dual boot from seperate HDs

[darkforests]

Ok I have leopard installed on one of my 250 gig sata hard drives with darwin booting it up fine. I want to install vista to my other 250 gig sata hard drive. I want to know the easy way to dual boot. I have already tried this once, installed leopard to one HD and then vista to the other HD. Then vista would boot instead of leopard, so I downloaded that EasyBCD or whatever it was called and added an entry for generic x86 i think it was and then when ever I would select the OS X enter from the boot menu, it just gave me a black screen. In the EasyBCD I never found a spot to select a location for leopard (my other HD) so I never thought it would know it was there anyway. Can anybody help me out here?

I've managed to dual boot XP and Leopard.. using 2 separate HDD, by using the MOtherboard Bios boot selector..

 

Pleseing F12 on certian ASUS and gigabyte baords.. alows you to choose your boot device..

 

I've also managed to get parallels installed on the Leopard drive.. to boot the XP drive.. within leopard.. works strangely well..

 

Use parallels for causal XP use .. or dual boot back to XP if you need the videocard - speed...

 

If only shutdown on leopard would work properly...

I have the same problem, more or less (I'm using XP instead of Vista).

 

OSX on drive 1

XP on drive 2

Time Machine on drive 3

 

All physically separated drives, so I can't use the Darwin bootloader. I don't like to press F12 at startup if I want to boot XP, but I don't want to use chain0 either, since that boots XP by default. I want OSX to be the default OS in a bootloader, giving me a timeout of 10 seconds to chicken out and choose XP . The Darwin bootloader only boots from the same disk, multiple partitions, and I have the luxury of three seperate disks .

I don't want to install Linux just for Grub though... any other options?

ive got the same problem.

how can i dual boot with two separte hds :/?

[bradybear]

Well, after banging my head for a while, I found a file called tboot (attached) and I'm now dual booting Leo and xp on seperate drives. I just copied tboot to the windows boot partition and in xp's boot.ini added the line "C:\TBOOT="OSX LEO"". All is working.

tboot.zip

Best way for multi Disk boot is:

 

I you already have XP: XP bootloader with Chain0 method

 

I you already have Vista: Vista bootloader with EasyBCD with mac.mbr method

 

I you already have Linux: GRUB bootloader with chainloader or PC-Efi_V8 methods

Hi,

 

I tried tboot but when I select OS X LEO is says it can´t find a HFS partition. What am I doing wrong?

 

I have one 200gb sata with XP on sata1 port and a 250gb sata with Leopard on sata3.

Since that doesn´t work I switched the sata ports to boot directly to Leo.

 

Any help?

 

Thanks,

E.

what's the best way to dual boot xp and os x on separate hard drives when os x is installed using GUID? chain0 doesn't work any more.

Bradybear, you should give more complete instructions on editing "BOOT.ini" please.

 

There are some important things in there, and not editing it properly could cause your system not to boot/general frustration.

 

Okay, while typing this I decided to create an example, I overcame my laziness.

 

[boot loader]

timeout=30

default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS

 

[operating systems]

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /NoExecute=OptIn

C:\TBOOT="OSX LEO"

 

This is what it would look like in my case, but yours may differ, depending on how your disks are setup. the key is getting the RDISK(#) right and the PARTITION(#) right. This could differ system to system, which disk is Master which is Slave, etc. But simply adding the line C:\TBOOT="OSX LEO" at the end should work, unfortuanately after testing it out, I get "No HFS partition was found" I think maybe Windows did something to the other HDD because I can't boot into LEO now even if I boot straight from the other "LEO disk".

I think that this is right, i'm going to test and let you guys know. -Nuck

Hi all guys!

Well I'm trying to install both xp 32 and os x leo on two HDs, I already have a functional xp 32 disk, and tried last night install os x on another disk without success. I'll try today again, but a few questions are unsolved... First one, would I need to disconnect my XP disk before install os X? And when installing Kalyway can I choose Guid or mbr without problems right? Because I'm booting they in separate disks. And If I choose mbr only xp or vista 64 support Efi but with separate disks this thing didn't matter, isn't it?

When installing Kaly, I made sure Kaly disk was plugged into SATA1 and XP disk was any other SATA, boot from DVD was enable in Bios, then installed, rebooted into OSX fine.

 

Now I'm trying to make dual boot work, as of right now, the TBOOT method is giving me "HFS+ partition error", and I can dual boot by choosing the "XP disk" as boot device in Bios.

 

That's lame, but for now it works, I have a Asus P5W DH deluxe board, and I also need to get networking going on it. For some reason, as the OSX starts up, the NIC's on the board just go away.

I used EasyBCD NeoGrub, but also WinGrub and Grub for DOS works.

 

just put in the menu.list the boot_v8

 

somenthing like this:

 

title Leopard

kernel (hd0,0)/grub/boot_v8

 

of course "(hd0,0)/grub/" may vary, depending which disk are you booting from and in which directory you have the boot_v8

Hmmm after installing my os X I will try this one with EasyBCD, but this one works well with XP? Because I saw many tests only under XP.

Thanks

Gad, I hate to get so difficult, but could you be a little more specific about how to do this MacGirl, I could not get EasyBCD working under XP, its giving me all kinds of errors about Not having VISTA, also, had to install .NET 2, I do have WinGrub downloaded but do not know how to use it, especially whenever I have two separate hard drives.

*UPDATE*

 

I tried the Chain0 method, by copying Chain0 from a Darwinx86 image, as described in the osx86 wiki, however, I still get the HFS+ Partition Error.

[macgirl]

If you want to make EasyBCD to work with XP I wrote a post in this thread: http://forum.insanelymac.com/index.php?showtopic=81156

 

Still you can use WinGrub without installing EasyBCD, but if you still have problems with HFS+ error non of the method will work, you need to fix that, and it has nothing to do with the bootloader, chech the guides at Genius Bar, there is one specificaly for fixing the HFS+ error, and there are others for dual booting that cover the HFS+ error.

Well, I finally have a workaround. At least for my motherboard, ASUS P5W DH Deluxe, if you press F8 during bios boot you get a menu with all bootable devices. In there you select, for example, the windows boot drive to start windows. And that´s it. Simple. No bootloaders around. On the the next reboot, the default boot drive is Leopard.

 

Maybe other motherboards have the same feature.

LOL, re-read my post

 

That's a pretty bad solution though, since F8 drive boot menu only lists drive models. If you have same drive models, you are screwd up.

Well yes...luckily my drives are a Samsung 200gb and a Western Digital 250gb. The thing is that I don´t boot xp that much. I have that partition for the "just in case" scenario. I plan to use Parallels or Vmware.

[thefinalprophecy]

The reason you guys are probably getting that HFS+ Partition error while Chain0 loading is because you installed Leopard onto a GUID disk. Chain0 only works if your Leopard disk is formatted in MBR. I myself am still trying to figure out how the hell to install GRUB onto disk0 with windows xp and have Leopard (guid) on disk1 and boot them effectively.
