Lots of 'depends' here.
What version have you got ? Certainly 2003 works on linux partitions, but I am not sure about earlier versions.
Where are you going to ghost the image too ? Do you have a spare drive in the machine to ghost to ? If you have a second drive in the machine, why not just install the server with mirrored drives ?
For a straight ghost from one disk to another, you need a plain DOS boot disk with a copy of ghost.exe on it and boot from that. If you install Ghost 2003 for Windows on a client machine, there is a utility to create a DOS boot disk with ghost on it. You can then reboot your server with the floppy and ghost your drive.
If you want to do it over a network then you will need some dos network drivers to get the machine on the LAN.
There is plenty of documentation with Ghost.
Good luck.
