[Help] Booting with XP & OSX

[DruDragon]

Hi, i have finally got mac os x86 running, i followed some "READ_ME_FIRST" guide and created the partitions necessary for installing XP & OSX. Right, after finishing the installation of XP, i restarted the comp only to find that i don't have a choice to choose Mac OSX, it boots straight into windows.

 

However, when i check the partitions after, it shows the partitions that i created, (that is one for XP one for MAC OSX).

 

Now, i would like to know:

 

1) How do i get the darwin option at startup to appear so i can choose which OS to boot up.

2) Secondly is it possible after doing this where the comp boots up Windows XP as default and Mac OSX as a second selection from some option list like darwin???

 

Please help, i have been trying to figure this out all day, and have read all the dual boot guides with no success!

You installed in the wrong order you must install XP first then Mac.

It's not all lost do a seach for setting up chain0 option.

Doh, i just followed a guide by BB titled "READ_THIS_FIRST", and that;s the order he specified, any way thanx for the help, i will try that and report back if i have problems!!

 

Also is it possible after doing this where the comp boots up Windows XP as default and Mac OSX as a second selection from some option list like darwin??? As i use XP more but would like the option of choosing OSX

I beleive when you use the chain0 option you can set what boots first. I have never used it so I don't know anything about it.

IF you have 10.4.3 you can use F8 during startup to select which partition to boot from. But you have to use it before the apple logo screen.

Don't panic. All is not lost. I don't believe it matters the order in which you install your OSes as you can always change things around. First - squirrel away your /usr/standalone/i386/chain0 somewhere (like a flash key or somewhere on the network) as you'll need it after you get XP installed. If you are running 10.4.3, it might help to add a time delay in the darwin boot loader. Add the following lines to your /Library/Preferences/SystemConfiguration/com.apple.Boot.plist file before the </dict> line:

 

<key>Quiet Boot</key>

<string>No</string>

<key>Timeout</key>

<string>7</string>

 

After XP is up and running, copy the chain0 file to c:\ and add this line at the end of your c:\boot.ini file:

c:\chain0="OSX86" or whatever you want to call it. Also increase the timeout value in the boot.ini file. When you reboot, you now have a choice. The default do nothing option will boot XP. If you select OSX86, you will then invoke the darwin boot loader. On my system with the original com.apple.Boot.plist file, the darwin loader wouldn't work right and handed you back to the windows boot loader. Adding the above time delay gives me the option of booting OSX or XP.

 

I couldn't figure out how to configure the Darwin boot loader to select XP as the default so I had to use the XP bootloader with chain0 to accomplish this.

 

Now to help your particular case of being stuck in XP and probably not grabbing chain0 before you installed. You can boot from the OSX86 install DVD again. When the installation is up such that the menus appear at the top, there's a menu that you can select which will choose which OS to boot. Select OSX86 and reboot. This basically marks whatever partition you select as active. There is probably a windows way of doing it (like fdisk?), but I can't offer any help there. Once in OSX86, follow my above directions and you should be set. You'll have to use the Startup Disk item in System Preferences to select XP.

 

Hope this helps...
