Tried again after having had to stop manually the PC.
Seemed to install the requested .inf file, but upon restart the situation remains the same, with the AHCI device working and no sign of the IDE device in device manager.
Mast have done something wrong.

@Tranfa:
Did you switch the SATA mode of the SATA Controller to "IDE" before you finally rebooted?
If yes, are you sure, that you did it with the correct SATA Controller (Intel or ASMedia), where your system drive is connected?

My current System:
MB: ASRock X570 Pro4, CPU: AMD Ryzen 5 3600, System Drive: 500 GB Samsung 980 Pro, Graphics: Sapphire Radeon RX570, OS: Win10 x64 Pro

Yes to both, unfortunately...
I think the �driver update� didn�t go through, for some reason.

Zitat von Tranfa im Beitrag #21
I think the �driver update� didn�t go through, for some reason.

Yes, the switch from AHCI to IDE (or vice versa) from within a running OS is risky, because the Windows Hardware Detection doesn't like to install a mass storage driver, which doesn't match the HardwareIDs of the SATA Controller, where the system drive is connected (the DeviceIDs of the SATA Controller depends on the SATA mode and are different in IDE, AHCI and RAID mode).
That is why I always recommend to do a fresh OS installation, when the user wants to switch the SATA mode.

Another question: Are you sure, that you saved the changed SATA mode setting, before you have quit the BIOS?

Yes I did. I�ll try to solve with a sort of equivalent of a fresh install: a restore of the whole disk backup. Thanks a lot for your help and knowledge sharing, Fernando.

The restore worked fine, I can boot from all partitions now. And unsurprisingly, in win10 I find the IDE device you mentioned... :)
