BOOT METHODS

Available boot methods:

expert

Minimal command-line system install.

Try Ubuntu without any change to your computer

To use one of these boot methods, type it at the prompt, optionally followed by any boot parameters. For example:

If unsure, you should use the default boot method, with no special parameters, by simply pressing enter at the boot prompt.

("Ubuntu" may be replaced with other related operating system names. This help text is generic.)

To use one of these boot methods, select it from the menu with the cursor keys. Press F4 to select alternative start-up and installation modes. Press F6 to edit boot parameters. Press F6 again to select from a menu of commonly-used boot parameters.

Except in expert mode, non-critical kernel boot messages are suppressed.

rescue

There is no dedicated rescue mode on this disc. However, since the disc provides a complete user environment, it is possible to use the command-line and/or graphical tools provided to rescue a broken system, and to use a web browser to search for help. Extensive advice is available online for most kinds of problems that might cause your normal system to fail to boot correctly.

On a few systems, you may need to specify a parameter at the <literal>boot:</literal> prompt in order to boot the system.

For example, Linux may not be able to autodetect your hardware, and you may need to explicitly specify its location or type for it to be recognized.

For more information about what boot parameters you can use, press:

boot parameters understood by the install system

Many kernel modules are loaded dynamically by the installer, and parameters for those modules cannot be given on the command line. To be prompted for parameters when modules are loaded, boot in expert mode (see <link linkend="F3"><keycap>F3</keycap></link>).

You can use the following boot parameters at the <literal>boot:</literal> prompt, in combination with the boot method (see <link linkend="F3"><keycap>F3</keycap></link>).

You can use the following boot parameters by pressing F6, in combination with the boot method (see <link linkend="F3"><keycap>F3</keycap></link>).

PARAMETER TO SPECIFY

<userinput>hd=<replaceable>cylinders</replaceable>,<replaceable>heads</replaceable>,<replaceable>sectors</replaceable></userinput>

Protect I/O port regions

Laptops with screen display problems

Use first serial port at 9600 baud

Force use of generic IDE driver

<userinput>all_generic_ide=1</userinput>

Possible (temporary) workarounds for lockups or other hardware failures:

disable buggy APIC interrupt routing

poll for interrupts

<userinput>aic7xxx.aic7xxx=no_reset</userinput> (enabled if non-zero)

Certain DELL machines

This list is incomplete, see the kernel's kernel-parameters.txt file for more.

These parameters control how the installer works.
