After completing her yearly report and preparing it for printing, my colleague is taken aback when the power goes off without warning. The following day, she attempts to boot up the computer, but it refuses. She believes the computer has ceased to function. Is the world really coming to an end? Perhaps it is something entirely else. How can I recover data from a non-booting operating system? Her report is due immediately. Describe the extent to which you are capable of providing technical help.
