How to increase the partition size of Ubuntu 14.04 installed under Windows 7?

Question

I have windows 7 as primary OS. In past year I installed Ubuntu 14.04 from live USB. I don't use Wubi. Now I have to increase the partition /dev/sda6 size of Ubuntu.

user:~$ df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda6        16G   15G  275M  99% /
none            4,0K     0  4,0K   0% /sys/fs/cgroup
udev            3,9G  4,0K  3,9G   1% /dev
tmpfs           785M  1,2M  784M   1% /run
none            5,0M     0  5,0M   0% /run/lock
none            3,9G  372K  3,9G   1% /run/shm
none            100M   44K  100M   1% /run/user
/dev/sdb1       279G  215G   64G  78% /media/user/035F3F68B14AD251

Update.

denis@denis:~$ sudo parted -l
Model: ATA Samsung SSD 840 (scsi)
Disk /dev/sda: 256GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number  Start   End    Size    Type      File system     Flags

And:

denis@denis:~$ lsblk

sda      8:0    0 238,5G  0 disk

├─sda5   8:5    0   7,9G  0 part [SWAP]
└─sda6   8:6    0    16G  0 part /
sdb      8:16   0 298,1G  0 disk 
├─sdb1   8:17   0   278G  0 part /media/denis/035F3F68B14AD251
└─sdb2   8:18   0  20,1G  0 part

Add the output of sudo parted -l and lsblk as well, please. — muru, Apr 29 '15 at 12:39
@bodhi.zazen, may be that way will be work fine. But it sounds so complicated. I have to 1) download ubuntu iso; 2) make live usb; 3) perform set actions. Is there more simple way to complete my task? — Denis, Apr 29 '15 at 13:03
"installed under Windows 7?" explain that with "no wubi" please? — Rinzwind, Apr 29 '15 at 13:11
@Rinzwind, when I installed Ubuntu, installer said to me: "You have Windows, let I install Ubuntu near with your Windows". I think, that it is not wubi, but I may be wrong. — Denis, Apr 29 '15 at 13:14
You can not resize your ubuntu partition when you are using (booted into) it or from windows. So a live usb is the only option. — Panther, Apr 29 '15 at 14:50
@bodhi.zazen, it sounds sad. But, thank you for information. — Denis, Apr 29 '15 at 15:16

First install Gparted if you have not already by:

sudo apt-get install gparted

and resize your 230GB windows partition (NTFS) to make unallocated space (you can decide the size of this partition). Do not make any changes to Ubuntu partition while you are logged into Ubuntu.

If you have live CD or USB with ubuntu boot from this and run Gparted from there. Now, merged this unallocated space to Ubuntu.

Also, just in case make sure you have make a copy of Boot-Repair and use it in case this procedure messes up GRUB (there won't be a problem generally, but who knows!)

Generally speaking it is better to resize you windows partitions from within windows rather then a live usb or from Ubuntu. Doing so prevents a number of problems wiht windows. Often you have to defragment the windows partiton from windows first. — Panther, Apr 29 '15 at 13:00
