Fedora 16 & Win 7 Dual Boot Problems

So I wanted to create a dual boot with the latest Fedora (16) and my current Windows 7 installation. I installed the desktop iso (3.5gb) from a usb drive and in my inexperience with non-windows operating systems, must have messed something up bad.

At first, no OS would load up, never got an option for Fedora and Windows failed to load. Then marked the partition as active and grub loads up. Fedora boots and works fine. I can even see the files from my windows installation.

But Windows 7 still won't load when I try to load it from grub. I have a recovery disk and when I try to boot from it to fix the MBR (by using Bootrec.exe /fixmbr from the recovery console) it doesn't recognize any operating systems. I tried using Bootrec.exe /fixmbr from the console and it didn't seem to do anything. Also, Startup Repair doesn't do a thing either, just says it can't fix the computer automatically.

Also, I've seen that the fdisk -l output is usually asked for, so here it is:

[root@localhost ~]# fdisk -l

Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xf2b66014

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1              63        2047         992+  42  SFS
/dev/sda2            2048      409599      203776   42  SFS
/dev/sda3          409600   889909247   444749824   42  SFS
/dev/sda4   *   889909248   976771119    43430936   83  Linux

I appreciate any insight that can be offered as I'm completely inexperienced in both dual-booting and the use of linux operating systems.

I have a multi-boot setup that boots Windows 7, F16, and two other linux distros using Fedora's GRUB2 boot loader installed to the MBR. My setup is as follows,

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *          63   136713149    68356543+   7  HPFS/NTFS/exFAT
/dev/sda2       136713150   137098709      192780   83  Linux
/dev/sda3       137098771   625137344   244019287    5  Extended
/dev/sda5       137098773   163091879    12996553+  83  Linux
/dev/sda6       163091943   181084679     8996368+  83  Linux
/dev/sda7       181084743   183590819     1253038+  82  Linux swap / Solaris
/dev/sda8       183590883   209583989    12996553+  83  Linux
/dev/sda9       209584053   219158729     4787338+  83  Linux
/dev/sda10      219158793   245151899    12996553+  83  Linux
/dev/sda11      245151963   254726639     4787338+  83  Linux
/dev/sda12      254726703   625137344   185205321    7  HPFS/NTFS/exFAT

I believe the Windows partition must be marked as active for Windows 7 to boot, that may be why your Windows recovery disk doesn't detect any operating systems. Set your Windows 7 system partition as the active boot partition and try your recovery disk again.

Are you sure that you've installed grub to the MBR of /dev/sda? You could try reinstalling F16 and ensuring that grub is installed to /dev/sda, and NOT your Fedora partition.
