preseeded installing hangs before boot loader install

[Tiago Alves <alvesfonseca@ibest.com.br>]

Hi folks,

I have a version of a cd which is able to install debian (when
connected to internet) and I am using preseeding to automate some
steps.

The point is, I can't proceed the install process just before the
bootloader installation: after installing all the requested packages,
the debian installer hangs asking for the 1st cd, which is on the
cdrom drive and mounted, however the system is not able to recognize
it. The workaround I am using to finish the installing is to press
"ESC" and to manually finish the install process by choosing the
remaining steps via debian installer menu.

Is there any way to avoid this workaround?

I am using build-simple-cdd and I turned off the security updates and
also the mirror setup (as I want to provide packages through a cd) by
preseeding.

Thanks in advance,
Tiago
