== 🧩 Step 6. Verify BIOS boot order ==

Press F10 → System Configuration → Boot Options, and make sure:

* Legacy Boot Order: “Notebook Hard Drive” is first.
* UEFI Boot Order: moved below or disabled.

Save & exit.

After this, your HP EliteBook 8460p should boot straight into Zorin, no EFI partition required.

Would you like me to include a quick check command to confirm GRUB actually installed correctly before rebooting (so you don’t have to re-do steps if it failed silently)?


'''Prompt:'''
It booted properly after Step 1.

'''ChatGPT:'''
That’s excellent news — 🎉

That means Zorin actually installed GRUB correctly despite the EFI warning — the installer’s message was just a false alarm (it detects the HP’s hybrid firmware and assumes EFI is required even in Legacy mode).

So to confirm everything’s solid:

=== ✅ Quick Health Check ===

Open a terminal in your newly booted Zorin system and run:

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

</syntaxhighlight>

These will quietly verify that GRUB is installed to the MBR and rebuild your boot menu.

Then you can confirm boot mode:

<syntaxhighlight lang="bash">
[ -d /sys/firmware/efi ] && echo "UEFI" || echo "Legacy BIOS"

</syntaxhighlight>

It should return:

<pre>
Legacy BIOS

</pre>

If so — your setup is clean and future kernel updates will continue to boot normally.

=== 💡 Optional tune-ups for HP EliteBook 8460p + Zorin: ===

# BIOS Settings: * Keep UEFI Boot Order disabled or last. * Keep Legacy Support enabled. * Disable Secure Boot (if visible).
# Power management tweak (optional): If you notice fan noise or heat: <syntaxhighlight lang="bash"> sudo apt install tlp sudo systemctl enable tlp --now </syntaxhighlight> That optimizes power profiles automatically.

Would you like me to give you a short “restore boot” procedure to keep on hand, in case a future update ever breaks GRUB again?
