Damaged Windows 10 by changing Storage Spaces Controller

[robvazdom]

Hi, so I think I've royally screwed up.

While trying to install Ubuntu to my SSD drive I ran into a guide that recommended the following instructions:

1. Boot to Windows with your current SATA controller configuration
2. Open Device Manager
3. Expand Storage Controllers and identify the Intel SATA RAID Controller
4. View properties of the identified controller
5. On the Driver tab, click the Update driver… button
6. Browse my computer…, Let me pick… Uncheck Show compatible hardware
7. Select Microsoft as manufacturer
8. Select Microsoft Storage Spaces Controller as model3
9. Accept that Windows cannot confirm that this driver is compatible
10. Save changes, reboot to BIOS and change RAID SATA Controller to AHCI
    
    My HP Envy is already AHCI. I was unable to perform this last step and now my Windows 10 OS is completely unusable. This is a brand new computer so I don't have any backups to restore to, and none of the repair tools are working so far. Tried with HP recovery tools but they appear grayed out. None of the normal recovery tools works for me at all. Is there any way of repairing my OS? Thanks in advance!

So basically, you tried to force a change of your controller from RAID to AHCI?  And you are surprised that trashed your PC?

What MIGHT work is pressing the Esc key repeatedly and when the text menu comes us, select the option to go into Settings.  If this works, this will get you into the UEFI/BIOS settings -- and once in there, you might be able to find an option to reset the storage back to RAID (if that is what it was, originally).

Otherwise, you could also (while at the text menu) choose the Recovery option and see if you can then reset your PC back its factory settings. If that works, that will erase everything on your drive, reinstalling the setup from scratch.
