Disk /dev/sda: 500GB
Sector size (logical/physical): 512B/4096B
Partition Table: msdos
Number Start End Size Type File system Flags
1 1049kB 106MB 105MB primary ntfs boot
2 106MB 105GB 105GB primary ntfs
3 105GB 315GB 210GB primary ntfs
4 315GB 500GB 186GB primary ntfs
On the other hand, there is a lot of free space in partitions 3 and 4 as can be seen in the output of df
Code:
=================== df -Th:
Filesystem Type Size Used Avail Use% Mounted on
...
/dev/sda1 fuseblk 100M 25M 76M 25% /mnt/boot-sav/sda1
/dev/sda2 fuseblk 98G 36G 62G 37% /mnt/boot-sav/sda2
/dev/sda3 fuseblk 196G 13G 183G 7% /mnt/boot-sav/sda3
/dev/sda4 fuseblk 173G 8.6G 165G 5% /mnt/boot-sav/sda4
The two first partitions are important for your Windows installation, and should be kept unchanged. See this summary:

I think that you can copy whatever data there is in the third partition, /dev/sda3 into the fourth partition /dev/sda4, and then backup everything or at least all your personal data to another drive for example an external drive (USB drive).
Editing partitions and installing operating systems is risky. If you have bad luck, you need the backup to be able to restore your system.
Start gparted when booted from the Ubuntu install CD/DVD/USB drive.
1. Delete the third partition (the data from there should be in the fourth partition now).
2. Create an extended partition in the unallocated space (which was used by the third partition before).
3. Create a logical partition slightly larger than your RAM. For example, if you have 4 GB RAM, make it 5 GB. Use it for linux swap.
4. Create a logical partition of the rest of the unallocated space in the extended partition. Format it to the ext4 file system. Use it for Ubuntu's root file system '/'.
5. Start the installer and install Ubuntu. At the partitioning screen, select Something Else, and select the partitions, that you prepared with gparted (the root partition and the swap partition).
6. At the bottom of the partitioning screen, make sure that the bootloader will be installed to the head of the drive, where the partitions are, /dev/sda There should be no [partition] number, only the drive letter, which means that you install the bootloader into the head of the drive.
7. Continue the installation ...
