w.jeffrey Posted November 19, 2006 Share Posted November 19, 2006 I'm currently running JaS 10.4.6 on a 320gig SATA harddrive. I recently bought an 80gig SATA harddrive to install Windows XP on it. After installing the harddrive, I booted up my computer, entered bios, switched my first boot device to my DVD drive. I popped in my Windows XP cd, and it booted up from the cd as expected. Preparing for the installation, XP asked me which harddrive I would like to install on. It listed my 320gig and my 80gig. The 80gig had no install system type, and I selected it. My problem occurred in the next step. Windows XP wanted to partition my OSX harddrive by a small amount (a few megs i think). I suspected it wasn't safe to have Windows play with my OSX drive so I quit the install. As of now, everytime I boot up in OSX, I get a notification window about my new drive, but I simply ignore it, seeing as the drive hasn't been formatted into anything. I was wondering if anyone could provide any help as to what to do in my situation. I would like to dual boot OSX and Windows XP, each from different harddrives. Sorry for the long post, I just wanted to be as clear as possible. If I've made anything unclear, please don't hesitate to ask me. Thanks in advance!

Renard45 Posted November 19, 2006 Share Posted November 19, 2006 Install XP first and after OSX then after this you will have dual boot with the darwin boot loader after editing the com.apple.boot.plist Link to comment Share on other sites More sharing options...
w.jeffrey Posted November 19, 2006 Author Share Posted November 19, 2006 I've already had OSX installed and have been running it for some time. I have a harddrive just sitting in my computer, waiting for XP to be installed on it. I just don't know if it's safe to proceed with the XP install because it wants to partition a bit of my OSX drive. Link to comment Share on other sites More sharing options...
Renard45 Posted November 19, 2006 Share Posted November 19, 2006 if you want to install XP (if you have OSX already install) XP can not see your OSX partition because he doesn't know the format then make sure you 're installing XP on the right hard disk drive sorry for my poor english i'm a french user Link to comment Share on other sites More sharing options...
w.jeffrey Posted November 19, 2006 Author Share Posted November 19, 2006 It's strange because in the XP install, it sees my other harddrive that has OSX on it. I'm sure I've selected the correct drive to install XP on. It still insists on partitioning my OSX harddrive by a few megs to install some (system/boot?) files.

Renard45 Posted November 19, 2006 Share Posted November 19, 2006 very strange ! for me when i have tested different installs xp see the OSX partition but he believe the partition is unformatted Link to comment Share on other sites More sharing options...
w.jeffrey Posted November 20, 2006 Author Share Posted November 20, 2006 If I understand correctly, I'd go ahead and install XP and it would make the partition in my OSX harddrive. After the installation was complete, and restarted my computer, it would load straight into XP? I would then have to fix my bootloader and master boot record in order to get dual boot working correctly? Is that where Darwin Bootloader and com.apple.boot.plist come in? I'm not too clear on that, coud you help clear it up for me? Thanks again Link to comment Share on other sites More sharing options...
Renard45 Posted November 20, 2006 Share Posted November 20, 2006 Take the Ultimate boot cd to fix the boot to boot to the OSX partition and after in the OSX system edit com.apple.boot.plist with the option <key>Timeout</key> <string>30</string> to have time for switch between XP or Mac OSX Link to comment Share on other sites More sharing options...
t-squared Posted November 20, 2006 Share Posted November 20, 2006 Just disable your OSX drive in BIOS, or physically remove it, so Windows doesn't see it on the install. You'll then have to figure out how you want to dual boot the two systems: you can use something like Acronis OS Selector, or you can modify the boot.ini on your windows drive to see both OS's. There are plenty of posts on this and other sites that will tell you in detail how to accomplish both options. I think the problem is Windows is seeing your current drive as the Primary Master, and is trying to install its MBR to that drive. Link to comment Share on other sites More sharing options...
joe75 Posted November 20, 2006 Share Posted November 20, 2006 You only need to install Windows. XP will tell you there is a active disk and ask you for permission to set it inactive so it can install. After the install you will need to set osx86 disk back to active in diskpart. If you have hps+ error when trying to boot, just boot from OS X install DVD and fdisk in terminal Link to comment Share on other sites More sharing options...

w.jeffrey Posted November 20, 2006 Author Share Posted November 20, 2006 Nice, glad to hear it. Question for wondergod. After you installed XP, did you just shut down and re-enable your OSX harddrive? And if so, once you rebooted, did you just have to set harddrive priority?

wondergod Posted November 20, 2006 Share Posted November 20, 2006 ok...it was a while since i did it...but if I recall... I had mac os on primary hard drive...I disconnected it and set my xp hard drive to primary then installed xp...I think after that I set my mac os to secondary...and set my xp to active...then when xp booted up I installed Acronis Disk Director... I'm not to sure...what the exact order was...sorry suggestion: Get the ultimate boot CD because it has a boot manager in case you mess up you can temporarily change the boot partition with it in case you screw up Link to comment Share on other sites More sharing options...
