Installing OES Server without Boot CD


March 14, 2008 5:10 am





This is tip will help people who need to reinstall OES regularly (OES testers, DSfW testers) and who are fed up with searching for boot cd with team members (which I used to do before).

I took 32 bit OS as an example to show the steps. Please replace i387 with x86_64 for 64 bit OS installation.

Note: The following steps work only on systems with OS running.
  1. Copy the kernel image and installation initrd to some directory on your system ( like /home) from the source server.

    For example: http://Build-server/sles10/i386/ is the source for the 32 bit OS image.

    wget http://<path to OS installation source>/boot/i386/loader/linux  
    wget http://<path to OS installation source>/boot/i386/loader/initrd
  2. After copying the files, configure your grub configuration to boot these images in /boot/grub/menu.lst.

        initrd /boot/initrd-

    If you have stored the images in /home/, host ip is, net mask is, gateway is, name server modify the above entries like below.

    kernel /home/linux vga=0x314 netdevice=eth0 hostip= netmask= gateway= nameserver=  install=http://<path to OS installation source>
        initrd /home/initrd

    Save the file.

  3. Reboot the system. After rebooting it will come up with the installation screen of the OS to be installed. Start installing the OS :).
