[gimpbrush]

Hi,

 

My config

P5Q deluxe with beta efi bios

8 go

1 sata drive 500 go

 

i have make 4 partition with diskpart (with windows seven instal disk)

 

1) 200 Mo efi partition

2) 200 Mo msr partition

3) 20 Go primary partition (for sl)

4) 100 Go primary partion ( for seven)

 

First Part OK

Install snow leopard.

 

I use a chameleon rc3 boot disk make for snow leopard.

i swap with the retail disc snow leopard

i instal sucefully sl on the third partition

i use again the boot cd for boot in sl

i install chameleon rc3 on the third partition

when i reboot i see the chameleon prompt and i can boot on SL without boot cd

 

Second part failed

instal windows seven 7

 

 

 

 

when i try install windows seven on the 4 partition, it say windows can be installed on gpt parttion. if i start with seven installation i can install seven but macosx can boot.

 

What i must do to install windows seven and snow with dual boot support on guid partiton ?

 

sorry if i make mistake, i lack pratice in english.
