Nikitka,
Once you have selected option 3, you should select the option "back", it is number 6 I believe. The device will continue to boot. Once you are at the login prompt, use admin as the login name and leave the password blank. Execute this and you should be granted access to the device. change the password immediately for the admin account as bypassing the password only works once and then the device returns to normal operation. Let me know If you have any trouble at all.
Thank you,
Chris
