installed Windows 10 on my laptop. Installation went OK but then problems. Wifi was randomly getting turned off, Skype click to call was disabled as was Avast online security. On checking these extensions there was no button present to re-enable.just a message saying disabled (with 8.1 I never had these problems). I decided I would restore to earlier time ie to the date of 10 installation and try to see what had changed to create the problems.Two restore points were offered so I chose the first. Laptop closed down properly but on restart the sequence gets as far as computer starting up but then all I get is the mouse pointer and loading circle just going round and round, boot does not continue beyond this. I have been into setup (F2) and tried booting from HDDO, same result. I did not make a recovery disk (much regret) as I have never had a problem with other Windows versions on the few times I have needed to restore so did not expect this and also my understanding of the blurb with Windows 10 says this should not happen as system is failsafe. I have tried recovery with EasyRE repair disk in CD drive but it is not recognised. The laptop is a Packard Bell Easynote TE. Does anyone have a solution preferably one where I will not lose all my files on the drive?
