Well if you have ghost.exe with you from Ghost 2003 all you need is to create a bootable disc. I feel Ghost 2003 might give you that option.
In case it doesnt here is the work-around.
Go to
www.bootdisk.com and download the win98SE OEM image from there. Extract the bootable floppy image from the downloaded file. to do so download winrar and unrar the file. It will give an error but will extract the floppy image. Thats what you need.
Now use some burning software which will let you create bootable disc like Nero or magicIso. you can download the trial version from the website.
There just chose the option of creating a bootable CD. Give the floppy image as the path for the bootable image and set the option in emulation as 1.44MB flopy drive.
In the compilation window where you can add the files in the CD, simply add the Ghost.exe.
Burn it and boot from CD. At command prompt type Ghost.exe. There you go. You have bootable Ghost cd.
