Troubleshooting Boot Issues: SSD Recognized but Not Booting

If you’ve recently upgraded your system or transferred an SSD from another computer, you may encounter a frustrating issue: your SSD is detected in the BIOS, yet your system fails to boot from it. I’ve faced this situation with my own hardware setup, and I want to share my experience and insights to help others who might be in a similar predicament.

The Setup

In my case, I was using a Crucial MX500 1TB SSD that I had originally installed with Windows on a different machine. My goal was to conduct a fresh installation of Windows on this drive. However, despite my previous experience with similar setups, I was met with an unexpected hurdle—my motherboard, an Asus TUF X570 Plus with BIOS version 1405, recognized the SSD as a storage device but would not allow me to boot from it.

Understanding the Problem

When an SSD is recognized in the BIOS but you are unable to boot from it, there could be several underlying causes:

  1. Boot Order Configuration: One common issue might be the order of boot devices. It’s crucial to ensure that your motherboard is set to prioritize the SSD as the first boot option in the BIOS settings.

  2. Legacy vs. UEFI Mode: Depending on how Windows was originally installed on your SSD, the system might be trying to boot in the wrong mode. If Windows was installed in UEFI mode and your BIOS is set to Legacy mode (or vice versa), it could lead to boot failures.

  3. Corrupted Installation: If you transferred the SSD from another rig, there’s a chance the Windows installation is not compatible with your current hardware, especially if major changes have been made.

  4. Connection Issues: Although this is less common, ensure that the SSD is properly connected to the motherboard and that the SATA cable is functional.

Troubleshooting Steps

Here are a few steps to help you diagnose and potentially resolve the issue:

  • Check the Boot Priority: Enter your BIOS settings and confirm that the SSD is set as the primary boot device.

  • Review Boot Mode Settings: Check whether your BIOS is configured for UEFI or Legacy mode, and adjust accordingly to match how Windows was installed on the SSD.

  • Consider a Fresh Install: If all else fails, it might be worthwhile to proceed with a fresh installation of Windows on the SSD. Ensure that you

  1. Thank you for sharing your detailed experience. When encountering a scenario where the SSD is recognized in BIOS but the system won’t boot from it, here are some additional troubleshooting tips that might help:

    • Verify Boot Mode Compatibility: Ensure that your BIOS is configured consistently with how Windows was installed—either UEFI or Legacy. Mismatched modes can prevent booting. You can usually find this setting under BIOS > Boot > Boot Mode or CSM settings.
    • Rebuild the Boot Configuration Data (BCD): If the Windows installation on the SSD is corrupted or misconfigured, repairing the BCD might resolve boot issues. You can do this using a Windows installation media:
      1. Boot from the Windows recovery media.
      2. Navigate to ‘Repair your computer’ > ‘Troubleshoot’ > ‘Advanced options’ > ‘Command Prompt’.
      3. Run the following commands: 
        bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd
      4. Reboot and see if the system can now boot from the SSD.
    • Check Secure Boot Settings: Sometimes, Secure Boot can interfere with booting from a drive with an OS installed in UEFI mode. Try disabling Secure Boot in your BIOS to test if that
