Windows 10: Inaccessible boot device - reinstall storage controller

Hi,


I have a Dell Precision 3530 with a PCIe SSD. In a try to get Windows to see my newly installed secondary m.2 SATA SSD, I've set the "BIOS" (UEFI) from RAID mode to AHCI mode. The boot was unsuccessful, now I get BSOD with "Inaccessible boot device" even after reverting to RAID mode.


Prior to the AHCI reboot, I've also removed both* Intel Rapid Storage controller drivers so that the default Microsoft Storage Space controller be used in the AHCI mode.

* In the Storage controllers branch in Device Manager, I had four entries: An Intel RST, an Intel RST Premium, and two MS Storage Space controller instances. This is how I received the laptop from the reseller.


Right now Windows sees my system disk, partitions and files. I can use the recovery command line, or boot to a recovery safe mode (e.g., not my OS). No booting though. Automatic repair cannot fix the problem.


The system disk has GPT partitions. diskpart / list vol shows my partitions with no flags in the Info column, except for the ESP partition which is hidden.


Is there any way to reinstall/reset the missing/problematic storage controller drivers?

:)

I'm not sure if this is helpful, but maybe you can have a try. Windows operating system backups a working registry for recovery purpose. You can perform registry backup restoring to fix the inaccessible boot device error. The pre-condition is that you can access to the Advanced startup opotions of your PC. You'll need to use the command prompt.
Also, steps are a little bit complicated. However, if you follow the guide strictly, no mistake should be made. You can Google how to restore from Registry Backup, or refer to this article for help. Inaccessible Boot Device Lenovo.
