  The Recovery partition "Dell PC Restore" will delete any user data when it restores the PC to the original factory condition.  There is a procedure in Windows 7 to create a System Recovery Disc and that would allow you to repair Windows if needed.  Otherwise you must have the Windows 7 disc to do this, or reinstall.    You will have to contact Dell for your area to obtain the needed disc(s).   Also, there is a Dell Data Safe application, where you can make yourself a set of Win 7 64bit OS disc's. In the event that the F8 command does not work, then you can use the disc's you made with Dell Data safe to get your system back to factory state.  See HERE.
I have recently bought an Inspiron n5010 having Windows 7 home premium 64 bit installed. For some reason i have to reinstall my os. But, i did not get any cd or dvd of the os. But, there is a recovery partition. Is it possible to reinstall only the os(without harming data on other partitions) from the recovery partition and how can i do that? If not, what can i do to reinstall my os?   Thank You very much.
Windows 7 reinstall
