Hello,

The method that I explain a message before didn't work. I have tried from usb and with a boteable cdrom,

but they did not work as I thought or maybe there are mistakes with the steps which I have followed.

I am a bit lost, because It is a new situation to me, it never had had a similar situation before.

Please, If you know the solution, or if you know that this kind of problem have no solution only by software,

write about it to me.

While I will continue looking for.

Thank you very much and the best wishes.
