Hi Dan,
The way to change the location of the error file is to run Ghost.exe with the switch -afile.
For example, if you want to write the error file to d:\path\ghosterr.txt, start ghost with the following command line.
ghost.exe -afile=d:\path\ghosterr.txt
Seeing as your machine doesn't have a floppy drive, you will need specify a destination that is on
1. A FAT/FAT32 partition on the harddisk
2. A FAT/FAT32 formatted USB key if your machine can detect it under DOS.
3. Mapped Network Drive.
Can you then paste the content of the error file into a post so we can see why you are getting this error.
Cheers
Peter
