The VGA issue is what stopped me from booting from USB as well.

SOlLUTION: Iturn VGA mode off in the bios > advanced > chipset configuration > onboard VGA set to disabled.

You beautiful bastard! I was stuck and your comment got me though. Why doesn't it work with HDMI???? It would have taken me ages to debug this.

Same exact scenario. This is how I got it to work:

1) Downloaded the Win 2022 ISO and the "Ventoy" utility

2) Inserted a blank USB Stick

3) Ran "Ventoy2Disk X64" and created a bootable USB disk

4) Copied the ISO to the USB Stick I created with "Ventoy"

5) Verified all UEFI defaults in the BIOS setup

6) Verified booting from USB first but also F11 at startup and chose USB

7) Booted into "Ventoy" and selected the Win 2022 ISO

8) Windows Setup launched immediately and everything was cool and normal

I agree jumping through hoops like this is terrible and maybe there is an easier solution but after 2 days of messing around this is what got me moving.

Thanks.]]> Wed, 23 Jul 2025 22:34:11 +0000 https://forum.asrock.com/forum_posts.asp?TID=101286&PID=198500&title=b650d4u2l2t-bcm-cannot-boot-from-usb-stick#198500 https://forum.asrock.com/forum_posts.asp?TID=101286&PID=196711&title=b650d4u2l2t-bcm-cannot-boot-from-usb-stick#196711 Author: joru1407

We came across this topic having the same issue.

A few minutes ago I think I found a solution:
You have to connect your monitor with VGA instead of HDMI or DP.

Maybe it's a driver issue between Windows Boot Manager and the AMD GPU. For VGA the board uses the ASPEED Adapter, with VGA everything works fine.]]> Mon, 16 Jun 2025 20:31:10 +0000 https://forum.asrock.com/forum_posts.asp?TID=101286&PID=196711&title=b650d4u2l2t-bcm-cannot-boot-from-usb-stick#196711 https://forum.asrock.com/forum_posts.asp?TID=101286&PID=195848&title=b650d4u2l2t-bcm-cannot-boot-from-usb-stick#195848 Author: UEFN

ASRock support sent alternative BIOS 20.06 versions and I tried those with no luck.
They also asked if the button at the back of the motherboard was stuck in or partially stuck which it wasn't - it was perfect.
So I have literally given up.
Put in another B650 board but from MSI and everything is perfect.
Has to be the board!

Motherboard serial : HBS0XE000340
I am putting this serial into the post because if this board goes back into stock after it gets returned and gets resold - hopefully the new owner will find this.

For anyone else running into the issue this was my setup and process to worth through.
B650D4U-2L2T/BCM + Ryzen 7 7700 + Corsair 2x16GB (CT16G52C42U5.M8G1) + Samsung 990 Pro 1TB NVMe with heatsink.
Board slow to post but once in BIOS does allow BIOS setup but will not boot into any installer.
Fails Windows Server 2022 install almost immediately and no display at all with Windows 11 installer from USB.
All fully working UEFI compatible sticks.
With Server 2022 it freezes at first UEFI loading screen with "Starting Microsoft Windows bootmgr"
With Windows 11 Pro it won't even bring up any screen. Just completely hangs on black screen before anything when booting off USB.
Tried:
1: BIOS Update to 20.07
2: Total BIOS reset with battery out and BIOS reset pins back to factory. At least 10 times.
3: Tried different RAM slots. Tried 1 stick of RAM. Alternate RAM.
4: Tried removing NVMe. Nothing else connected.
5: Re-seated CPU.
6: Swop out with another identical matching CPU and RAM. Don't have alternatives at the moment.
7: Tried different USB sticks. Tried just bootable diagnostics USB sticks. Nothing but all work on other systems.
8: Tried down clocking RAM to 4800
9: Tried turning off CPU features.
10: Tried turning off BMC.
11: Tried a multitude of advanced config settings and full resets back to defaults.
12: Tried legacy mode USB but that actually causes it to not even go past BIOS.
13: Corsair PSU with both CPU power 12v 1 and 2 sockets both powered.
14: Most common hang BIOS debug error is 08 on mainboard.
15: Researched online and have seen a lot of people having issues with this board.]]> Wed, 11 Jun 2025 19:30:06 +0000 https://forum.asrock.com/forum_posts.asp?TID=101286&PID=195848&title=b650d4u2l2t-bcm-cannot-boot-from-usb-stick#195848 https://forum.asrock.com/forum_posts.asp?TID=101286&PID=195814&title=b650d4u2l2t-bcm-cannot-boot-from-usb-stick#195814 Author: UEFN

I have EXACTLY the same issue.
Battled for 48hrs non stop trying everything.
I am an experienced builder and can't figure it out.
Did you solve the issue?
