Hello Ursula,

I don’t know whether the example you sent is what you typeset, but you should pay attention to close each \startchpater by a corresponding \stopchapter. The same remark applies to other \startSOMETHING command, which should have a corresponding \stopSOMETHING.
This is probably not related to the question you are asking, but nevertheless is important in many instances.

Best regards: OK

\startchapter[title={Bildbeschreibung der Cover-Grafik}]
\setupuserpagenumber[numberconversion=numbers]
\startchapter

Hello evrybody!
 
I need in a Toc pagenumberings with romannumrals and numbers. 
 
I have written this one: 
 
\mainlanguage[de]
 
\setupinteraction[state=start] % don't forget this line!
% make chapter, section bookmarks visible when opening document
\placebookmarks[chapter,section,subsection][chapter,section]
\setupinteractionscreen[option=bookmark]\starttext
\setuplist[chapter]
\setuplist[section][width=1em]
\setuplist[subsection][width=1.5em, margin=0.6em]
\setuplist[subject][margin=1.5em]
\setuppagenumbering
\setupcombinedlist[content][list={part,chapter,section,subsection,subsubsection}]

None of the above setups are needed for a minimal example, remove them next time.

\setupuserpagenumbering[conversion=romannumerals]

You’re looking for the \setupuserpagenumber command (but \setuppagenumber would
also work because it’s a synonym for the command) and you have to use the numbercommand
key to change the conversion.

    \setupuserpagenumber[numberconversion=romannumerals]

Wolfgang
