if you attempt to either factory reset or refresh a machine with Windows 8, in some situations you may find that the options are missing, or you may be prompted for installation media.
This is a software problem where the recovery storage area is marked as disabled. Normally, installation media should not be required to perform a factory reset or refresh as the files are stored in the recovery area of the hard drive.

Windows Recovery Environment (RE) and system reset configuration Information:
Windows RE status: Disabled
REGAENTC.EXE: Operation Successful
