Gateway netbook LT28 restore from nowhere

According to my client, this netbook was interrupted by power cord disconnected,
then its never back to normal.

How do I restore my computer using the eRecovery Management program?


None of these worked out for me.
It doesnt seem yo have recovery partition by itself, there comes ghost recovery option along with windows 7 normal mode, this option failed to click into recovery mode either.
With attached USB external CDROM drive, and generic WIN 7 home premium disk, select windows repairs, it all clear out the problems.
