I was attempting to Update my bios last night because I am running a X470 motherboard with a 2700X and I just bought a 5700x3D to upgrade, and I needed to update the bios to support the new chip.

I downloaded driver update 6223 for my asus rog strix x470-f gaming motherboard from the asus website, put it on a flash drive, renamed the file with the file renamer. Attempted to update the bios. At the end of it I had a screen that said

"Bios update failed
Security verification failed"

with a complete system freeze. eventually forcing me to hard reset the pc by holding the power button.

Apon reboot (I think it took a few tries) It DID boot into some sort of bios repair, and to my surprise, it DID boot into the bios, The bios screen says the new bios number and date (6223) and the bios itself seems to be functioning.

I can't boot into windows... That is my issue and why I am here. I tried, and tried, over and over. The Rog logo appears (instead of the windows logo, standard for this board.) And I get the spinning dots.. perpetually. Sometimes it will attempt start up repair, most of the time still spinning perpetually. One time I got to the windows repair screen but it gave me no meaningful options for a solution.

I have tried fiddling with what mode the drives are in UEFI, ACHI, Raid, ect. And secure boot, from reading other posts I have seen recommending to do so, but I was just messing with settings in vain.

The previous bios update changelog on the website before the one I used warns about bitlocker. To my knowledge, I did not set up or use it ever.

please help.

Asus Rog X470-F gaming
Ryzen 7 2700x (Wraith cooler)
Corsair 3000mhz 32gb (4x8gb)
500 gb samsung 870 evo (boot drive)
500 gb samsung 870 evo (storage)
5tb (seagate I think) Hard drive (storage)
Asus Strix Gtx 1080
Thermaltake 750w psu
Windows 10

Edit: I THINK that I had updated my bios once before when I got the system in 2019. I am not even entirely sure if I did or what version I grabbed. It was a long time ago. I don't know how relevant that is, but I wish I had taken note of the bios I was updating from.

did you see any of the storage in bios?
could either try update the bios again.
and remove all the non-boot storage
All 3 drives appear in the bios. I have tried booting with a boot overide. The boot drive which is in the correct spot in the boot order will spin the windows dots perpetually. The other SSD simply asked for an OS.

I am at work currently, but I will try any and all suggestions when I get home.

Did you set CSM/UEFI accordingly to which mode windows were installed ?

You can't mess with those settings in random.
You have to know, what you're doing and what settings are appropriate.

BIOS update can change default values for those settings.
You have to restore them to previous values (before BIOS update).

I'd suspect, you had windows installed in legacy mode.
After BIOS update, UEFI is made as default boot mode.
That's why, you can't boot into windows anymore.

Option #1 - if windows was installed in legacy mode:
CSM - enabled,
Sata controloler - AHCI mode.
First boot device - SSD in legacy boot mode (not UEFI)

Option #2 - if windows was installed in UEFI mode:
CSM disabled,
Secure boot - keep disabled, you can enable it later,
SATA controller - AHCI,
First boot device - Windows Boot Manager on SSD (UEFI mode).
