Partition is missing in My computer

In my computer, I can't find one of my partition... And in disk management i can find the partition with missing driveletter and name and shows as empty drive and it doesn't show any filesystem name .... And i used to easeus partition recovery to find the partition status , There i find my partition(missed) partition as *(NTFS) and amount of free space with correct attributes and i can see all the files and folders through that software.. But this software did not show recovery option as the partition is already exists in the system..... Tell me how can i get my partition back without losing any data

Please post back a screenshot of your maximized Disk Management drive map and listings:

1. Type Disk Management in Start Search box.
2. Open Disk Mgmt. window and maximize it.
3. Type Snipping Tool in Start Search box.
4. Open Snipping Tool, choose Rectangular Snip, draw a box around full map and all listings.
5, Save Snip, attach using paper clip in Reply Box.

Tell us what is on each partition.

Thanks for the reply Mr.Gregrocker The partition which is missing is the partition with 105 GB storage capacity
When i use easeus partition recovery it shows everything right about the partition the amount free space, occupied space and can see the contents of the partition.... I want to recover the partition without losing the data in the partition

The Disk Mgmt listings show that partition is empty.

If empty as shown I would use free Partition Wizard bootable CD which is the only disk manager besides Disk Mgmt which will not fail. Partition Wizard Partition Recovery Wizard - Video Help.

After you recover that last partition ask back if you'd like help apportioning more space to C which is absurdly small. We will show you how to do this while resizing and moving over the other partitions.

Thanks for the reply Mr. Gregrocker No, I am not deleted the partition data ... In the screenshots it shows the partition is exists when i explore the partiton using this software ,i can see the data stored in it exactly how it was when everything is fine... The problem occured due to " i install ubuntu and windows 7 in dual boot" and deleted the ubuntu partition without making changes to MBR " so i am not able to boot, I tried recover using norton ghost using the recovery point but it is failed" so i performed a clean installation of win 7 again... After that i lost that partition ..... see the screenshots clearly , I dont know the problem correctly whether it is due partition table corruption or file system corruption.....

The Disk Mgmt listings show the partition is empty. Easeus is not more reliable than Disk Mgmt, but PW boot CD can be so I would compare it now.

See if in PW you can assign a drive letter and it should be accessible via Explorer.

That PC shipped with Vista. How are you activating Windows 7 Ultimate?
