The problem is basically that if you format and change your notebook OS, when you want to restore the original system (factory), notice that the famous F11 keystroke activates the recovery does not work. We must take into account that the files are in a hidden recovery partition on your hard drive and they should not be changed for any reason; and said partition must not be altered; garantizaras only then that the recovery work. If for some reason you modified the partition or recovery files no longer you keep reading and better looking for an extra source of income to pay for recovery discs that PEDIRAS to HP.
The method mentioned forum is applied from Windows XP; I took a chance and did the test from Windows Vista and ... !!! Congratulations Funcionooo¡¡¡.
Without further ado, the Method:
1. From your xp system (if you have installed the xp): Start> Run> compmgmt.msc
2. Then go to Disk Management
3. Find the recovery partition (commonly D)
4. Right click on and mark it as active partition
Reboot, does not operate F11, dale in boot options and select notebook
Thanks ... I hope its A and the orientation of Users most advanced ...
