Abstract The Master Boot Record (MBR) save/restore BIOS feature saves an image of the MBR to non-volatile random access memory (NVRAM) residing on the Serial Peripheral Interface (SPI), and then restores the MBR to the same location on the HDD. The MBR save/restore feature makes the HDD bootable in the event of data corruption caused by the user, viruses, or any random event. This document describes the MBR save/restore feature for both HP business notebook and desktop environments.

Saving the MBR in notebook and desktop environments This section documents the save/restore process for both notebook and desktop environments and explains the differences between the two processes. An F10 Setup user option enables the MBR save/restore feature on both business notebooks and desktops. Notebooks On notebooks, you can find the “Save/Restore MBR off the system hard drive” option under the BIOS F10 Setup Security tab. This feature saves the MBR image to NVRAM only after validating MBR accuracy.

Critical device error If for some reason the BIOS is unable to save or restore the MBR image to/from NVRAM, it displays this message and these are the steps you’ll need to take: 2001-Master Boot Record save/restore error.  Press any key to enter Setup.  Try to save the MBR again.  If this fails, run DPS Self Test on the boot drive to check for HDD errors. In each case the BIOS takes appropriate action based on user response.
