[SOLVED] ASROCK B365 Pro4 Motherboard BIOS settings for Win 11 Compatibility

[Dynan3]

I have followed all instructions I can find to Set Secure Boot and enable TPM 2.0 on an ASROCK B365 Pro4 BIOS. All relevant setttings are correct as far as I can tell. ASROCK won't reply (for over a month now).

Still Windows 11 Compatibility check fails.

Sys info:
Windows 10 Pro
Intel i9-9900K processor @ 3.60 GHz
ASROCK B365 Pro 4

In BIOS:
(Security Tab)
Secure Boot ~ Enabled
Secure Boot Customization ~ Standard

(Advanced Tab)
TPM20 ~ Found
Firmware Version ~ 302.12
Security Device Support ~ Enabled
TPM 2.0 UEFI Spec Version ~ TCG_2
Physical Spec Version ~ 1.3

Please let me know if there is any information I can/need to provide to cure this error.

I really don't want to the landfill glut that this Win 11 will cause by having to get another motherboard.

Thanks for your time!

Probably windows installed in legacy mode.

Why are you looking to go with win 11? We still have 3yrs of support, for 10. You might want to check this out if you are set on moving to 11.

Thanks for your quick response.

Which pages from msinfo32 do you need to see (There are 43 pages)

I have linked the first (opening ) page:

I have noted that LEGACY is indicated for BIOS Mode. I don't see any 'Legacy' mode/choice in any BIOS screen.

ALSO the Compatibility Check (pictured below) indicates TPM is active, but the SYSINFO page shows TPM support not usable.

Please let me know what else I need to provide. I sincerely appreciate your time and assistance with this help. At 70 y.o. I am at the bleeding edge of my computer skills 😊

The reason I want to be Win 11 ready is to prevent headaches post 2025...which might be a moot point at my age.

Again, Thanks!

System is installed in legacy mode.
You have to convert it to UEFI compatible system.

1. First prepare windows installation media for situation, if something goes wrong. You'll need 8GB USB flash drive.

2. Then - separate bootloader from OS partition.
Execute from elevated command prompt. Reguar command prompt will give errors in last steps.
If you get any errors, then stop immediately.

diskpart​

list disk​

select disk 3​

(select 447GB disk containing windows OS partition)​

list partition​

select partition 1​

(select 447GB partition)​

shrink desired=500​

create partition primary​

format fs=ntfs quick​

assign letter=S​

active​

exit​

bcdboot C:\windows /s S:​

bootsect /nt60 s: /force​

Show command output.
Reboot your pc and see, if you can load into windows (do not reboot, if there were errors).
If there were any problems after reboot, then this is where you'd have to use previously prepared windows installation media.

3. Next - convert OS drive from MBR to GPT. This is necessary to make OS UEFI compatible.
Use mbr2gpt utility

https://docs.microsoft.com/en-us/windows/deployment/mbr-to-gpt

4. If everything went good, then reboot into BIOS and disable CSM.
Set Windows Boot Manager as first in boot order. May have to turn off secure boot.
Boot into windows.

Your system should be compatible to upgrade to windows 11 now.

Sky,

Thanks for your expertise! I will do this at the earliest opportunity...when a mushroom cloud rising from my desktop won't be a disaster.

I do have multiple images. I will make the USB installation media first, of course.

Q: Why would Win 10 Pro install in legacy mode? (I used default install settings for the initial lobotomy...)

If this is going to be necessary on any significant percentage of computers in the future, I can see the landfills filling up quickly...around 2026...

Thanks again! Tom's comes through again!
