In BIOS (press F10 → System Configuration → Boot Options):

* UEFI Boot Mode → Disabled
* Legacy Boot Order → should list: * Notebook Hard Drive * USB Diskette on Key/USB Hard Disk * USB CD/DVD ROM * Network Adapter
* Move Notebook Hard Drive to the top of that list.
* Save changes (F10 to save, then Enter).

If that’s all correct, the 8460p is now in pure Legacy mode.

===  ===

From the same BIOS menu:

* Go to Storage → Device Configuration
* Check that the hard drive (HDD/SSD) is detected (e.g., “ST500LM000...” or similar). * ❌ If it says “No drive detected”, then the drive cable may be loose — common in this model. 👉 Power off, remove the back cover, reseat the drive firmly, and try again.

If the drive is detected, proceed.

Boot into “Try Zorin OS” again.

Then in the terminal:

<syntaxhighlight lang="bash">
sudo fdisk -l

</syntaxhighlight>

Identify your Zorin partition (e.g. /dev/sda2), and the main disk (e.g. /dev/sda).

Now mount and reinstall GRUB in Legacy mode:

<syntaxhighlight lang="bash">
sudo mount /dev/sda2 /mnt
sudo grub-install --boot-directory=/mnt/boot /dev/sda
sudo update-grub

</syntaxhighlight>

Look for:

<pre>
Installing for i386-pc platform.
Installation finished. No error reported.

</pre>

If you see that, you’re good.

Then:

<syntaxhighlight lang="bash">
sudo reboot

</syntaxhighlight>

Remove the USB right when the HP logo appears.

Try these BIOS settings:

* Under Boot Options, enable “UEFI Hybrid (with CSM)” if it’s available — this sometimes works as a fallback on HP systems.
* Then reorder again so the Notebook Hard Drive is first.

If that fails, you can also explicitly rewrite the Master Boot Record:

<syntaxhighlight lang="bash">
sudo grub-install --recheck --target=i386-pc /dev/sda

</syntaxhighlight>

===  ===

Once you’re booted into Zorin, confirm the BIOS sees GRUB properly:

<syntaxhighlight lang="bash">
sudo grub-install --boot-directory=/boot /dev/sda
sudo update-grub

</syntaxhighlight>

That ensures your MBR stays synced with your system.

Would you like to paste the output of:

<syntaxhighlight lang="bash">
sudo fdisk -l

</syntaxhighlight>

here so I can confirm exactly which partition should have GRUB installed?
That’ll let me tailor the exact commands for your drive setup — sometimes HP recovery or diagnostic partitions sit in front of Zorin and can confuse GRUB’s install target.


'''Prompt:'''
In step 2, I don't see "Storage"

'''ChatGPT:'''
Perfect — thanks for checking carefully. The HP EliteBook 8460p BIOS has a few different layouts depending on version (F.60 through F.67, etc.), and in some, the “Storage” menu is hidden under another heading. Let’s navigate the BIOS precisely for your model.
