Hi! I've got a question: can I change string "Goodbye." in Shutdown and Reboot function?

There is no string in os.shutdown nor os.reboot, however the "shutdown" and "reboot" programs (which are not normally editable). You could create your own shutdown or reboot program very easily, something like this:
print( "Goodbye." )
sleep( 5 )
os.shutdown()

How can I do special field for text? Like a registration.
If it is possible write a example code :)/>

What do you mean? Something like password? If yes then use this
PassInput = read()
If passInpit == standartpass then
Do something
End
PassInput = read()
If passInpit == standartpass then
Do something
End

Try this: (this will make username visible and password be *):
print("Username:")
local username = read()
print("Password:")
local password = read("*")

Srry for my bad english. I did not mean that you recommend for me.
Something like this, but in CC:
When I left-click on "field", I can write a text, password or username. I see something like that in CC, but I don't see a code

To give a better explanation, you have to code that directly into your script. You can pull mouse_click events to check if the field is selected or not, key events to check for tab/return, and char events for letters/numbers/symbols. Then it's a simple issue of keeping track of what they've typed in a string, rendering appropriate bits of the string in the text field, and moving the cursor.
A good way to figure out some of this is to simply read the source code for "read()"
Note: I wouldn't recommend writing this from scratch if you don't have a good knowledge of Lua or CC. It may be easier to use an API written by someone else.

What do you mean? If you mean the
That's not settable.
If you mean the computer label, os.setComputerLabel.

Errors in window are generally triggered by mis-used term functions.
I notice you're doing this sort of thing in drawSelection():
But centerText() is declared as:
You've got text / coord mixed up, so you end up term.setCursorPos()'ing your text. There may be similar errors elsewhere in the script, but you should now know what to look for if so.

What do you mean by "Computer is crashed"? I ran the installer, selected exit, and it simply cleared the screen and returned to the shell, as I expected.
