Why doesn't Ubuntu 12.04 recognize my Windows 7 partition?

Question

After some problems trying to install Ubuntu alongside Windows 7, now I have Windows 7 installed and it works just fine. But when I am going to install Ubuntu it doesn't recognize my windows.

What should I do to see Ubuntu in my PC? My Ubuntu version is 12.04 64 bit.

PC specs:

Asus crosshair IV formula 
AMD phenom II x6 1055t @ 4.1GHz
Corsiar 4x2Gb 1766 @ 9-9-9-24
AMD Radeon 7870 GHz edition
WD 1TB caviar black

After boot when ubuntu coming up it says you don't have any OS installed on your system while i have windows 7 ,so there is no option like install ubuntu along side windows 7 !! — Ramin, Mar 07 '13 at 21:32
Ubuntu doesn't care if you have any other operating systems installed, can you provide a picture? — Soroosh129, Mar 08 '13 at 00:51

The usual cause of the "missing partitions" problem is one of two things:

A damaged partition table -- On an MBR disk, my FixParts program can usually fix such problems. See the FixParts page for details on how to use it. It's usually just a matter of launching the program on the disk, typing p to verify that it's detected your partitions correctly, and then typing w to save the fixes.
Leftover motherboard-based software RAID data -- This can usually be fixed by typing sudo dmraid -E -r /dev/sda, IIRC, changing the device filename as necessary. You may also need to go into your firmware setup to disable RAID. Of course, if you're actually using RAID you should not do this!

It might be there, just not showing up yet in Nautilus. Try mounting the drive.

In terminal:
sudo blkid - ( get the uuid of the drive)
sudo mkdir /media/<mount point> << create the mount point, media is default
sudo gedit /etc/fstab
Proper fstab entry to mount a samba share on boot?

UUID=Put_UUID_Here /media/win ntfs rw,auto,users,exec,nls=utf8,umask=003,gid=46,uid=1000 0 0

I fail to see how the samba share part is relevant, they're not trying to mount a share. – Thomas Ward Mar 07 '13 at 18:22

When installing Ubuntu, choose the Something Else option. (on the bottom of the screenshot below)

enter image description here

This will show your Windows partitions, and allow you to install Ubuntu on other partitions. See https://help.ubuntu.com/community/GraphicalInstall#Installation_type

You say: "when I am going to install Ubuntu it doesn't recognize my windows". This suggests to me that your problem is similar to the one described, for example, in this question: Dual boot ubuntu 12.10 and windows 8 Dell Inspiron 15 r

If so, the answers to that question may be helpful.

I had the same problem with my laptop that originally have Windows 8 (using GPT) that I installed Windows 7 (using MBR) on. I found the solution here...

After so much time messing around with Windows, Ubuntu feels great!
