Boot parameters become necessary when the kernel can not properly detect the hardware, usually due to BIOS problems. Often these problems are not addressable from within the BIOS itself. The previous statement is over simplified, but to attempt a more in depth explanation would go beyond the practicality of this page. | Boot parameters become necessary when the kernel can not properly detect the hardware, usually due to BIOS problems.

What is this?
If you have been unable to get past the installation options screen, where you are asked to start or install Ubuntu, you may notice a list of options at the bottom of the page. F6 Other Options is the selection that will allow you to easily edit boot parameters. Boot parameters become necessary when the kernel can not properly detect the hardware, usually due to BIOS problems. Often these problems are not addressable from within the BIOS itself. The previous statement is over simplified, but to attempt a more in depth explanation would go beyond the practicality of this page.

F6 Other Options
By selecting this option, a line of "boot text" will appear across the bottom of the screen, with a cursor at the end of the line. quiet splash-- Can be seen at the end of the line. The user will want to use the backspace key to delete quiet splash--. And replace quiet splash-- with some other commands.

What parameters to use?
Unfortunately, there is no sure fire approach when you have never done this before or are new to Linux in general. There are some very commonly used parameters, however, that can be tried, and will likely work. Some boot problems can be fixed by simply removing the quiet splash-- at the end of the boot options line. If that fails, you may try some of the commonly used options listed below:
- noapic nolapic
- acpi=off
- irqpoll
- lapic pci=routeirq
One of the above combinations will very likely work on a machine that will not boot the live cd to a desktop for installation purposes.
Other Examples
A detailed discussion of Linux Boot Prompt can be found here: http://tldp.org/HOWTO/BootPrompt-HOWTO.html It is not for beginners, but offers insight into the boot prompt.
Parameters worked!
If the boot parameter options worked for you, you will need to make permanent changes in the file /boot/grub/menu.lst after the installation has completed. If you are very new to Ubuntu, seek help on editing this file from the Ubuntu Forums "Absolute Beginners Talk" section: http://ubuntuforums.org/forumdisplay.php?f=326
