I have a 750GB hard disk with Windows 7 installed. So I shrunk the C: drive to about 80 GB, created two more partitions, one for data (about 615GB), one for ubuntu (30GB) (extended partition). I ran gparted, created a 8.5 GB swap partition inside ubuntu partition, and left whatever to ubuntu root partition. So I went to install ubuntu. After a few tries, everything worked. But now, I noticed some puzzling facts. Here are the output of a few commands:
$ df

/dev/sda7 5333936 4472688 590300 89% /

$ sudo parted -l

6 128GB 137GB 8496MB logical linux-swap(v1)
4 137GB 750GB 613GB primary ntfs
In df output, / has only about 5GB, and in parted output, there are two more partions (number 6 and 8) of 8GB each. I don't remember I ever created them. What are they? Are these disk space being wasted? How can I reclaim them?
Help is greatly appreciated.
Thanks in advance.
