<p>Some SATA/NVME devices have dual modes, settable in the BIOS.
They might, e.g., have a RAID mode etc. Some of those modes are
not supported by Linux. Resetting that in the BIOS should make at
least your bootable DoK see the disk again.</p>

<p>What I don't understand is why your Windows would stop booting.
At the very least, it should start the boot process and BSoD when
the disk drivers have changed for it.</p>
