(What disks are those? Debian fits on a single DVD.
Where did these disks originate?):
The disk came from OSdisk.com. Ten 64bit DVDs. Disk one does have a complete Debian OS which has been installed.
(Normally you would install a program from the extra disks, not import(?) them all.):
I installed the complete Debain OS from Disk one. "Import" may not have been the correct term. I want to add the packages from Disks two - ten.
(The disks should be listed in /etc/apt/sources.list, I believe):
Packages from the remaining Disks were not transferred to the system. This sources file has only comments (#).
(Edit: When you try to install a program, apt will tell you which disk to insert.):
Correct, but after the complete Debian OS was installed, further input was then stopped without a dual boot. There are thousands of packages in the other nine disks.
Attempt to de-confuse:
I have installed Debian OS (from OSDisk.com) as the only OS on computers several times, then a dual boot was not required. In those installs I did not terminate the install and completed installing the packages from the remaining disk. This last install required a dual boot on an Acer with MS8.1. I installed the Debian OS without a dual boot.
It was 3 months before I found some one that could install a dual boot. The dual boot was installed 3 months after the Debian OS. Until the dual boot was installed I could not get to the Debian system. That left me 9 Disks to add to the sources list. BOTTOM LINE: I have a fully functioning Debian OS and I want to add the packages from the remaining Disk i.e. Disks two - ten.
