Nitro N50-640 not booting, says 'Reboot and Select proper Boot Device or insert Boot media'

I am getting the message 'Reboot and Select proper Boot Device or insert Boot media in selected device and press a key message' when i turn my PC on. I have a Windows Boot installation USB that Microsoft configured, but my PC isn't recognizing it. Can anyone help?

The PC isn't recognising the flash drive the Microsoft Tech support created

Is there a BIOS flash or similar I can build on a USB?

You need to get from the the Nitro N50-640 desktops Acer drivers page, the IRST (Intel® Rapid Storage Technology) Driver version 19.2.0.1003 folder and put this folder into the Win-11 bootable installation USB.

Construct the bootable USB with Rufus 4.9 and follow its guide, as this works 100% as bootable installation USB for Win-11 version 24H2, so use that.

When you get to the installation section below at > Where do you want to install Windows? > Load driver > install the IRST driver Managed Controller 09AB driver > as afterwards the N50-640 desktops boot M.2 SSD drive will be recognized and you will be able to continue the Win-11 clen install and finish the installation, as that is where you are going wrong and you can't install Win-11. It’s a very simple process, good luck.

Load the IRST driver Managed Controller 09AB at this part of the Win-11 installation stage below:

Hello StevenGen,

Unfortunately, it isn't picking up the flash drive with the RST (Intel® Rapid Storage Technology) Driver version 19.2.0.1003 folder and returns the 'Reboot and Select proper Boot Device or insert Boot media in selected device and press a key' message.
