Dear Jacob_385!
Welcome to the Microsoft Community!
Don't worry. I will work with you to resolve the issue.
Based on the information you provided, I understand that your Windows 11 cannot properly recognize the SSD you installed, but you can normally recognize your new SATA interface SSD in the BIOS. This may be related to your BIOS settings being configured incorrectly. Sometimes, your BIOS settings may be set to the old IDE compatibility mode. This may cause the new SSD not to show up in the disk management of Windows 11. The solution here is to change the SATA mode to AHCI.
The steps listed here may be different on your computer, but they can give you a relatively general understanding of the process. Check the support or FAQ section on the manufacturer's website to find the exact steps.
1. Turn off your computer and then turn it back on. When the display lights up, press the Del, F2, or F12 key or the relevant key of the system manufacturer to enter the BIOS setup.
2. Find and click Storage, and then select the Storage Options entry.
3. Now, set SATA emulation to AHCI mode and save the changes.
4. Once completed, boot Windows 11 and the SSD should now be recognized. If it is still not listed, proceed to the following method.

If you are going to modify BIOS Settings, please back up all your personal files first to ensure you do not lose data.
Update SSD Drivers
1. Open the Search menu in the taskbar search box, enter Device Manager in the top text field, and click the relevant search result.
2. Double-click the Disk drives entry to expand and view the problematic SSD
3. Right-click the unrecognized SSD and select Update Driver from the context menu.
4. Next, select Search automatically for drivers from the two options in the Update Drivers window.
5. Your computer will now scan the best driver available on your system and install it to the SSD.
We have also shared some strange solutions for new SSDs that cannot be recognized by Windows normally. You can refer to whether they are applicable to your current situation:

The above are my preliminary judgment of possible factors and solutions. If you still don’t work after trying the above solutions, we may need to communicate further, because online communication may not be able to diagnose the specific cause for you immediately, and the specific situation may even be related to the specific settings of your motherboard.
Thank you for your patience and support!
