I'll try to make long story short, but I'm probably going to fail.
I am trying to UPGRADE from my current Windows 10 Home (22H2) to Windows 11. I think this particular drive started out as Windows 8.1 with a computer I bought back in 2014?
PC Health check says all good. Every method I've tried:
- Windows Update though Settings > Update & Security
- Update Assistant download from Microsoft
- ISO media download from Microsoft
They all go to 87%, and it fails.
I have a AsusTek PRIME B450M-A II mobo. BIOS Version/Date 3810, 11/21/2022
Things I've done to get it ready:
- Converted boot drive from MBR to GPT
- Fast boot disabled in BIOS
- All boot devices = UEFI only (no legacy)
- CSM disabled (REBAR=ON)
Doing all those things and rebooting get me into my current Windows 10 just fine, and everything is working.
The only issue is Secure boot state is still OFF.

Up to this point we're good, but I don't want to try to install Windows 11 again until I get this to ON.
So when I go into the BIOS, and change BOOT > OS Type from OtherOS to Windows UEFI mode... save config and restart, the following maladies pop up.

- Network adapter/ethernet shows as down. All attempts to troubleshoot it via troubleshooter fail. Disabling/reenabling fails. Updating driver to latest driver does nothing. Internet is dead. See image below.
- Comodo Firewall says it's not functioning properly, because of above network adapter issue.
- NORDVPN TAP-NordVPN Windows adapter V9 shows with yellow triangle in Device Manager. Also related to above.
- UPS powerpanel Personal Service is not running, not communicating with the UPS. UPS connected to computer via USB cable for power monitoring.
UPS won't talk to me
There might be a host of other issues, but I'm not going to dive deeper, there's enough here to see it ain't working. These are the errors I'm getting when I run the diagnostic on the Troubleshooter.
Windows couldn't automatically bind the IP protocol stack to the network adapter.

Additionally, when I run the troubleshooter, it finds a mystery adapter that I can't spot anywhere.. calls it Eth2, but the only one I see in Network manager is Eth3 which isn't working.
eth2, who r u?
I've tried every type of Google search to figure out what I'm missing and I'm stumped beyond all reason. So I go back into BIOS and change Windows UEFI mode > OtherOS > Restart... and will you look at that:
Boot state is now off
Powerpanel online, Internet restored
So my questions now are either:
- Do I need SecureBoot state ON in order to try upgrading Windows 10 to 11?
- If yes, then what must I do to fix all these broken components within Windows when the mode is on? I saw something in the BIOS about key management.. but I sure as hell don't want to touch that right now. Currently there are many keys set under PK/KEK/DB/and DBK.
Thanks in advance to anyone who wants to touch this turd of an Install. I'll be grateful if it ends up being installable at this point without SecureBoot, but all advice appreciated before I burn another cycle off my SSD for an upgrade attempt.
