the windows in sda2 is a recovery or something and the install is sda3. It looks like sda3 has all the boot files but the boot flag is on sda2. Boot flag does not effect grub as it just jumps to the partition boot sector. Windows boot loader in the MBR needs to see the boot flag (active partition) to know what partition boot sector to jump to to continue booting.
Did you try booting sda3?
If not, move boot flag to sda3 and try windows repair tools. You can use gparted, disk Utility or command line.
set boot flag on for sda3 (off for others)
sudo sfdisk -A3 /dev/sda
It also says you have SFS partitions, which are a windows proprietary type but still NTFS. This sometimes has caused issues as I think windows stopped using it.

If in windows repair you run fixMBR you will overwrite grub. That is ok if you want to confirm that windows boots ok, but you will have to reinstall grub2 to the MBR.

sudo mount /dev/sda4 /mnt

If that returns any errors run:

Hello,
If you could help me on my problem i would really appreciate it.
I installed ubuntu 11.10 and i ended up messing my windows boot. I followed the boot_info_script part and i am attaching the info below:
So my win 7 exists on sda4 and the boot files are missing. How do i install the boot files on it and get back my windows ?
Thanks in advance,
