How do I recover my hp pavilion dv 5000 factory settings without arecovery disc.

During the Power on process there will be a notice to press some key (usually F11) to enter Recovery.

Hello,
In my case F11 idn't work, I simply couldn't get access to recovery partition. What finally helped was SuperGrub (just Google it, burn a cd, takes like 2 min). Boot computer from cd and after reading help, u'll find there recovery partition to boot from. Easy and fast.
