M0le started helping me in diagnosing a malware-infected notebook, and we discovered that I cannot access the recovery boot environment, evidently because "BOOTMGR is missing". This thread is to specifically address that issue.
After reading the checklist you linked to, I entered the BIOS, went to Boot Order settings, and moved 'Notebook Hard Drive' to the top of the list; exited saving changes. (EDIT: I had previously changed the boot order so that 'USB flash drive' and 'USB Removable CD-ROM' were above it, when I was initially trying to diagnose the machine.)
After an additional restart from the HP Boot Options menu, I pressed F8 at the POST screen and arrived at the following screen:
Choose Advanced Options for: Windows Setup
(Use the arrow keys to highlight your choice.)
Safe Mode with Networking
Safe Mode with Command Prompt
Enable Boot Logging
Enable low-resolution video (640X480)
Last Known Good Configuration (advanced)
Directory Services Restore Mode
Disable automatic restart on system failure
Disable Driver Signature Enforcement
Start Windows Normally
Description: [varies based on selection]
I'm not sure that this is the options menu you were expecting when you provided your earlier instructions on running the Farbar Recovery Scan Tool; I do not remember if Safe Mode with Command Prompt will go directly to the command prompt, or load the GUI desktop with a command prompt window. In any case, I will leave the machine in its current state (the above screen) until I hear back from you.
