Thank you for your advice.

I understand.

Did you get any error messages from aptitude?
No error messages, but some warnings.

Did you test your burned ISO with cheatcode "knoppix testcd"?
Yes I did after my first failure. The output was...

HTML Code:
Checking ./KNOPPIX/KNOPPIX
All files ok.
...followed by...

HTML Code:
INIT:Entering run level:5
root@microknoppix:/#
...but no GUI. The software I removed was LibreOffice, GIMP, Brasero and some other multimedia applications. Nothing that implied network or system use. I will re-trace my steps. Is there some way I can boot from my remastered ISO without having to burn a CD? I am wasting a lot of plastic.

Thanks again.
