Installation of ML and W7 one same disk (GPT Guid)

[nioyco]

Hi guys,

After deleting all partitions for a clean install of OSX on my Laptop (with the disk tool i prepared the 1st for OSX and a 2nd one for W7), installing Mountain Lion, now i can't restore/install my windows partition because of the GPT type who seems to be not supported by 'crosoft...

Before (snow leopard and lion) i done a tip to install OSX with MBR, is it still needed?!

Do you know an other solution ?

Thx

I find a solution :

In disk tools of ML i format the (future) windows partition in FAT.
I reboot on windows install disk. It still says me it's not possible to install on the disk in GPT.
BUT : format it directly the FAT partition with button and it's possible to click on NEXT and install windows on it !
