Hi Andrey,pro,

finally after having manually replaced quite a number of files from original Vista Home Premium recovery DVD as well as from SP1 and SP2 I finally regained access to my PC through a normal boot. (Files replaced where those indicated by CBS.log output from sfc /scannow command)

Eureka !

Now, I find myself without avast (I’m led to believe that the first fixlist.txt removed it) and I would like to reinstall it before microsoft pushes me to install “Essentials”.

May I proceed to reinstall avast normally or I have before to make some thorough cleaning of previous installation remnants ?

Also, at the end of the process I’ve still no idea of what may have been the reason for the impossibility to boot.

Do you have any possible reason for what has happened, so that I can prevent further occurrances of such a situation ?

Thanks in any case for your support and indications
