I am using 6.2. I downloaded Knoppix and installed it to an 8GB USB drive.
It asks during boot for the size of the overlay file (300MB to 4000MB). I enter 3000MB, and do OK, and it does not ask me anything about encryption, it just boots. I have a very fast system, so maybe there is some kind of timing issue?
Here are the instructions I used to install the flash drive:

I solved my problem. I think that the documentation is a bit weak in this area.
Since the "personal file" choice said between 300MB to 4000MB, I thought I should enter something like 3000MB. I even tried 3GB.
This is incorrect. It wants only the integer.
Am I completely alone in thinking that it wanted the "MB"? Otherwise I think they should make this clear somewhere. I have not seen any screenshots or examples of what to enter for the response for the "personal file" during boot.
I can't figure out how to enter a bug report on 6.2. Bug reports seem to stop at 5.3:

Here is what I could find on customization:

Do I add something of my own to the custmization wiki?
Glad to know your problem is solved.
It's a Wiki, JohnKlug, go right ahead, register, update away and make it more useful for othersDo I add something of my own to the custmization wiki?![]()
I updated the customization FAQ, specifying that the size must be an integer:
