hello
i have cleaned a HD with V3.09.1493, 2 days ago. i asked a cleaning of Windows System and cleaning of registry .Ccleaner found 160 errors of registry to correct.
when i rebooted after correction i obtained the following message: " 1962 : no operating system found.press F1 to repeat bootsequence"
when i pressed F1 ,there was no answer.
after several trials, Windows started. and now it works apparently well.
can i leave the system in this state, or must i restore the old registry ?
