I am new in Ubuntu. First I installed Ubuntu 12.10 on my usb stick which is of 16 gb. So, it installed with 2 partitions of 9 and 7 gb. Now I want to format that usb. But when I try it to format, only ext4 one formatted it and not the partition which is swap memory. Now on other OS my usb shows only 8.5 gb of.
To install it, write next command in Terminal:
After you finished to install it, it will be opened now, choose your usb drive form it and can to format it or remove it and create a new one with your file system that you need.
