"I have 1TB storage on an HDD and I have a 240GB storage on an SSD. After I woke up this morning to hop on my PC. I realized I was booting from my HDD. Thinking I knew how to solve the issue, I opened my BIOS settings and went to boot order. My primary boot was my HDD so I tried to change it to my SSD. My SSD wasn't detected in my drives so I was confused. Why can't the BIOS detect my SSD? How to make it be detected again?"

One user had asked this question in an IT forum, wondering why the BIOS won't detect his SSD. In this article, we will focus on this issue to help any other users who encounter the same issue.

Why Can't the BIOS Detect My SSD?

First, we need to figure out the reasons why you can't see the SSD in BIOS. Actually, many factors would lead to such a problem. Below are the most common ones:

  • Hardware Faulty. A corrupted SSD port or SATA cable would also be the reason why you can't see the SSD in BIOS.
  • Outdated Motherboard. If your computer's motherboard is too old, it is possible that the motherboard or the onboard storage controllers were failing, and causing the BIOS to fail to detect your SSD.
  • The Default Boot Disk is HDD. If you had that HDD attached to the system when you installed Windows on the SSD, the EFI and boot partitions that existed previously on the HDD would trick the installer into believing that it does not need to create a new EFI and boot partition.
  • Corrupted SSD. Another common reason for BIOS won't detect SSD is that your SSD is corrupted.

Solution 1. Troubleshoot Hardware Faulty

If you can't make sure whether the SSD port or the SATA cable is working properly, follow the below guide to have a check.

1. Unplug your SSD, switch to another SSD port and see if it can be detected by BIOS.

2. Unplug the SSD, but keep the SATA cable connected. Then connect an HDD with the same SATA cable to your computer. Power back on and see if the system will boot into Windows. If it will, then you can make sure the SATA cable is well-functioned. You can try other methods to solve the problem.

Solution 2. Change the SSD Settings in BIOS

This method work for the wrong SATA controller mode. If the SATA controller mode is not set correctly and that's why your SSD is not recognized by BIOS. Change the SATA controller settings in BIOS would solve the problem. Here we take Lenovo laptops as an example.

Step 1. Restart your computer, and press the F2 key after the first screen.

Step 2. Press the Enter key to enter Config.

Step 3. Select Serial ATA and press Enter.

Step 4. In the SATA Controller Mode Option, choose the IDE Compatibility Mode.

Step 5. Save your changes and restart your computer to enter BIOS.

Solution 3. Disable HDD

This method only works for the condition that you have two hard disks, and have installed Windows on both of the two disks, but booted with the HDD before.
