HP Elitebook 8570w custom boot logo

Solution 1:

I'm not sure how you will enter the custom logo, but I can help you to make the HP recovery partition visible

1. Press key, type cmd in the Search field and press Ctrl + Shift + Enter
2. Type diskpart in Command prompt
3. Type list disk
4. Select the disk (In my case i have only one HDD and it is disk 0)
5. Type select disk 0 (number 0 is valid in my case, in your case it could be different)
6. Type list partition. It will list all partitions for selected disk (0 in my case and my recovery partition is Partition 4)
7. Type select partition 4 (enter your partition number instead of 4)
8. Type assign (and press Enter of course :)

And your partition is now visible !!

How to get the boot logo working (how I did it):

• Verify that you have a HP_TOOLS partition, see NikolaD's answer how to do so.
• If not, use the following install program to create the partition (sp60844.exe) http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdDetails/?swItem=ob-116962-1&ac.admitted=1381442205113.876444892.492883150
• Another way (not verified myself) is to create the partition yourself. It should be called 'HP_TOOLS' without the quotes, 2 gigabytes and formatted as FAT32.
• The logo should be at most 1024x768 pixels, jpg format, at most 32 kilobytes in size.
• Save the boot-logo to HP_TOOLS/Hewlett-Packard/Logo/Hplogo.jpg - where HP_TOOLS is the root of the HP_TOOLS partition.
• Reboot the laptop, go to the BIOS via F12 → System Configuration → Custom Logo → Enabled (might be blocked by other BIOS settings) → Save and exit.
• Reboot and you will see your custom boot logo.

This works for my HP Elitebook 8570w, but I cannot guarantee it will work for every Elitebook.
