boot manager windows with blue stripe above and gray body with 3 options that i dont even know what it means

one option is name "start windows normally".. what are the other 2 options?

If you select "start windows normally" all is fine (expect the 3 options all the time if booting)?

If your computer fails to shutdown properly, the Windows Error Recovery screen is shown automatically the next time you start the computer. You then have the option of starting the computer in one of several Safe Modes or using normal startup.

The last option occurs?
