I'm trying to ghost an image of my ubuntu 8.10, but I keep getting an error

File Name ? (546)
Output error file to the following location:
A:\ghosterr.txt

I then put in a blank floppy that it can write the error code to it, click ok and then I get the error

Usage Error 662
Cannot create image file Z:\Kiosk\ubuntu.gho
Dos error: access denied (0x0005)

I click ok and it boots me out of ghost.

I don't want to use anything else. I want to use ghost because where I work we ghost everything and I don't want to have two different ways of doing things. I do have another location that I could go to that does have the lastest Ghost suite, would that work better?
