Can we please see the output of the following command: sudo fdisk -l. Also, when you installed Ubuntu, what option did you choose at the partitioning screen? –  Bobby May 17 '12 at 16:19

Where C: went

Type this command in a terminal window

df -h

this will list all the mounted partitions and their stats in human readable format. Look for any partitions either by size or by the "Mounted on" column that matches your "C: drive"

Take note of the size and partition number of the "D: Drive" that you can not access in windows

sda = 1st hardrive sdb = 2nd hardrive etc.
sda1 = 1st partition on 1st harddrive sda2 = 2nd partition on 1st harddrive etc.

Where D: went

In Windows click Start -> then right click on Computer -> click on Manage -> Disk Management

Here you should see any detected drives you have on your system and the partitions that are on them. You will want to leave any partition that say unknown alone as this is where Ubuntu lies. Look for any NTFS partitions that are not labeled (C:), this is most likely you missing drive. Right click on the NTFS partition and choose "Mark Partition as active". Read any warning that may appear (just in case). The drive should be given a drive letter and should then show up under Computer as expected.

The user has mentioned that he can see the Drive D from ubuntu which means that it can be seen as an external drive as also visible from the pic.The visible drive cannot be C because the OP has stated so. And if Ubuntu was installed on drive D, it would not be visible from Ubuntu as an external drive either. –  Nirmik May 17 '12 at 17:16
