T520 BIOS update and Windows 10 version 1607 failure

Hi -

I know the T520 is old, but mine is in excellent shape (new keyboard, new hard drive) and I want to keep it a little while longer. Windows 10 is trying to install version 1607, and it fails every time. Microsoft support says I need to deactive Secure Boot in the BIOS, but the T520 does not seem to have that option. My BIOS version is 8AET46WW (1.26) and I would like to know if it is possible to update this BIOS any more. I don't see any information or downloads anywhere that indicate that it is possible. None of the Lenovo tools seem to work, and the System Update tool only proposes to update my SD card reader driver!

Thanks a million for any advice you may have.

How are you updating from inside the OS or a CD? How does it fail? Do you get an error? Secure boot should be under the security tab in setup/bios.

That's quite an old version. To upgrade the BIOS I would recommend to use the ISO download and burn it to a CD. You can get the drivers from the Lenovo Support page.

Great, thank you for the advice. I can handle that technically. Do you think it could help my problem? Do you know if the "Secure Boot" option was introduced at all?

I'm not so sure, but the list of changes after v1.26 is quite long. Let us know if you still don't find the secure boot option.

 

Edit, I think you need to set the boot options like this:

And make sure the Boot priority is set to USB HDD on top!

The Windows Update is automatic, and has already tried to install itself several times. Each time I end up with a spinning circle/dark screen, and after a couple of those it restores the previous version. I'm relatively sure that it won't continue to restore correctly forever! I keep postponing the installation. But sometimes it does it if I reboot.
For Secure Boot, I will look in the BIOS again. I looked yesterday and did not see anything under security that had anything like "Secure Boot" in it. Perhaps that's something that was added later? I'll take another look this evening. I appreciate your taking the time to respond.
