I’ve been recommended to do a fully CMOS reset by pulling out battery but don’t really have time. It disappeared after a BIOS update :)

Did you load the default BIOS settings after that? If not, that might be easier than removing the battery.

And if you did, the default settings could have enabled the CSM, or changed other settings like fast boot that might make the drive not show up.

Have you checked your BIOS if CSM is enabled (gets disabled when enabling secure boot iirc)? If your Linux drive has an old partitioning scheme it needs that to show up during boot I think.

Yeah, all this automation with robots and AIs could (and should) be good for all people. All it takes is distributing the value of that automated labor to all of them and not enrich a few selfish fucks. Of course none of them realize (or say aloud) that for that to happen, all the money their companies gain needs to be taken from them again (or they need to give it voluntarily).
