Please see "Creating Recovery Discs or Saving a Recovery Image to a USB Flash Drive (Windows 7)" for instruction on creating a set of recovery discs or USB flash media. Please continue the process of trying to create a set of discs... if it states that a set of recovery discs has already been created, you will not be able to create another set and may have to order a set.
Please see "Performing an HP System Recovery (Windows 7)" for instructions on performing a recovery from within Windows 7, from the startup screen (during system boot), or from recovery discs. Provided the recovery partition is still active and undamaged, you should be able to recover the computer using one of these methods.
