I purchased an HP Pavilion 1.5 years ago with Vista Home Premium, and would now like the fact that after such a long time to accumulate quite a lot of garbage and the system is slower to start a radical new start. To setup the system. Unfortunately, yes, HP is no disk, which contains the operating system settled. The function to create a recovery disc, has worked for me for unknown reasons never (He begins indeed to describe the disk [whether DVD or CD, try both], however, comes after firing always the error message that there is problems with writing came the data, and the whole will be terminated. Now there are even now but still the option of using the HP Recovery Manager to carry out a system to be in my view, the data from the HDD HP_Recovery [E:] used. So the system including formatting the hard drive is made? Please advice me on this. Thank you.
