Problem with reinstallation, bootloader

[Riccardo Mottola]

Hi,

since I cannot boot my machine anymore since weeks, even after trying to 
install the previous versions of hurd, gnumach and libc I did not get 
the box to end the boot sequence. Thus, since I reinstalled everything, 
I have all my /home data in a separate partition anyway. Since my CD was 
not properly readable anymore for an install, I downloaded  the first 
debian HURD install CD. It is from 2013.

I used the "text only" install. The pseud-graphical (exactly as the 
rescue mode) sends my monitor (I tried both an LCD and a CRT) to a black 
screen, but with a signal, but not out of sync. Very strange.

Anyway, installation went smooth except two things
1) no network detected (although HURD supports my network card since years)
2) no bootloader installed

the first is a minor problem I hope, once installed it will perhaps 
work, maybe just some modules or drivers where missing ?

The second however is a problem: my reinstalled system is not bootable. 
No particular errors where shown and I tried twice repeating the 
installation step. How may I fix that using the CD?
