F17 Installed - no dual boot with win7 :(

[Reptar]

Hello i just installed Fedora 17 today.

I want to use dual boot with win7 but after the installation only fedora was shown in grub bootloader.

i tryed grub2-mkconfig. Doesnt helped.

I have 2 NTFS Partitions. One for data and one with win7.

here my partitions:

dev/sda1 vfat DELLUTILITY
dev/sda3 ntfs win7
dev/sda4 ntfs datapartition
dev/sda5 swap
dev/sda6 ext4 _Fedora-17-x86_6


I edited /etc/grub.d/40_custom to

(i got the 844... from dolphin)

after that i tryed grub2-mkconfig again, doesent helped.
(tryed it with msdos2 too)

i downloaded grub-customizer saw my win7 entry put it on the top and it was shown in the bootmenu

but then "bootmgr missing press ctrl alt to restart"

Iam a big beginner / dont have so much linux knowledge yet

help me guys !

Is this a UEFI system? There might be something hidden in /dev/sda2 if it's not an extended partition.

What's the output of this command?

parted -l
