Please make sure you have installed the operating system in RAID and not in AHCI.
You will need to access the BIOS and set the SATA mode to RAID in order to create a RAID or to accelerate your system with the SSD.
Please provide me with the Intel® RST System Reports; you can follow the steps to get the report here:
Although I had originally installed the new OS in AHCI, I followed instructions to uninstall the RST drivers, restart the PC into Safe Boot and switch the BIOS to RAID. This allowed me then to reboot Windows normally without an error and now my BIOS does show the SATA mode as RAID. The latest version of RST was then reinstalled.
I have attached the RST System Report, thanks.

This is a special situation. The configuration that OEMs or computer manufactures include in their systems runs just fine when using the original Operating System image but when this image is removed or change, the configurations will go away.
My best recommendation is to take to factory settings the computer since you have a Dell system but you can try the following:
- Change the chipset mode to RAID before installing the operating system.
- It is recommendable not to have partitions on the SSD nor Format.
