But Now I notice that I can't apply this XP ghost in Toshiba or IBM PCs. How can I do this?
You cannot do this.
Reasons:
1. Not possible: PCs must be identical.
2. Mot legal: Windows licence does not allow.
Mean to say I want to apply it to all PCs? Many times when I apply this Ghost file in another the Windows will Restart or make blue error at loading.
That is expected. Windows installed on Dell, not work if copied to Toshiba. No can do.
Solution:
For each machine, pay for Windows licence, install fresh.
