    OK, if you say so; however, I thought I remembered using it on a Lenovo 2011 legacy laptop. Maybe someone could test it because I think it is just a fancy catch-phrase for "boot into bios."
    and it wouldn't hurt to try it

    As everyone is aware, once it gets past the logo screen on booting, it's too late to try to enter BIOS. What I have found on several machines is if you hold down the shift key while powering up, don't let go, it will pause at the logo screen. If the BIOS is setup to display available F-keys, they should show on the screen....bottom right, usually. Whether they show or not, start tapping the appropriate key quickly, then let go of the shift key. F2 & F6 are also possibilities according to the HP manual I posted here: Can't change computer bios to boot from disc - - Windows 10 Forums

    The "Advanced UEFI settings" option isn't there if Windows was installed in Legacy mode. It's only an option if you install in UEFI mode.

    OK, thanks for that clarification; however, I vaguely remember having a Lenovo laptop, that had an EFI-capable BIOS, that I had done a legacy install on, and I thought that option was available. So, maybe a pure legacy machine does not have that option as you have stated. Thanks again for the clarification.

    Ok, I know for sure its not there for a PC with Legacy BIOS. I'm assuming it won't be there if you install in Legacy mode. It was MIA on my wife's Acer laptop that has UEFI. It came back on a subsequent reinstall though. That laptop is a bit weird though. It's very fussy as to how you create your install media and doesn't show the UEFI option in the boot menu. It just shows Kingstone Data......, but installs in UEFI mode?

    OK, thank you for that confirmation.

    My reference was sort of a mixed configuration. I had to do a legacy installation because, even though the bios was EFI-capable (as recognized by the Windows installer), all the EFI functionality was locked so an EFI install would hang. So, I created a USB installer, then I deleted the two EFI references in it (EFI folder and EFI boot manager) to force a legacy install, and completed the installation.
