Triple boot / windows 7+windows7+fedora

[martinbayer]

Hi everyone,
I know that I can repeat quite common question but all answers I found didn't help me.
I have two windows 7 system installed (one for development and one for normal use). Next I installed Fedora 17 and I want to change grub loader to see both of windows 7 entries.
Actual behavior is that there is fedora entry and windows 7 entry which refers to windows loader where I can choose the windows 7 I wanna use.
I tried to add something like this to 40_custom file:
menuentry "Windows 7_1" {
set root=(hd0,2)
chainloader +1
}
menuentry "Windows 7_2" {
set root=(hd0,3)
chainloader +1
}

and to execute:
grub2-mkconfig -o /boot/grub2/grub.cfg

but it doesn't work.
Can you help me to tell me what I'm missing please?

Thank you very much

I don't use Windows 7. But in the past, the traditional way Windows handled the boot loader situation when you installed multiple Windows systems was that there was only one set of boot loader files, and one boot loader and menu with all the Windows systems added to it. I would bet it is still done that same old way. That chainloader thing only works when the targeted partition has bootstrapping code in its boot sector and has the BOOTMGR files in the root of the partition. That probably is not the case for both of your partitions and may not be so for either if you have a separate boot partition. Only the partition that contains the boot loader files can be booted with chainloader. It probably is possible to copy things here and there and make it so. People here learned how to do it with XP and Vista, and there are threads about it. It wasn't so easy to do then and probably still isn't. I was never convinced the benefit was worth the effort required. Another way to have one menu boot all three is to switch back to BOOTMGR as your default boot loader and use EasyBCD to add Fedora to the Windows boot menu

what does fdisk -l return?
