    Windows won't start because a HDD is missing in BIOS. Correct?


    Facing problems: Windows won't start as some SATA-HDD is missing in BIOS. Most probably a HDD failure.
    It is not the startup disk though. Nonetheless Windows (10) won't start.
    I guess there is no alternative but to 'disable' the port in BIOS then.
    Hence no way to check whether I could still bring to live that disk...?

    I suggest you remove that disk from the computer and then check that the computer & Windows start correctly.
    Then, when the computer is up & running, you can connect the disk in, say, a USB enclosure to see what can be done with it.


    Best of luck,

    You can HotPlug SATA drives so disconnect the suspect drive and attempt a boot, then if you're happy the system is stable you can plug the suspect drive back in and test further.

    It's possible the boot files are on the wrong drive that's why it's not booting

    Sorry for the delay, thanks for the replies.
    Yes as per try3's suggestion I 'disabled' the drive in BIOS. Windows then booted (though it took a little while longer).
    Thanks try3!
    see screenshot below.

    In this scenario, if a drive doesn't work anymore, well, I guess it is just dead in 99% of the cases.


    I do not see any 'fallback' so as to be able to run whatever tools (e.g. from bootable USB) to see whether it can be brought back to life.
    I am not an expert, maybe MBR is missing or so?
    (until now I have no idea what I have stored on that drive...)


    In this respect, following may be off-topic, over the last few days I encountered something strange (related to above issue?)
    Whilst typing text, suddenly what I was typing didn't come through. Like, if I would type the word 'through', I had typed it all, but only the 't' showed up. I could wait, nothing happens, I could type the other characters, nothing happened, then maybe after 15-20 seconds I could continue. The taskmanager did not show anything special, consuming CPU or Memory and I have not installed something new. This was happening a number of times over the day and I still haven't figured out what it could have been.
    Defender scanning: nothing.

    Also a possible reason. Boot files are on the failed drive so it won't boot.
    A failing drive can prevent to boot from a healthy drive.
    First thing to try is to detach (SATA or power cable) the suspected drive (or disable the SATA port).

    We both posted at same time.
    As it booted without SATA_4 the drive is the problem.
    Set SATA_ 4a as enabled, set as Hot swap/plug and disconnect the SATA port cable.
    Boot and then attach the SATA cable.

    Hmm... I am not sure I understand (sorry)
    Windows is installed on an SSD (P1 in above screenshot) and everything is running fine, except then the drive from P4 is missing.
    Not sure what you mean with SATA_4a to enabled. Note, it was enabled, but then Windows did not boot. So I disabled it (screenshot bottom left)

    I got the Asus logo but that was it. The HDD led was on all the time, 10 minutes, 20 minutes. So, assume Windows could not 'handle' this 'faulty' drive.
