起動すると「American Megatrends」の画面で停止して起動しない．

[Itsuo]

購入後，WSL2(Linux sub system)/Ubuntu をインストールしたが，インストール直後の再起動でブートしなくなりました．

電源　OFF/ONで起動しようとすると，BIOS 「American Megatrends」と表示した画面で停止したままになります．
再び　OFF/ONでBIOS設定画面を表示するため　ESC，DELキーを押しながら起動しても同じ症状です．

対処法はあるのでしょうか？

The symptoms you describe sound like a problem booting into Windows. Does it go into the BIOS area and let you view settings? Are you able to find the storage for the system? Verify it can see the storage device. Also, see if you can boot from a Windows USB drive.

Have the same issue, installed ubuntu to check the systems and then tried to install windows 11.

I see the hard drive, formated it several times and even tried a different hard drive. both work fine in all other systems.
I can use the USB installer to install Windows - bios stuck after the reboot tho.

I can enter bios setup, i checked the bootorder, disabled and enabled secure boot.
Disabled all registered boot-keys.
when override boot from the drive, windows repair shows up. don't work sadly.

I don't want to use any drivers, OS or other downloads from the factory or vendor, since they are all virus infested.
Probably would try to flash bios, since there isn't much the producer can mess up there.

All I see is the "American Megatrends" Logo with a boot circle, which gets stuck after about 3min.
Nothing else to see, not even "press del to enter setup" or anything.

First, you need to restore the BIOS settings. Next, you can refer to the following guide for installing the Windows system and use the system files below to install Windows 11:

Try disabling NX mode in BIOS under the CPU settings, this worked for me.

I have the same exact issue with AM06PRO and 5825U Ryzen CPU.
Disabling NX mode equally creates problems with virtualization and also disables a security feature.

Has anyone found an updated firmware ?
