Z490-I BIOS Boot Order

Is it possible for the BIOS to remember the boot order?

Here is my scenario:

1.  Attach bootable USB drive

2.  Enter BIOS menu

3.  Select bootable USB drive as Boot Option #1

4.  Exit and save (it says I didn't make any changes, weird)

5.  System boots to selected USB drive (even though it says I didn't make changes it still correctly booted to the USB drive)

6.  Shut down system and unplug USB

7.  Turn on PC, boots to internal hard drive as expected.

8.  Shut down system and plug in bootable USB

9.  Turn on PC, boots to internal hard drive.  I set the USB as boot option #1, yet it does not remember that setting.  I would expect it to boot to the USB since I selected that option in step 3 above.

Any time that I want to boot from a USB, I have to enter the BIOS to select the USB.  Is there a way to tell it to always boot from USB if present?  My previous Asus motherboard I would select boot order based on type (CD, USB, hard drive, etc).  This doesn't seem to have a way to tell it to always boot from USB if it's present.

I would like to boot from USB without having to always select it in the BIOS menu.  Thanks!

Other relevant info: this is on latest BIOS version 2701.  The above scenario was the same on original BIOS version and after update.

Hello,

It may be due to how the USB drive is partitioned. Use Rufus to create a Legacy/UEFI hybrid

https://rufus.ie/en/

13900KS / 8000 CAS36 / ROG APEX Z790 / ROG TUF RTX 4090

I did use rufus to create the disk.  It is an external SSD (strix arion) with Windows 11 installed on it.  When I created the disk using Rufus I selected GPT partition scheme and pretty sure I selected UEFI (non-CSM) target system.

I do not think this is the issue though as it detects and boots the SSD fine when I put it as Boot Option #1 or select it in the Boot Override list.  I feel like if the partitioning was off it wouldn't boot it.

The issue is the fact that the BIOS does not remember that I told it to boot from USB first.
