Boot from Hard disk drive

How to add option to boot from hard disk drive

Have you tested F4 to boot from the local disk and then option "Search and boot Windows".
It worked well here, Windows 10 x64

I've tried F4, but I went with "Boot the 1st local disk" to boot a drive with Grub2 and a variety of Linux distros on it. F4 does seem like what I'm looking for, but I just get a black screen with a blinking cursor. Have to hit the power switch.

There's only one hard drive and the thumb drive with Ventoy on it.

Anybody else experienced this? Any idea where I'm going wrong?

Even with this little challenge, Ventoy is the best thing since sliced bread.
