Snow Leopard dual boot with windows 7 but with windows 7 previously installed

[ltkenbo]

I have an Asus P6t motherboard currently running windows 7 and I was following this guide to install Snow leopard:

http://www.insanelymac.com/forum/index.php?showtopic=189052

 

What I did on windows was shrink the partition space and format a FAT32 partition, I then booted off the jump drive as in the guide and used the disk utility in OS X installation to format it to Mac OS Extended (Journaled), I then format it and return back to the installer where it will let me choose the partition to install to. However in both partitions (even the one formatted for OS X) it has a yellow exclamation mark and triangle and the install button is greyed out and it says:

 

"To install on this disk, open disk utility by choosing utilities > disk utility, and repartition this disk using GUID Partition Table. Important: you willl lose all data on this disk by repartitioning it."

 

So I understand if I reformat the whole drive using disk utility and ensuring to format using GUID partition table it will install but is there any way to install to a partition without reformatting my whole hard drive? I don't want to do that because I will have to back up everything and reinstall everything.

 

I've looked on the forum and on the internet but most guides with dual booting seem to talk about from the ground up with a fresh installation and format of the hard drive. Please help. Thanks.

Open disk utility from the distro boot cd you are using. Locate the partition you want to install MACos to. Change the name of the partition and choose erase using Mac OS Extended (Journaled).

Then you can return to continue the installation as MacBoot will now recognise the partition and install into it.

 

Hope this helps.

 

 

PS don't forget to install chameleon boot loader after the mac install to help you dual boot.

Only thing I did differently was not change the name. Wouldn't think this would make much of a difference.
