Re: Vaio...Vista...HELP needed.
Basically, you put in the recovery CD and boot from it. Just follow the on screen prompts and choose the option that includes a format of the hard drive. If a message comes up and says something like "all your data will be lost" then you know you're on the right track. Be sure to back up all files you wish to keep to an external storage device before doing this (like music files, photos, videos, word documents, etc...).
But I'm trying, Ringo. I'm trying real hard... to be the Shepherd.
