If you are trying to locate the Preboot Menu on HP Printers, I have some information to get you there from troubleshooting Compaq and HP hardware over the years for businesses, colleges, and universities.
Partitions on a Printer’s Storage:
* PREBOOT
* CEKERNEL
* Core
* Machine
* DataModel1
* DataModel2
* CtbData
* Interrupt
* Customer
* Extensible
Before You Proceed (Optional)
If the printer is configured to be used by numerous devices or people (such as in an office environment), be considerate and let those other users know that print access will not be available for a few minutes so that they can make the choice of either waiting for the repairs to complete or choose to send their print jobs to another printer as this will help you save on wasted ink and paper. I would go a step further and disconnect any data cables (ie. Ethernet, USB) so users who have a memory relapse of your request won’t send print jobs through until your task is complete. If you are female or have very long fingernails, I encourage you to have a stylus handy.
After Your Task (Optional)
After you have finished your task in the Preboot menu, take the time to look over the printer. Are the vents clean and clear? If dust is building up, it can lead to internal parts failing faster than normal thus producing frequent paper jams errors.
Note: Multiple options represents models with and without the touchscreen.
