Cannot find recovery files

Hello,

I am trying to create a Windows 7 System Repair Disc image on a flash drive. I cannot find any of the recovery files mentioned. I went to Control Panel > Folder Options, and checked Show all folders and Show hidden files, folders and drives. I unchecked Hide protected operating system files. None of the specified recovery files show up in C:, or anywhere else for that matter.

The computer is a Microsoft certified refurbished Dell Optiplex 780.
