This HOWTO describes one way to do a Netboot install of Ubuntu 8.04 Hardy by booting from files on a hard disk. This installation method does not require burning a CD (or using any other external media, like a USB key), and it does not require you to configure a server on your LAN for PXE booting.
You need to have grub
already installed and bootable in order to use this method. It is therefore suitable for installing Ubuntu over an existing GNU/Linux installation.
Alternatives
If the computer you are installing on does not have network connectivity during installation, consider using the UbuntuHelp:Installation/FromLinux method, which involves retrieving packages from an ISO instead of from the internet at installation time.
Instructions
1. Download the initrd.gz and linux files from the appropriate page for your architecture:
- i386: http://archive.ubuntu.com/ubuntu/dists/hardy/main/installer-i386/current/images/netboot/ubuntu-installer/i386/
- amd64: http://archive.ubuntu.com/ubuntu/dists/hardy/main/installer-amd64/current/images/netboot/ubuntu-installer/amd64/
Save them somewhere that grub can read from. Inside /boot
is a fine place. (These files are quite small, under 10MB for either architecture.)
2. Reboot your computer and press ESC if necessary to enter the grub menu. Now we will get grub to boot from the files you just downloaded.
Press c to get a grub command prompt. Type each of the following lines:
root (hd0,0)
Replace the root partition with the drive and partition on which your /boot
is located. You can look at and copy the root
line of any existing boot menu entry if you are at all unsure what this is.
kernel /boot/path/to/linux
initrd /boot/path/to/initrd.gz
Replace these paths with the actual paths where you saved the files.
boot
Your system should now boot into the Ubuntu installer. Follow the instructions from there.
