Hello,

1. Create a new runtime variable, e.g. %FINISH_TASK% and set the value to, say, 00000

2. In the Finish Dialog properties, enter your "Restart Now?" text in the "Checkbox Text" entry field

3. In the Finish Dialog properties, Advanced Tab, select the above created %FINISH_TASK% runtime variable in the "Store Selection Results in Variable" combo

4. After the last Loop Wizard, add your reboot logic:

If %FINISH_TASK% Equals "1" on Position "1" Then
! reboot logic goes here
End

That's it
