## Customizing your dual-boot setup

This section briefly explains how to make basic changes to the settings of your dual-boot setup.

For directions on more advanced configuration options, see the Community Documentation page for Grub2.

### Changing the boot menu timeout

It is possible to change the length of time for which the boot menu is shown. This is useful if you would like the computer to start up faster (without the delay of showing the menu) or would like more time to choose which operating system to start. The instructions for changing the boot menu timeout are given below:

1. Install startupmanager if you have not already done so.

2. Press System → Administration → StartUp-Manager.

3. Enter your administrative password if prompted.

4. In the Boot options tab, find the Timeout section. Change the "Timeout in seconds" value to the desired length of time. Use 0 to disable showing the menu.

5. Press Close.

### Changing the default operating system to boot

You can decide which operating system will be started automatically if you have not chosen one from the boot menu within a certain time (see the section called “Changing the boot menu timeout” for more information on this).

1. Install startupmanager if you have not already done so.

2. Press System → Administration → StartUp-Manager.

3. Enter your administrative password if prompted.

4. In the Boot options tab, find the Default operating system section. From the dropdown box, choose the operating system you would like to use as the default.

5. Press Close.
