Firstly, I have my Vista OS, then I wanna use UBUNTU only, so I install Ubuntu succesfull replace to Vista OS. after that I can't boot to Ubuntu but I still see Boot WIndows menu with ERROR. I tried to use boot-repair by USB with LIVE UBUNTU and now I am typing this ASK by Ubuntu. But i had the problem that I have to chose GRUB menu with WINDOWS 7 (it show windows 7 i/o Vista lol) and Ubuntu. So i want to boot to UBUNTU not via this GRub menu directly.

Initial Default

  1. If no other operating system is detected GRUB 2 will boot straight into the default operating system and no menu will be displayed.
  2. If another operating system is detected the GRUB 2 menu will display.

Timed Display

  1. The menu is displayed for a predetermined number of seconds. The default entry is highlighted and other selections may be made by the user until the timeout expires. The default timeout is 2 seconds. The timer continues until any key is pressed or the highlighted entry is selected by pressing ENTER.

  2. If no user input is made GRUB 2 boots the default entry at the end of the timeout period.

  3. Once a key has been pressed the timeout is deactivated and the user must make a selection manually.

  4. The default entry is determined by the GRUB_DEFAULT= setting in /etc/default/grub; the first "menuentry" has a value of "0".

Hidden

  1. Normal Hidden Operations Enabled:

    1. No menu entries are displayed. The splash screen, if configured,will be displayed.
    2. The time the screen remains blank but available for display is determined by a setting in /etc/default/grub (GRUB_HIDDEN_TIMEOUT)
    3. GRUB 2 can display a countdown timer to provide visual feedback on the time remaining until the default selection is chosen. The timeout setting is enabled in /etc/default/grub (GRUB_HIDDEN_TIMEOUT_QUIET)

    4. The user may display the menu by pressing any key.

      1. Once the menu displays, the GRUB_TIMEOUT counter begins. Pressing any key stops the countdown.
        1. If no key is pressed by the end of the timeout the default entry determined by settings in /etc/default/grub will be selected.

  2. Hidden Menu Operations Not Expected (Abnormal):

    1. The user may be able to display the menu in one or more of the following ways:
      1. Holding down the SHIFT key early in the boot process until the menu displays.
        1. GRUB 2 searches for a depressed SHIFT key signal during boot. If the key is pressed or GRUB 2 cannot determine the status of the key, the menu is displayed.
      2. Pressing the ESC key during a 3 second window as GRUB 2 runs

You can follow the steps in here to change default boot entry to Ubuntu and to change default timeout: How do I set the grub timeout and the grub default boot entry?
