There are several ways to ghost laptops.
1) Use norton ghost to create TCP/IP boot disk for the Laptops NIC card. ( for me its a 3COM 3c905x, because I have a dell latitude and docking station )
2) Dump the ghost to another laptop or dump theghost to a dedicated machine. I use an old p2-400 with 30gb drive. That machine also has a network boot disk and stores all my ghost images.
3) make sure the drive you are dumping it too is FAT32 or else ghost will not see it.
Ghost can image an NTFS drive but it needs to dump it to a FAT/FAT32 partition. At least thats true for the version of ghost I have. Norton Ghost 2001.
4) Finally are you able to create a new partition on the existing 10gb drive with something like partition magic? If so you can just ghost from one partition to the other, reboot, dump the image to the network and then reverse the process. This works but is cumbersome and time consuming.
Anyway let us know how you do!
