Hi, thanks for your help Zane.
I have one HDD on my laptop, the first partition is for OS X, the second one is for W7, the third partitions is for Linux, and the fourth is an extended partition for data in NTFS.
When i installed OS X, the bootloader only shows me to start OS X and the extended partition, but it havent any boot archive.
If I start with the installation iaktos DVD, it shows me the W7 partition as MSDos-FAT, but its really NFTS partition as show me G-parted live CD and partition manager if I start W7 with superdiskgrub.
Before to try OS X, i had XP, W7 and ubuntu 10.04 and I always install ubuntu the last, and the boot of ubuntu shows me all the OS's. How should be the installation of the SO's? OS X the last?
I already have OS X partition active, but it dont recognize the W7 partition.
I think that the problem is chamaleon bootloader it installs on partition MAC journaled, not to MBR.
Thanks again.
