When you’re back in Zorin, confirm it’s running in UEFI mode:

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

</syntaxhighlight>

It should return:

<pre>
UEFI mode

</pre>

If you reboot and the BIOS still says “Boot Device Not Found,” then the EFI entry didn’t register — but that’s easy to fix by manually adding it:

<syntaxhighlight lang="bash">
sudo efibootmgr --create --disk /dev/sda --part 2 --label "Zorin" --loader "\EFI\Zorin\grubx64.efi"

</syntaxhighlight>

Then reboot again.

This should get your HP EliteBook 8460p booting normally from the SSD.
Would you like me to include a quick check command to verify your EFI partition is actually FAT32 before rebooting?


'''Prompt:'''
When I try to reinstall GRUB for UEFI mode, I get: "gurb-install: error: failed to get canonical path of '/cow'."

'''ChatGPT:'''
Excellent — that message is actually very common when running grub-install from a Live USB.
It simply means you’re running in the live session’s temporary filesystem (/cow = “copy-on-write”), and you haven’t yet chrooted (entered your real installed system’s environment).

Let’s fix it cleanly — it’s just one extra step.
