PlayingKarrde Posted October 4, 2006 Share Posted October 4, 2006 So thanks to Rammjet I can now use windows again, but I'm still having problems with my OSX86 installation. The problem occurs when I set the partition as active. It gives me an MBR error and asks me to reboot. I've also tried with Acronis Boot Manager and the chain0 method but OSX doesn't show in either. I've read the numerous threads about installation and followed to a tee. When looking at the OSX partition in Acronis Disk Utility it tells me it is Primary. When using diskpart it tells me it is unknown. Any joy from the knowledge at hand? It's been 4 days since I started trying to install OSX86 and I can't give up until I at least boot my lappy into Apple's buxom. Thanks in advance.

Rammjet Posted October 4, 2006 Share Posted October 4, 2006 Try booting your install DVD and select Terminal in the Utilities menu. Type: fdisk -u /dev/rdisk0 Reboot. Link to comment Share on other sites More sharing options...
PlayingKarrde Posted October 4, 2006 Author Share Posted October 4, 2006 Do I need to make it active first? Link to comment Share on other sites More sharing options...
Rammjet Posted October 4, 2006 Share Posted October 4, 2006 No, but if you don't have a working bootloader on the Windows partition, you will need to make the OSX partition active to boot into it. Link to comment Share on other sites More sharing options...
Mebster Posted October 4, 2006 Share Posted October 4, 2006 If you already have OSX installed and what he has said is actually repairing your installation then yes, you may have to I would assume. But first just type what he stated and reboot. If nothing happens then make OSX your active partition and try there. If nothing happens then bring it back and make windows your active partition. To make your system active you will need a boot disk such as fdisk. Link to comment Share on other sites More sharing options...
Rammjet Posted October 4, 2006 Share Posted October 4, 2006 When you are booting from the install DVD as I have said to do, the install DVD is the one that is active (booted). You only need to set a partition active to tell the BIOS which partition to boot. It won't have any effect on repairing the MBR which is not on either of the partitions - it is on its own tiny partition at the beginning of the hard drive. Once you repair MBR, then you need to set whichever partition contains the bootloader to be active so it gets booted. If your bootloader is on the Windows partition (Acronis or Chain0) then set the Windows partition active. If you are using the OSX bootloader (Darwin), then set the OSX partition active.

PlayingKarrde Posted October 4, 2006 Author Share Posted October 4, 2006 Well I'm not getting the error anymore... but I'm not getting OSX either. Acronis shows only Windows and even with Chain0 I don't get any option. This is with the OSX and windows active (ie tried with both)... Ideas?

PlayingKarrde Posted October 4, 2006 Author Share Posted October 4, 2006 One thing of note, I'm getting this error when loading Partition Magic: "Partition didn't begin on head boundary." I get this error with no other partition programs. This is on my logical drive which I moved to be after the OSX partition (so both Primarys were at the start). Will this be causing my problem? If so it looks like a complete reformatting with a completely clean Windows and OSX will be necessary. *sigh* Link to comment Share on other sites More sharing options...
Rammjet Posted October 4, 2006 Share Posted October 4, 2006 When you set OSX active and try to boot into it. Does it just go to Windows? If so, the Darwin bootloader is defaulting to Windows and since you cannot see the bootloader, you cannot select OSX. Boot the OSX install DVD. Hit F8. Select your OSX partiton and hopefully boot into your OSX installation. If you succeed, then do this: http://forum.insanelymac.com/index.php?s=&...st&p=188186 After that, be sure to set your OSX partition active.

PlayingKarrde Posted October 4, 2006 Author Share Posted October 4, 2006 I guess I should note that previous times I've hit F8 (such as to use -v) it has only said the OSX boot DVD. I will try again, but my thoughts right now are a complete removal of all partitions and starting completely from scratch (backing up as we speak) Link to comment Share on other sites More sharing options...
