Can you pls say me, how to get into recovery mode ? Do i need internet connection to execute those commands ?

If you have a single-boot (Ubuntu is the only operating system on your computer), to get the boot menu to show, you have to hold down the Shift key during boot up. .... Good Luck ..

I have both windows and ubuntu.

[pakidevil]

If you have a dual-boot (Ubuntu is installed next to Windows, another Linux operating system, or Mac OS X; and you choose at boot time which operating system to boot into), the boot menu should appear without the need to hold down the Shift key. From the boot menu, select recovery mode, which is usually the second boot option. After you select recovery mode and wait for all the boot-up processes to finish.

The one selected in the picture is a normal root prompt, the OP will need to use netroot (the one above it) for use with the internet.
