Changing motherboard

NavyLCDR · 23 Dec 2021

Your original problem is that you have Windows 10 installed in legacy BIOS mode, which means it is installed on an MBR disk with an active NTFS partition as the system partition the computer boots from. When you disable CSM mode (which is legacy BIOS emulation), your computer shifts to booting in UEFI mode - which is a requirement for secure boot. The majority of computers cannot boot from an NTFS partition in UEFI mode, most computers need a FAT32 partition to boot from in UEFI mode - and, in addition, the system partition must also contain the proper files to boot in UEFI mode, which your original legacy BIOS install of Windows 10 likely does not have.

I don't see a problem with the motherboard. The problem is that your current install of Windows is not compatible with UEFI booting which you are trying to switch to.

Now, that is interesting to know, NavyLCDR, perhaps if I were to reinstall Windows after attempting to setup the BIOS.

That's one way, yes.

I took the SSD out and popped it in the hot swap caddy on this pc and formatted it, just to be sure it wasn't interfering with anything. Put it back and ran the BIOS, and reset it and saved after each change I made especially sure to disable CSM before enabling secure boot. Ialso set the fTPM and ACHI, and after shutting down, the pc is booting the W10 as I post.
Success! Secure boot and fTPM are shown in Sevice Security.
Going back to where everything started, the PC Health check is still saying everything os ok except for the unsurported processor, my Athlon 3000G.

Solve one problem and another creeps in. Today, I tried out the 5.25 to 3.5 external drive caddy, with an SSD in a 2.5 to 3.5 adaptor. It would not hot swap, I was not surprised as I had not noticed anything in the BIOS. But to be sure, I thought I would enter the BIOS to confirm that because hot swap is very useful and even my other A320 board, an Asrock does have HS.
No go, the del key didn't work. The keyboard was in a USB2 slot, and I tried it in the other one and also in USB3, but nothing but booting to Windows. I have also tried a PS2 keyboard with no success. There is no other way into the BIOS except the del key.
So the only possibility is reset by the jumpers or by removing the battery.

You need to turn off Windows Fast Startup. Or hold down the shift key when you click on shutdown in Windows.

Unfortunately, the shift key didn't work despite trying several variations with shutdown and restart. The BIOS is set to boot from the SSD so I tried the W11 DVD from within Windows, only to meet a brick wall, "your processor does not meet W11 specifications". This is particularly annoying as the Athlon 3000G is in the list of approved processors. I could temporarily replace it with the Ryzen 3 3200G from another pc, but that is a lot of bother.

Hi tinmar49

I've managed to load the bios settings without any keyboard intervention, at least in certain instances. Meaning, it works successfully on my primary MSI laptop.

From an elevated Command Prompt, type or copy & paste the following;

Code:

shutdown /f /r /fw /t 00

/f force running applications to close w/o warning
/r restart
/fw causes next boot to go to the firmware user interface UEFI
/t delay time

The above command only works if you are booted in UEFI mode, for information.

Yes, of course it is. Had tinmar49 not already accomplished the task of converting to UEFI?

I skimmed the thread & thought it was recently updated UEFI, if not, please store for future reference and sorry it's not applicable to Legacy boot.

My mistake you are correct. It looks like UEFI was enabled in post #14.
