[ltp] A corrupted or missing Windows config on my A21P

[Constant Brouerius van Nidek]

On my A21P I am running Linux as my main OS (Opensuse 10.2 and 10.3) with the 
first 10GB partition Windows XP. It is my first experience with Windows.
Somehow booting Windows I now get the information that I have a corrupted or 
missing Windows config. (windows\system31\config\system) No problem because 
there seems to be a repair possibility. I booted the CD, pressed R in order 
to do the repair and do not see any automatic repair activity. It finds the 
C:\Windows and after entering help I get a lot of possibilities for whatever 
action in what they seem to call "recovery console", but nothing telling me 
how to restore the config. 
I am more versed in Linux and this excursion in Microsoft-land comes after my 
90's  experiences with Windows 3.1 and 3.11. Am still fix with Dos but 
repairing this OS is out of my reach. Even simple things like chkdsk and dir 
give unclear answers if any. Could somebody help me? Is a reinstall the 
better way?
