Many people look to upgrade their Windows 10 PC to Windows 11, but encounter an issue where the Windows 11 installer does not detect or see their SSD drive during installation. This prevents the user from being able to install Windows 11 and leaves them stuck on Windows 10.
This can occur with both SATA and NVMe SSDs and is usually caused by configuration or hardware issues rather than a problem with the drive itself. Some common reasons the Windows 11 installer may not see the SSD include loose connections, needing a driver update, or incorrect SATA settings in the BIOS. With some troubleshooting steps, the SSD can usually be detected and Windows 11 installation completed successfully.
This article provides an overview of why the Windows 11 installer may not detect an SSD and the various solutions to fix the problem. Following the troubleshooting steps provided can help users properly install Windows 11 on their SSD.
System Requirements
To install Windows 11, a computer must meet specific minimum system requirements. Microsoft designed Windows 11 to only work on newer PCs with modern hardware in order to take full advantage of the operating system’s features and security enhancements. The key system requirements include:
UEFI and Secure Boot – The PC must have a Unified Extensible Firmware Interface (UEFI) instead of the older Basic Input/Output System (BIOS) firmware. Secure Boot must be enabled in UEFI. These ensure firmware-level security protections.
TPM 2.0 – A Trusted Platform Module (TPM) version 2.0 chip is required. The TPM 2.0 is a crypto-processor that enhances system security.
CPU – The processor must be 1 GHz or faster with at least 2 cores and support 64-bit architecture. Specific Intel, AMD, and Qualcomm processors are listed as compatible.
RAM – At least 4GB of RAM is required to run Windows 11.
Storage – The PC needs 64GB of storage space or larger available.
Graphics card – A DirectX 12 compatible graphics card with Windows Display Driver Model (WDDM) 2.0 drivers is required.
Screen – Windows 11 requires a minimum display size of 9 inches diagonally with 720p resolution.
Internet connectivity – Windows 11 Home edition requires internet connectivity and a Microsoft account to complete device setup.
These system requirements ensure Windows 11 provides improved security defenses, better performance, and the latest tech experiences compared to previous Windows versions. Meeting the minimum hardware specifications is necessary for the operating system to function reliably.
UEFI and Secure Boot Requirements
Windows 11 requires Unified Extensible Firmware Interface (UEFI) and Secure Boot to be enabled in the BIOS settings. UEFI is a modern firmware standard that replaced the legacy BIOS firmware. Secure Boot helps protect the boot process by verifying the integrity of the OS bootloader and kernel through digital signatures.
To install Windows 11, you need to have a 64-bit CPU that supports UEFI, Secure Boot capable firmware, TPM 2.0, and a compatible graphics card. With UEFI and Secure Boot enabled, the firmware will check the signature of the OS bootloader files before loading Windows. This prevents malicious software from modifying the boot process.[1]
If you are upgrading from Windows 10, you may need to switch from legacy BIOS to UEFI firmware and enable Secure Boot in the BIOS settings. Consult your motherboard manual on how to do this. Some older systems may not support UEFI and Secure Boot.
TPM Requirement
One of the key requirements for Windows 11 is a TPM (Trusted Platform Module), which is a chip that provides hardware-based security features. TPM 2.0 or later is required to install and run Windows 11.
TPM provides encryption for securing sensitive data as well as platform integrity validation for malware protection TPM recommendations – Windows Security. Specifically, Windows 11 leverages TPM for features like Secure Boot, Windows Hello, and BitLocker. TPM 2.0 supports more advanced cryptographic algorithms compared to TPM 1.2, which is why Microsoft made it a requirement.
The vast majority of modern machines produced in the last several years have TPM 2.0. To check if your machine has a compatible TPM version, you can use the Windows PC Health Check app or check in the BIOS. If your PC does not meet the TPM 2.0 requirement, there are a couple options:
- Enable TPM in the BIOS if available but disabled. Many machines have TPM capability that needs to be switched on.
- For older systems without TPM 2.0, you can purchase and install a TPM module, either pluggable or soldered onto the motherboard. However, this will only work if the hardware and BIOS support TPM.
With the right compatible hardware, TPM should not be a barrier to installing Windows 11. Activating TPM capabilities already present or adding a supported module enables meeting this key security requirement.
Hard Drive Compatibility
Windows 11 requires your hard drive use a GPT partition style rather than MBR. Most hard drives manufactured in the last 10 years use GPT, including both HDDs and SSDs.
Seagate external hard drives like the Backup Plus, Ultra Touch, One Touch, and Fast SSD families are compatible with Windows 11 according to Seagate’s support article (https://www.seagate.com/support/kb/will-my-seagate-drive-work-with-windows-11/). Any newer external drive from a major brand should work. Older MBR formatted drives may need to be reformatted to GPT to be detected during Windows 11 installation.
If your SSD or HDD is recognized properly in the BIOS but the Windows 11 installer is not seeing it, the drive itself is likely compatible. The issues may be related to connections, drivers, or BIOS settings instead.
SSD Not Detected
There are a few common reasons why an SSD may not be detected during Windows 11 installation:
A loose connection is one of the most likely culprits. The SATA cable connecting the SSD to the motherboard may have come loose or become disconnected, either from cable issues or moving the computer [1]. Reseating the connections at both ends can often resolve this.
Outdated or missing drivers can also prevent Windows 11 from recognizing the SSD. Windows may lack the proper drivers to communicate with newer SSD models. Downloading the latest SSD drivers from the manufacturer and integrating them into the Windows 11 installer may be required [2].
Incompatible SATA settings in the BIOS can cause detection issues too. The BIOS may be configured for IDE or RAID instead of AHCI mode, which is required for SSDs. Entering the BIOS and switching the SATA settings to AHCI can resolve this [3].
Damaged SSDs or other hardware issues like a failed SATA controller could also prevent detection. But connection and configuration problems are much more likely causes with otherwise healthy drives and systems.
Checking Connections
One of the most common reasons an SSD may not be detected in Windows is because it has become physically disconnected. Before troubleshooting software issues, it’s important to verify all the physical connections to ensure the SSD is properly connected.
First, make sure both ends of the SATA data cable are securely plugged into the SSD and motherboard SATA ports. The cable should be fully inserted straight into the port without bending or crimping. Wiggling the cable may produce a better connection or reveal a loose port.
If using an M.2 SSD, inspect the slot to ensure the drive is fully seated and screwed into place per your motherboard manual instructions. With M.2 drives, even slightly loose screws can cause connection issues.
Additionally, check that the SSD is receiving consistent power by ensuring the power cable from the PSU is firmly plugged into the SSD. If using SATA, verify the drive spins up when powered on. For M.2 SSDs, check for an illuminated LED activity light if available.
Finally, try connecting the SSD to another SATA port and using a different SATA cable if available. This helps rule out any issues with the specific port or cable used.
Thoroughly checking all physical connections is crucial before assuming the issue lies with drivers or SATA configurations in software. Proper SSD connections are required for detection and stable performance.

Updating Drivers
One potential reason Windows 11 installation may not detect a new SSD is outdated drivers. Both the disk controller driver and SSD firmware should be fully updated before attempting to install Windows 11.
To update the disk controller driver, visit the manufacturer’s website and download the latest version. Install this driver before proceeding with the OS installation. For NVMe drives, you can also use the Storage Firmware Update tool in Windows to update the firmware.
The SSD firmware itself also needs to be up-to-date. Most SSD manufacturers provide firmware update tools to flash the drive with the latest firmware. Consult your SSD manufacturer’s website and follow their instructions to update the firmware. This ensures full compatibility with Windows 11.
With optimized drivers and updated firmware, the Windows 11 installer should now be able to successfully detect the new SSD.
Changing SATA Settings
One potential reason why Windows 11 is not detecting a new SSD is if the SATA settings in the BIOS are configured for RAID instead of AHCI. Many newer motherboards support both RAID and AHCI SATA modes. However, switching between these modes requires reconfiguring Windows.
If the BIOS is set to RAID mode when installing Windows, changing to AHCI later can prevent Windows from booting properly. This is because the Windows boot configuration expects RAID drivers to be loaded during startup. With AHCI mode enabled instead, the system will fail to load Windows correctly.
To change from RAID to AHCI without reinstalling Windows, you will need to make the switch before booting into Windows again [1]:
- In the BIOS, change the SATA operation mode from RAID to AHCI.
- Save changes and exit the BIOS.
- Windows will automatically boot into Safe Mode.
- Open an elevated command prompt and run:
bcdedit /set {current} safeboot minimal - Reboot the computer normally and AHCI mode will be enabled.
This process inserts a safeboot flag that prompts Windows to load minimal drivers, avoiding the RAID driver dependency issue. After booting successfully with AHCI, you can remove the safeboot flag by running: bcdedit /deletevalue {current} safeboot
With AHCI mode enabled in the BIOS, Windows should now be able to detect and install drivers for a new SSD. If Windows still does not see the SSD, further troubleshooting may be needed.
Conclusion
If you are trying to install Windows 11 but the installer is not detecting your new SSD, there are a few things to check. First, make sure your SSD meets the system requirements and is connected properly. Check that the SATA controller and SSD firmware drivers are fully up to date. You may need to change the SATA settings in your BIOS from AHCI to IDE or RAID.
As a final step, you can try disconnecting all other drives except the target SSD during Windows 11 installation to force the installer to see the drive. With some troubleshooting and correctly configured hardware, you should be able to get Windows 11 running on that new SSD.
