That morning I'm happy!
You are a very good teacher. All you've write, I've tried before. I've tried repair starting; after 1 hour i stopped. then I had 4 lines of restore point; For each one I waited 1 hour without result, before ach time the computer says impossible to restore, il seems that antivirus don't let the restore be fine! put off the antivirus; how to do. So I go out and restart; the screen was black. I let it and go to sleep. But at 3 o'clock, I came to see and the computer was unlight. I start and miraculous, windows made his work; I find it runing. I think that I was too much hurry. The start repair must take more than 4 or 5 hours. However the computer has repaired by himself. Conclusion: with the computer who run so fast, we lost very much time, and we are alwals too hurry.
Being in my summer house on the riviera, it's the first time I don't take with me my external Hard disk where are writen all secure backups.
Thank you for your help. I hope I don't need it again
