot to anything but CD then. No hint of a bootloader or anything.

So, I currently stand with a valid xp install, and a valid leopard install but I cannot get it to boot into Windows. For what its worth, I would use GParted but I have an IP35-e and there are a ton of issues with sata drives and the linux kernels on the live CDs. That is not a viable option for me unfortunately or it would solve this problem!

What options do I have?!?

Bump.

I have tried to the chain0 method, and OS X will show up in the boot loader, but when you select it the screen refreshes and displays the option to boot to both again.

I have seriously put in like 15 hours on this trying different tutorials. Nothing seems to work.

One problem I have is that I have an ip35-e and thus most linux kernels won't boot, including GParted.

Wow thanks for that how to t worked amazingly. I thought that it would in a smoking harddrive. And a crying person.

First Off The App Ipartition doesn't resize partitions on its own, unless its the Ipartition Live cd thats Boots from

DOS That can resize a partition without wiping it,

Good luck finding that, all i god was the program itself not the live cd it come with thats cuz i downloaded via the

Bay with pirates

you're better off Wiping it clean and partitioning it with Disk Utility
2 partitions chose the size u'reself

and you're wrong again no mac app including Disk Utility partitions in NTFS
They Only got FAT32
If you're able to Partition it to NTFS with Disk Utility then its a Modified File format and the windows CD won't recognize it

read the previous post before your and use that








I think the live CD would work
but what you're experiencing is simple Leopard has made its partion active to boot,
as windows would have done the same leaving you with onel 1 os to see and boot at a time,
u could use any1 of those acronics, hirens boots cd, choose partition tools and select an Fdisk program
and just make the partion you want the os from active!!!
you can make a boot loader with most of those programs with a menu for both os's thats the desired solution good luck

Agreed, lonerdj your multiboot how worked great for me can I suggest though instead of : flag <#>
simply : flag #
and then add where #equals your partition number, thats the only place I got hung up at

But thanks for your guide couldn't have gotten this far with the help of yoru post and this forum.

hi i successfully install ed kalyway 10.5.1 on drive D:
with gparted i made xp active partition.changed boot.ini
added
C:\chain0="Mac OS X86"

now it simply boots to xp
when i used acronis os selector its say HFS+ error
Pls help me
