Ok, let me know if the BIOS update resolves the issue.
By the way, your system is booting from the C drive instead of the EFI partition. I think we can fix that after addressing the setup issue.

Hello, I've recently tried updating to windows 11 using 'Windows11InstallationAssistant.exe' but once my pc was restarted at the 30min mark and booted back up, I was still running windows 10 and all it added was a SYSTEM (E:) drive that I can't access. Did I do something wrong or what happened? I did run the windows pc health check tool to check if my pc can run windows 11 and was confirmed I could.

The setup encountered the error code 0xC1900101 - 0x20017. This error can be resolved by applying the latest BIOS update and installing the latest chipset drivers.
Your current BIOS version:
BIOS name : P1.00
BIOS version : P1.00
BIOS release date : 20190726000000.000000+000
Please visit the ASRock website and update the BIOS for your motherboard, which is B365M IB-R, according to the log.
