  The geometry of the accretion flow in black-hole X-ray binaries in the hard
state, in particular the position of the disc inner edge, has been a subject of
intense debate in recent years. We address this issue by performing a spectral
study of simultaneous observations of Cyg X-1 in the hard state by NuSTAR and
Suzaku. The same data were analysed before, and modelled by a lamppost
containing hybrid electrons and located very close to the horizon, which
emission was incident on a surrounding disc extending almost to the innermost
stable circular orbit. We re-analyse the incident continuum model and show that
it suffers from the lack of physical self-consistency. Still, the good fit to
the data provided by this model indicates that the real continuum has a similar
shape. We find it features a strong soft X-ray excess below a few keV, which we
model as a soft thermal-Comptonization component, in addition to the main hard
thermal-Compton component. This continuum model with reflection of both
components yields the overall lowest $\chi^2$ and has a geometry with a hot
inner accretion flow and a disc truncated at $\simeq$13--20 gravitational
radii. On the other hand, we have also found spectral solution with a lamppost
at a large height and a disc that can extend to the innnermost stable circular
orbit, though somewhat statistically worse. Overall, we find the fitted
truncation radius depends on the assumed continuum and geometry.
