I had seen basically the same answer on another site, but being an admitted command line dummy, I figured I'd try here. Is that syntax exactly how it should go? Nothing specific to my computer that would replace whats in brackets, parenthesis, etc?

This came from Dell with that RAID on setting, with only one SSD, why would it be set that way?

Thank you!

It is simpler for Dell to install the software image on a base of different models all using the same RAID driver than it is on a base of models with different makes and models of SSD.

While it IS possible to switch from RAID to AHCI, make absolutely sure you have a full system backup that's been verified before you try.  Things can and do go wrong.

Then see

https://superuser.com/questions/1280141/switch-raid-to-ahci-without-reinstalling-windows-10

This does not require using the command line at all.

Ok, right outta the gate, I get this:

C:\WINDOWS\system32>bcdedit /set {current} safeboot minimal (ALT: bcdedit /set safeboot minimal)
Invalid command line switch: /set
Run "bcdedit /?" for command line assistance.
The parameter is incorrect.

Would this be installing the right driver before changing from RAID to AHCI?

My current storage controller driver shows as Intel Chipset SATA/PCIe RST Premium controller.

What driver would I need?

Or, from reading other posts regarding RAID vs AHCI, it seems that I can make the change in the BIOS settings, boot in safe mode (hold shift key while booting, etc.) windows should load driver, then reboot normally?

I could always change BIOS settings back, right? Nothing in all this will render computer un-bootable, right?

What driver would that be?

The faster easier way of getting into safemode is via msconfig. As it's rebooting mash F2 to enter bios>system config>change the sata operation>apply/exit/reboot>go back into msconfig and uncheck safemode>reboot. Done. You have now changed from RAID to AHCI

A third option to reboot a Windows 10 system in safe mode without typing any CMD command is to go Start Menu > Settings > Recovery > Advanced start. On reboot you will be offered options to start in safe mode with or without network capabilities or even directly to a CMD console. Of course, you will have to change to SATA mode in BIOS/UEFI as mentioned above. The accurate sequence to reboot in safe mode this way might have beeen slightly different for versions of Windows 10 prior to 22H2 but as simple. This feature is also available in Windows 11 through a slightly different path from Start Menu.

@AdrianG001​ This only results in a screen which says my pin is unavailable, and I am stuck in a Boot loop. If I boot in with an installation thumb drive then I can use Repair My PC to get to bcdedit and get out of Safe Mode. As far as I can see the only way to install the correct driver is to set the BIOS to AHCI and reinstall Windows.

@addyman10​ That led me to the same Boot Loop problem as AdrianG001's method.
