Cannot change Boot Order

[Bowline5]

Every few weeks I come back to this problem, I cannot get my computer to boot from a disc or USB drive, it always defaults back to the hard drive OS. The BIOS version is F.28 from AMI, I can change the boot order in UEFI and Legacy sequences but the hard drive OS option in both lists is marked by a black arrow, presumably indicating a default setting. If I were a cynic I would say that this was written in specifically to prevent me from bypassing Windows 10 so that I can control what my computer does and when rather than be dictated to by the Microsoft gnomes. Am I stuck with it or is there a way round these default settings? I know that there is an option to select to boot from USB contained within Windows 10, but that is only one of the many built in programs and utilities that deliver only error messages stating that they have failed to start.

@Bowline5 Welcome to HP Community! Did you try turning off the legacy support/secure boot? If not, please check this link: click here

That said, HP has locked a few settings on your computer which are being managed by the system configuration as the device is configured to its optimal performance.

If you've already attempted to update the BIOS and yet the issue persists, there's no way of resetting or changing these locked settings via HP articles or assistance,

You could unlock and make changes at your own discretion using 3rd party tools, however, HP doesn't recommend the same nor has information about the tools used.

I hope you understand.

I hope that answers your query,
