Question Upgrading to Windows 11 - Secure Boot Issue

[pkilway]

Currently have Windows 10 Pro, I'm eligible to upgrade to Windows 11 - BUT the Windows Upgrade tool is telling me that I don't currently meet the Windows 11 system requirements.

I built this system in December 2021, and have been getting this error since then, but haven't done anything about it until now.

System:
PSU: EVGA 710 BP, 80+ BRONZE 700W
MOBO: ASRock B550M STEEL LEGEND AM4 AMD (Bios Ver: 3.20)
CPU: AMD Ryzen 5 5600G (Cezanne)
RAM: CORSAIR Vengeance LPX 32GB (2 x 16GB) DDR4 3200
M.2_1: Seagate Firecuda SSD 520 1TB Gen4 X4 NVMe 1.3 (OS Boot Drive)
M.2_2: Seagate FireCuda SSD 510 500GB Gen3 x4 NVMe 1.3
M.2_3: WiFi Card 6E (Gig+) AX210
SATA_1: LG Electronics 14X SATA Blu-ray
SATA_2: Seagate BarraCuda 2TB Drive 7200PRM HDD
Misc: Pomya Internal Card Reader Dashboard (B07SC1W9V2)
PCIE1: ASRock AMD Radeon??RX 6600 Challenger D 8GB RX6600 CLD 8G
OS: Windows 10 Pro 64 (all updates in stalled)

Says I need to enable 'Secure Boot' in the BIOS, but when I do - my M.2 OS Boot Drive disappears and it enters an endless loop going into BIOS due to a missing OS drive until I disable Secure Boot. I will provide any and all photos of the BIOS to help diagnose this problem, just tell me where to start.

Just cuz the boot drive disappears doesn't mean it's actually not being recognized. I literally did a W10 reinstall but before doing it couldn't see the main drive I wanted it to install to but already knew it would be noticed at the install process so..................if any chance just fresh install W11 instead and it might recognize it during it. Either that or just see if your running on UEFI booting via W10 if your upgrading from that as it will confuse it for something else. Upgrading these days to W11 has been hectic as it's a hassle to even get the drive to be shown so...................food for thought.............

Thanks for the input. I don't have a fresh copy of W11, I purchased W10 Pro - but was eligible for the free upgrade. Figured I give it a shot, but was running into this issue.

Most likely - your system is installed in legacy mode and it's necessary to convert it to UEFI compatible.
This can be done with mbr2gpt utility.

MBR2GPT

Use MBR2GPT.EXE to convert a disk from the Master Boot Record (MBR) to the GUID Partition Table (GPT) partition style without modifying or deleting data on the disk.

First you need to move bootloader to drive with windows on it.
Currently bootloader is on 2TB disk (together with drive E: ).
Execute from elevated command prompt. Regular command prompt will give error on last step.
If you get any errors, then stop immediately and show screenshot with command output.

diskpart​

list disk​

select disk 2​

(select 1TB disk)​

list partition​

select partition 2​

(select 515MB recovery partition)​

delete partition override​

create partition primary size=500M​

format fs=ntfs quick​

active​

assign letter=H​

exit​

bcdboot C:\windows /s H:​

Last message should be "Boot files created successfully."

Next reboot and set 1TB drive as first in boot order.
Make sure, you can boot into windows after this.

Next proceed with drive conversion. Validate first and then convert.
Execute from elevated command prompt.

mbr2gpt /validate /disk:2 /allowFullOS​

mbr2gpt /convert /disk:2 /allowFullOS​

Reboot into BIOS.
Make sure UEFI boot is enabled.
Set first boot device to Windows Boot Manager.
Boot into windows.
