Problems booting with Chain0-File

[johnny2k]

Hi there!

 

I just try set up my trippleboot-machine (Vista, XP, OS X), but there are problems booting into OS X.

 

When I manually activate the OS X-Partition, OS X boots fine.

 

But when I try to boot it using the Vista-Loader or the NTLoader from WinXP and the chain0-File, there is just some short flickering and I'm back at the Win-Bootloader.

 

This is my partition structure:

 

 

 

I already tried everything mentioned in the Wiki:

 

1. Partition type is AFh ("HFS+", as you can see on the screenshot).

2. Boot sector seems to be valid (ends with AA55h).

3. OSX is installed on a primary partition BEFORE the extended/logical partitions (you can see that on the screenshot, too).

 

 

What else can I do to boot using chain0?

 

And don't want to activate the partition manually everytime I want to boot OS X, and I don't want to use any other bootloader either.

Put the chain0 file where your windows vista installed.

How dumb do you think I am? :pirate2: Of course the chain0-File is in the root of the first partition (Vista)!

 

 

Anyway, in the mean-time I found the real issue:

 

The Darwin-bootloader is successfully loaded by the chain0-method, but the default selection in that bootloader is the Windows OS. That's why it always jumps back to the Windows bootloader. And unfortunately there is 0-sec-timeout, so that's why I can't see the Darwin-Loader but just a short flashing.

 

So all I have to do is to edit "com.apple.Boot.plist" and change the timeout-value.

 

But how the hell do I edit that file? "nano" is not included on the OSX-boot-dvd, and I don't see any other possibility to access that partition!

I´ve got a similar problem. Triboot too (Win XP 32 bits, Win XP 64 bits and Mac OS X). 3 partitions on the same HD. chan0 is in the first one and it´s not working but I can access OSX pressing F8 while I choose Mac OS X on the Windows boot menu. When I do this Darwin loader open a menu with the 3 partitions for me to choose witch to boot to.

 

Another way to get into your OSX partition is to boot from the OSX install disk and open the terminal from there.

Here is mine version of it:

I believe vi is...

OK, I'll try that. Damnit, there are millions of f***ing Unix-texteditors, who knows them all? I tried nano and pico, but that's it.

 

On good old MS-DOS, there just was "Edit.com" and it was sufficient

Calm down, eventually you will get it working...

I've installed WinXP in the first primary partition. Installed 10.4.8 on the second primary partition. Placed the CHAIN0 file in c:\

I then edited C:\boot.ini and placed "C:\CHAIN0="Apple Mac OS X x86" and saved it.

 

What happens after a reboot, I get the XP boot menu and I select 'Apple Mac OS X x86'

The VERY next message is "Chain booting error"

The system hangs.

 

It feels like CHAIN0 doesn't know to go to the second primary partition.

 

Am I missing something?

 

Frustrated!

 

Advise, pls!

If you activate the second partition Mac OS X boots directly?

[Mac87]

Partition Magic had messed-up my initial assignments of 'fdisk'. Pobably something I did wrong. Soo I Disk Image'd my XP partition. Burned that image to DVD. Ran a good Linux rescue CD and used 'fdisk' From there assigned 3 primary partitions: First-NTFS (type 7), Second-OSX (type af) and Third-OSX(type af). I used the 3rd partition for files I wished to keep when I re-install OSX on the 2nd partition. Restored XP to partition 1. Booted and XP was happy Did a fresh install of Hackintosh on partition 2. When I rebooted, the OSX started to boot with options in(counts down...) I press return and allows me to choose which to boot First / Second / Third partition. If I choose XP, the XP bootloader askes if I want XP or Apple Mac OS X (sound familiar? it's the CHAIN0 file) and I can choose either and runs like satin sheets

 

It took awhile, hours in fact with all the preservation of my XP environment but was well worth it! Thank you MacGirl, sent me in the right direction.

Now, it's time to get some open source compiled. I've installed Xcode 2.4.1. Do I really NEED fink?

Glad to hear it worked.

 

I installed Fink in the original HD of my PowerBook, downloaded a few apps like wget, but when that disk was damaged I reinstalled almost everything but Fink, I didn't miss it, of couse this days I program very little, and with the Default Dev. Env. is enough.
