For more information on where to get CDs, see Section 4.1, “Official Ubuntu CD-ROMs”.
Some installation methods require other images than CD images. Section 4.2.1, “Where to Find Installation Images” explains how to find images on Ubuntu mirrors.
The easiest way is probably to download the (CDROM) image, because the files most people need are there on the image.
The subsections below will give the details about which image(s) you should get for each possible means of installation.
First of all download the image for your architecture and burn it to a CD/DVD.
To boot the CD, you may need to change your BIOS configuration, as explained in Section 3.6.1, “Invoking the BIOS Set-Up Menu”.
It's also possible to install from removable USB storage devices. For example a USB keychain can make a handy Ubuntu install medium that you can take with you anywhere.
The easiest way to prepare your USB memory stick is to download any Ubuntu CD or DVD image that will fit on it, and write the CD image directly to the memory stick. Of course this will destroy anything already on the memory stick. This works because Ubuntu CD images are "isohybrid" images that can boot both from CD and from USB drives.
There are other, more flexible ways to set up a memory stick to use the Ubuntu installer. For details, see Section 4.3, “Preparing Files for USB Memory Stick Booting”.
Some BIOSes can boot USB storage directly, and some cannot. You may need to configure your BIOS to boot from a “removable drive” or even a “USB-ZIP” to get it to boot from the USB device. For helpful hints and details, see Section 5.1.1, “Booting from USB Memory Stick”.
It's also possible to boot the Ubuntu installer completely from the net. The
various methods to netboot depend on your architecture and netboot setup.
The files in netboot/
can be used to netboot the Ubuntu
installer.
The easiest thing to set up is probably PXE netbooting. Untar the
file netboot/pxeboot.tar.gz
into
/srv/tftp
or
wherever is appropriate for your tftp server. Set up your DHCP server to pass
filename pxelinux.0
to clients, and with luck
everything will just work.
For detailed instructions, see Section 4.5, “Preparing Files for TFTP Net Booting”.
It's recommended to download parmfile.ubuntu
and ubuntu.exec
as well, but using ascii mode.
Properly transfered to CMS, the installation files can be booted by just executing the ubuntu.exec
REXX script.
Alternatively you can also execute the steps from the script manually.
