Did you do a clean reinstall of Win 10 on the boot drive (the SSD?) ? Just breaking the RAID probably won't work...

@Shawn1028 

You need to create OS recovery media and install OS on the SSD.

Welcome to the Dell Community @Shawn1028 

Use the Dell OS Recovery Tool to create a USB recovery drive that you can use to reinstall the version of Windows or Linux that came with your PC:

For a clean Windows 10 install:

You can make a W10 USB flash drive installer with the Microsoft Media Creation Tool, using a 16GB flash drive using another Windows PC, if your PC is not working.

If you are asked to enter a product key during the installation process, select the 'I don't have a product key' option, and W10 will install and automatically activate once you are connected to the internet.

Here are the steps to create the W10 USB flash drive installer...

Select Download tool now, and select Run. If you agree to the license terms, select Accept.

On the What do you want to do? page, select Create installation media for another PC, and then select Next.

Select the language, edition, and architecture (64-bit or 32-bit) for Windows 10.

Select which media you want to use:

USB flash drive.

Plug in a blank USB flash drive with at least 16GB of space. Any content on the flash drive will be deleted.

After W10 installs, you can install the drivers and available software from your notebook's support page.
