Asus Zenbook only boots to bios after win11 update

[Jasonrusso]

I have a Zenbook Pro UX501VW-US71. Everything was working perfectly fine until tonight. It's running Windows 11. I had a Windows update tonight, which I installed.  After the reboot, the PC only boots into the bios.  It goes into the bios real quick.

If I go into the NVMe setting, it sees my hard drive.   I made an Acronis boot drive (I have an identical PC, the problem one is my wife's) and a windows 11 media creation tool. 

Both are recognized, because I can make a boot path to them.  The PC will not boot from either of them.  It is like it doesn't try. It's too fast to try the USB and fail. 

I tuned off secure boot, turned on CSM, legacy boot, etc. 

Tomorrow I'm planning to remove the battery and CMOS battery to reset the MOBO.

This issue may have been caused by a corrupted EFI Boot Entry after a Windows update. We recommend first disabling Fast Boot in the BIOS, ensuring that you are booting in UEFI mode, and then using a Windows 11 installation USB to enter the recovery environment and perform a startup repair. Thank you.

I don't think you understand. My laptop doesn't have Uefi, it only has legacy. 

I made a Win 11 flash drive, but it doesn't even attempt to boot from it. I set a boot location to the efi file on the usb and it doesn't work. 

I downloaded the bios file (307) and tried to reinstall it from the ez flash in the bios, but it says the "file is too old" because it is the same version

Sorry, I have confirmed that this model is an earlier version. 
If the issue cannot be resolved, it is recommend backing up your important data first, then restoring the BIOS to its default settings and reinstalling the system. Sorry for any inconvenience it may be caused.

I tried reinstalling the BIOS, but I cannot because I have the current version.  The PC says that I need a later date of BIOS.  Is there another way? 

I confirmed that the SSD is good. I put in in an enclosure and I can access all the files.  I even installed an old SSD and it won't boot from that one either.  

I have a replacement motherboard on order. I feel like that is the issue.
