Windows 10: windows asking to reinstall after switching to ahci

I needed to dual boot my windows 11 with ubuntu on dell laptop. When i started installing ubuntu i needed to switch to ahci and i did it without the safeboot process and now my ubuntu installed succesfully. I can access all my windows data from ubuntu but when i try to boot windows its asking me to reinstall windows and even the factory image reset option doesnot work.Is there any way for me to get back to windows.

WIndows Reinstall Switch From RAID to AHCI

Hello all,

My laptop (specs listed in other under system specs) uses a Samsung PM830 SSD. Samsung Magician says it doesnt support this drive, even though the online documentation says it does. The only reason for this that Ive been able to find is because the laptop is set up to run drives in RAID or what Intel calls IRRT. I read somewhere that for Magician to see the drive, it has to be run as AHCI. So what Im looking to do is switch it over to AHCI from RAID. I know this will take a reinstall of Windows to do, but I dont want to do it from scratch. I have a backup of the OS drive made using AOMEI Backupper.

My question is, can I switch it over and restore the system using this backup, or will it force me to do a clean install?

 

WIndows Reinstall Switch From RAID to AHCI

Did you replace the standard AHCI controller with Intel's driver?

 

Switch from Raid On to AHCI (and vice versa) on reboot via script

Windows can be switch from Raid On to AHCI.
I bring below the procedure described in the article
How to switch SATA controller driver from RAID to AHCI on Windows 10 without a reinstall.
I suggest to take backups first, including an image backup of the Windows partition.

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…
   
7. Uncheck Show compatible hardware
   
8. Select Microsoft as manufacturer
   
9. Select Microsoft Storage Spaces Controller as model3
   
10. Accept that Windows cannot confirm that this driver is compatible
    
11. Save changes, reboot to BIOS and change RAID SATA Controller to AHCI
    
12. Save changes and reboot normally, hopefully to Windows
    

An alternative solution that involves using bcdedit can be found in
Switch Windows 10 from RAID/IDE to AHCI operation
(although I like it less when grub is involved).
