Windows 10 install problems on HP 8300

I had a previous post about creating a Windows 10 flash drive for install. That was solved.
Possible to install Windows 10 without Windows 10 PC?

However on five tries to install, the install screen keeps coming back. I've tried with and without entering the activation key. I've tried with no partitions on the hard drive and with a partition on the hard drive.

HP Compaq Elite 8300 USDT
8 GB RAM
500 GB HD
Optical DVD Drive
Processor Intel(R) Core(TM) i5-3470S CPU @ 2.90GH
8300 bios supports UEFI and legacy boot.

I'll try again, but it is perplexing.

Hello cootcraig and welcome to TF ,
Do you have Windows currently installed on this drive and bootable/login-able or not?

When the installation restarts don't press any keyboard key if you do you will restart installation so don't.

Just remove the installation drive (USB or DVD) and start the computer.

It's at the location entry screen.

When to remove the USB flash drive?

What happens if you remove the USB now and reboot?

When you installed, did you remove everything external other than necessary keyboard, mouse, monitor?

How did you make the install media? MS website using MCT is recommended.

Figured it out. I changed the boot order to hard drive first. Silly me, I forgot I had set to USB first.

Did not have any Windows PC. Used WoeUSB on Linux.
