Hello. I need to reformat my computer. It's a long story but I have had recurring issues with malware and I have been advised that the best option would be to reformat the laptop. What I want to know is, what is the best way to do this? I understand that there is a hidden recovery image on my hard drive. For this reason I have gone through the advanced start up option to do this but I get an error that the recovery image cannot be found. P.S I am running windows 8. My second question is in relation to the Toshiba recovery wizard. This is another option on the advanced start up menu. If I select this process will I need to reinstall the operating system? This would prove problematic as the software came pre installed on this laptop. I have looked at the user manual for this particular model and the consequential effect is not made clear in relation to Windows 8.
