I have: pavilion dm4 2033cl
I turn it on and observe this:
Step 1: Message "Press The ESC Key for Startup Menu" is printed at the very bottom left of an otherwisely blank (black) screen. Then the computer power-cycles -- the screen goes blacker (LCD goes off) for a good second. And then the cycle repeats from step 1 indefinitely.
When I press ESC, I am presented with the following screen:
F1 System Information
F2 System Diagnostics
F9 Boot Device Options
F10 BIOS Setup
F11 Sytem Recovery
ENTER - Continue Startup
For more information, please visit: www.hp.com\go\techcenter\startup
Running F2 - Start-Up Tests reports:
Memory Test: Passed
SMART CHECK: Passed
Short DST: PASSED
Optimized DST: PASSED
Battery Test: Primary - PASSED (0)
PCI Device Check: PASSED
Nevertheless, the laptop keeps on cycling like in Step 1.
What do you think can be the issue? What are some next steps I can try? Have you seen this before?

Turns out I can boot from a DVD.
But ... I cannot access RECOVERY or HP_TOOLS or any other partitions apparently. ..
What can I do?
--- Hang on a second..
I've inserted my own Windows 7 64 Bit disk and chose UPGRADE option, which told me "Remove DVD, and boot into OS first to use UPGRADE option".
I did, and lo and behold everything started splendidly.
I guess Windows 7 64 Boot Disk experience graciously rewrote the MBR, or whatever was causing the machine to cycle endlessly.
