Once booted:

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

</syntaxhighlight>

* You should see /dev/sda with a single Linux partition and a bootable flag on MBR.

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

</syntaxhighlight>

* It should print Legacy mode, confirming everything is aligned with BIOS.

✅ Advantages of this method:

* Works reliably on HP 8460p — avoids all UEFI/EFI quirks.
* Simple, fewer steps than trying to force a UEFI install.
* GRUB installs directly to MBR, so no firmware boot entries are needed.

If you want, I can write a visual “partition map” and exact commands for the Legacy install, so you can recreate /dev/sda partitions quickly and safely without guessing.

Do you want me to do that?


'''Prompt:'''
Reinstalling in Legacy Mode, I do not see "Reformat the SDD" after Something Else

'''ChatGPT:'''
Perfect question — that’s exactly the right place to pause. The Zorin (and Ubuntu-based) installer doesn’t have a button literally labeled “Reformat SSD” — instead, you “reformat” by deleting all existing partitions in the manual partitioner under “Something Else.”
