I recently installed the media creation tool at the Microsoft website. Before doing this, I formatted the USB to FAT32. I plugged in the USB to every port including the Mobo and front ports. It does not appear in the boot options when I get into bios. I am basically stuck since I can't install the OS to my newly built pc.

Mobo: Asrock B450m Pro4

my wife has this very same motherboard

it should just automatically boot from the usb when it dosnt see an o/s on hdd

reset bios to defaults
place a formatted hdd/sdd in sata or nvme and switch it on
the default bios settings should look for hdd and then go to usb drive

i would also retry to make the usb drive with a fresh copy of windows media creation (it might have corrupt bootable files)

I just reset the bios to defaults. I also did a new windows creation tool as well. Formatted it the usb the same way (fat32). Turned on my pc and it didn't boot automatically. Checked in bios and only my nvme m.2 ssd shows up. Its the only boot option appear. Not sure what I did wrong

Press F11 while booting and start the USB stick as "UEFI", then it works

I tried hitting f11 when turning on the pc. There is no option to to start the usb as UEFI because it does not appear there. All I see is "Please select boot device NVME:...." "Enter setup" "Boot Default"
