Transferring FSM from One Computer to Another

You may have to configure the external drive in order to upload onto it.

Once you do that it should download onto the new computer without problem.

ask the internet, referring to your external drive type.

Another option, which I now rely on more, is to use a cloud server. 

Or just purchase a USB ROM drive. They're relatively inexpensive, and you might need it again in future.

If you have access to the original cds and can copy from your notebook to your new machine, look for the .iso file on the cdrom.  Copy to your new machine.   Windows 8 and 10 have native virtual  cdrom mounting  (of the .iso file).  Otherwise there are free tools available for older versions of the OS.  I like virtual clonedrive.
