I have a SONY VIAO PC that is running Windows 7 which has a current version of Norton 360 installed. The PC was running fine until yesterday when Windows would not start. Pirior to this activity, in response to a pop up on FB, a JAVA update (?) was supposedly installed. Once the PC was restarted the problems began. I cannot run either NPE or the Bootable Recoyery tool either from the internal DVD or USB device. Any suggestions on how I may be able to recover without loosing the data on the PC?
