> We can't debug or support a boot entry that we can't examine. I can understand that. I do hope that this "Linpus Lite" is a corner case. Otherwise, if this kind of USB boot systems will get common in UEFI mode, Ubuntu will have severe problems.
> When you say AHCI, do you mean UEFI? AHCI has no relevance to USB boot. I mean AHCI and I know that it should have no relevance to USB boot. I mentioned it because it was the only thing in the UEFI/BIOS system, that was modified by a user (before this debugging started). -o- I have spent hours to search for and test various options in the UEFI/BIOS menu system, but no, I find no way to directly select the USB drive for booting under UEFI after firmware upgrade, instead of using the 'Linpus Lite' boot option. Personally, I don't mind using BIOS mode alias CSM alias legacy mode. And during 5 years, I can install Ubuntu 20.04.1 LTS via this 'Linpus Lite' boot option and get a system with security updates and that way dual boot with the original Windows 10 system in UEFI mode. So I won't push this issue further.
