Stuck at GUID partition in os installation

Hi guys!

 

First of all thanks for a nice community with lots of guides and discussion. I have come quite far in creating a hackintosh but I am now stuck at a certain place.

I made a bootable usb and with some commands I am now able to enter the mountain lion installation. I can click on disc utility and see everything there.

Now is where my question comes in.

 

I have a 1tb harddrive that is split up into 3 partitions. 1 partition is for windows, 1 is a extra for backup and 1 is for mac. I named the mac partition to mac and have formatted as mac os journaled.

However, when I try to resume installation it says it can’t install on mac hdd because it needs to be formatted with GUID.

 

When I go back to disc utility the only way I can see the PARTITION thingy is when I click on the HDD top menu. But that seems to format the whole drive. I just want to partition the mac partition.

Is it because there can only be 1 MBR or 1 GUID on the harddrive? Do I need a separate real hardrive instead?

This seems to be the only thing I am stuck at. If I can fix it I hope the rest of the journey will be smooth :)

 

Hope to be enlightened

 

PS. Most of the GUID things I found does not tell you anything about multiple partitions, sorry if the info is out there and I missed it. Did alot of browsing beforehand

 

EDIT:

Seems that if I goc back to windows 7 and use a partition program, make a new partition without formatting it to anything it could do the trick. The problem is that now the hdd does not boot up windows 7 anymore so I cannot access windows 7, it misses the boot record or some such. Any suggestions here :)

 

EDIT:

Reading this: "Before you convert a disk, be sure to backup the disk that you want to convert to GPT disk. Converting the disk requires that all partitions and volumes are deleted on the disk first." Guess I need to make the harddrive to one gpt partition and then install windows 7 again....or?

I think I've seen this elswhere today trying to solve my own problems. Dualbooting a hackintosh with win 7 requires win 7 installed first but the mac osx must be installed closer to the beginning of the drive.

 

e.g. Partition 1 (Recovery [if present]); Partition 2 (MAC); Partition 3 (Windows)

 

I'm still backing data up to try this approach in the hopes it will fix my own issues

You dont need to format HDD to GUID,this is crashed Windows installacion later.

If you want to just try without a reinstall, you might can try installing chameleon boot loader. I'm not sure if you've done that already, but if all else fails, you could always do a reinstall. I never tried to dual boot way. At least not yet. I'm going to try it later tonight on my gf's dell. I just reinstalled Win7 on it and am going to try and put Lion back on it tonight as a secondary os.
