eskatonia Posted May 28, 2011 Share Posted May 28, 2011 Ok, thanks to some tips here I used boot 132 to install Snow Leopard from a retail DVD on an ASUS P6T Deluxe V2 with Nvidia GTX 260. Snow Leopard is working just fine, updated to 10.6.7 with no problems and enabled audio fine. I deleted my windows 7 partition when I converted the drive to GPT. So now Windows 7 installer won't install onto the spare partition I left on the GPT drive. Sorry if this is obvious, but how do I work around this and re-install Win 7 for dual boot?

3.14r2 Posted May 28, 2011 Share Posted May 28, 2011 Windows WILL NOT install on a pure GPT disk, unless: MB has UEFI 2 Windows is 64-bit U need to have a hybrid GPT/MBR disk. There are plenty of information on the subject. Please do a proper search.

eskatonia Posted May 28, 2011 Author Share Posted May 28, 2011 yes I have windows 64.... so how about answering the question? I did do a search, the answers are pretty obscure. how do I create a hybrid gpt/mbr disk? can I do that from my current state with snow leopard installed on pure gpt or do I have to start again with a different partition scheme?

eskatonia Posted May 29, 2011 Author Share Posted May 29, 2011 The answer is NOT covered in the thread you linked and is much easier than that thread talks about. I found it here on another site: http://tonymacx86.blogspot.com/2009/11/dua...-os-x-snow.html For anyone else with same problem, you don't need to use GPT fdisk or any other fiddling around. This is what worked for me. 1. Start with new drive you are prepared to wipe. 2. Follow instructions for retail snow leopard + boot 132 install for your motherboard from the installation forum EXCEPT, Format drive as GPT, create two partitions in Disk Utility when booted from Snow Leopard disk. Set one to Mac HFS+ journeled, set the other to MSFAT. 3. Finish installing snow leopard. 4. Check boots ok, run software update to go to 10.6.7, patch audio 5. Boot from windows 7 DVD (64 bit) 6. At install screen select the empty MSFAT partition, FORMAT it as NTFS from Windows 7 installer, then install to new partition. 7. Finish win 7 install, check it boots ok. 8. Windows 7 will remove the chameleon loader, so now use the boot 132 cd to boot Mac OS X , check that still works. I'm not sure if Disk Utility or windows installer converted the drive to hybrid GPT/MBR but one of them must have done it automatically. That's where I'm at, for now I'm happy using the boot 132 CD to choose to boot mac os x, I'll work out how to re-install chameleon another time. Hope this helps others, the answers are not clear in this forum, you have to read dozens of threads to work this out, a clear guide to dual boot snow leopard both on a single disk and on different physical drives would be really useful as a sticky. BTW, my system is Asus P6T Deluxe V2 with Nvida GTX260. 1 Link to comment https://www.insanelymac.com/forum/topic/258012-re-installing-win7-on-gpt-drive-after-snow-leopard-install/#findComment-1689964 Share on other sites More sharing options...
