Can't say anything about secure boot, but we have HP at work and the BIOS is the most brain damaged thing ever. Just the built-in update process... It doesn't always find the latest version, ie lags behind the website by weeks sometimes. Then when it checks for updates and finds there isn't a new version available, it offers you to downgrade to the previous version but apart from the text being a bit different, the blue button below still says "UPGRADE", so the first time I accidentally started a downgrade. So it started flashing the BIOS, then something like the nic firmware, then came to the Intel ME firmware and suddenly said "uh no, I cannot downgrade that" and just aborted the whole update process. No idea if it would've kept flashing other stuff after the ME, and evidently it didn't break anything, but holy crap that looks like a half-arsed feature.
