Amir Posted January 4, 2006 Share Posted January 4, 2006 I have installed OSX 10.4.3, it works fine. But its installed on Logical harddisk not primary. On my primary partition i have installed windows XP. I have tried chain0 method but it kept comming back to OS selection menu again and again. Here is how i have divided my partitions 1- Primary (Windows) 2- Logical on Extended 3- Logical on Extended (OSX) I cannot set OSX to be bootable as it should be Primary. Any idea how can i boot my OSX. I have tested it works fine otherwise ITunes and others are quite speedier.

Technobob Posted January 4, 2006 Share Posted January 4, 2006 (edited) I think Mac needs to be on a primary partition not a 100% sure on that. What I do is I use the Disk Utility in the Mac installer and create my partitions from there. I don't let the installer go any further. I restart my computer then install windows on the first partition then when thats done I install Mac on the second partition. Doing it this way I can select XP from the Darwin boot loader if I need it. I run Mac on my laptop 99.99% of the time so I have it as default boot. If you want XP as default you will still need chain0 option.

macgirl Posted January 4, 2006 Share Posted January 4, 2006 If you convert your extended partitions to primary Mac OS X can be booted directly if it is activated or with the Windows Bootloader with chain0, or other bootloaders.

DrJägermeister Posted January 5, 2006 Share Posted January 5, 2006 how do you convert your partitions from logical to primary? Don't know if this is possible (logical -> primary). At usual I delete the logical partition and the extented first, to create a new primary. After that I only create an extented with the logical partitions for data.

suleiman Posted January 5, 2006 Share Posted January 5, 2006 okay, here's my situation: I've got 3 partitions with the following configuration: 1: 13 Gig FAT32 with XP installed on it and set to Active Primary partition 2: 4 gig FAT32 with no OS installed, and set as a primary partition 3: 20 Gig extended partition which is set to Primary BUT also has a 20 gig partition showing up as type AF (apple filesystem) underneath it in Partition Magic. This sub-partition is set as a Logical Partition. Since my XP partition is set to be active and primary, i'm booting off of it just fine, and I even have chain0 setup and working great, but everytime I go to Mac OS X from the XP bootloader, I'm getting sent immediately back to the XP bootloader screen, as if nothing even happened. It seems as though it can't find the right drive to boot OS X from, or at least a boot sector. What i've done so far is delete the 20 gig partition in Ubuntu and format it as type AF. When I check in the Ubuntu terminal, I can even see that the partition i've formatted is set as a Primary partition, but what happens is after I install OS X, it re-sets the partition as a Logical partition. So far i've spent about 8 hours trying to get 10.4.3 to install...where 10.4.1 happened instantly for me. This is officially driving me insane.

I had a simillar situation after I changed XP in w2k (new install) on a dual boot. When I choosed OSX86 I had to press F8 for the darwin bootloader (else I was back in NT bootloader), and choose the OSX86 partition to boot from. Once OSX86 had boot I had to change the startup disk from W2k in OSX86 (the w2k install had changed this?), now OSX86 was booting with the NT bootloader. A extented partition set to primary? At usual I have (up to 3) primary partitons and one extented in witch the logical partitions are located. If you have a linux Live-CD take a look with fdisk -l. As I know OSX86 need a primary partition (not 100% sure).

suleiman Posted January 5, 2006 Share Posted January 5, 2006 thanks alot man, following your instructions (pressing F8 very quickly) I was able to access my OS X install. But what can I do to keep this from being a recurring thing? You suggested changing the startup disk once I get into OS X, but what would I set it to? Right now I can set it to boot from Windows or from OS X, but whenever I set it to boot from my OS X partition then the system comes up with a message saying It can't find an operating system to boot to, and then I end up having to reinstall XP so that it works again. Any ideas? Link to comment https://www.insanelymac.com/forum/topic/6423-osx-logical-harddisk/#findComment-39983 Share on other sites More sharing options...

Any ideas? That shouldn't happen, maybe it's due to the partition (logical until primary) that OSX can't set itself as startup disk.

suleiman Posted January 5, 2006 Share Posted January 5, 2006 nevertheless, could you tell me where within OS X you set the option for which disk to use for your startup? I've been snooping around Disk Utility and haven't had any luck yet. edit: nevermind, I was able to simply edit my com.apple.boot.plist file so that I had a timeout value of 6 instead of 0. So very bizarre how it would have deleted that option! Now i'm off to configure my 10.4.3 install...thanks for all your help!

JoeP Posted January 5, 2006 Share Posted January 5, 2006 don't use MacOS's Startup preferences yet, especially in your case with MacOS installed on an extended partition. I did the same and had to fix the partition table with a Linux liveCD, it was too much stress! the F8 trick works great, go on like this until you'll reinstall. my girlfriend has no problem with typing F8 quickly after choosing macos in the windows boot menu. when i'll reinstall the whole thing (if ever i do, since it works like a charm now!), i'll delete the extended partition and create primary one instead.
