I downloaded ubuntu-13.04-desktop-amd64.

On Ubuntu's web page, I saw a link for making a bootable USB drive option, then I downloaded Universal-USB-Installer-1.9.3.3 and I made my USB bootable.

When installing the OS an error was found and installing not completed. After that I formated my USB but my USB's storage capacity reduced to 2 MB from 16 GB. How can I recover my USB size and install ubuntu.

Sorry, but your USB stick is possibly broken. I had the same issue with 2GB USB stick and nothing helped me to restore the original size. – Danatela Mar 19 '14 at 6:40
    
If you're already on Ubuntu or have access to any Ubuntu system, hook your pen drive and open Disk Utility and see if your pen drive has any partitions set. – Kushal Apr 23 '14 at 9:20
    
First use the commands in cmd, look in the comments and then i used HPUSBDISK to format the usb. – user394328 Apr 2 '15 at 18:05

Since there is no working answer yet, I post this:

The problem is that the remaining space of your USB flash disk has become unallocated. To repair it, use diskpart (in windows):

  • Open command line (cmd) and type diskpart. Allow the windows to run it.

  • type list disk, and find the number of your USB flash disk.

  • type select disk X, and type the number of the USB disk instead of X.It should say that disk X is now selected.

  • type clean.

  • type create partition primary.

Now you should be able to use the flash disk as before. (You have to format it first)

Kinda strange that you can't do this from the Disk Management console (diskmgmt.msc) – Nick T Aug 10 '14 at 21:08
    
It worked for me. – skd Jun 22 '15 at 10:41

first of all open disk management. click on removable disk or pen drive you choose. right click on it and see the total space (sum of allocated and unallocated space) if the size is less than total space then follow these step. open cmd (in administrator mode) type "diskpart" press enter type "list volume" press enter type "select volume 6"
{select the removable disk option such as 1,2,3} press enter
type "clean" press enter then exit cmd go to disk management. right click on removable disk(your pendrive volume) open new voulume then new partition wizard will start . then click next until it is finished. now see your pen drive capacity it is changed!!!!!!!

thank you for reading this !!!!!!!! please comment if it is helpful.

Use the Disk Utility that comes with Ubuntu and check that the Flash Drive's partition is actually using the whole 16gb, it may be that during the USB Installer's usage it screwed up the partition tables... To fix this you can remove any partitions inside the Disk Utility for that particular device and re-add them again ready for formatting properly...
