What to Do If Your Laptop or PC Doesn’t Detect Drives During Windows Installation

Encountering an issue where your laptop or PC doesn’t recognize drives during a Windows installation is a common problem. This can happen for several reasons, including incompatible drivers, incorrect BIOS settings, or faulty hard drives. Here’s a step-by-step guide to help you resolve this issue.

Check Your BIOS Settings

Start by entering the BIOS. To access it, restart your device and press the appropriate key (typically F2, F12, DEL, or ESC, depending on your laptop model or motherboard). In BIOS, ensure that your disk is set as the Primary Boot Device and that the SATA or AHCI mode is selected instead of IDE.

Update the SATA Controller Drivers

If the BIOS is set up correctly but Windows still doesn’t detect the drive, the issue could be due to missing drivers. Some newer laptops and desktops require specific SATA controller drivers, which you can download separately and add during the Windows installation using a USB drive. Download the drivers from your device manufacturer’s website, save them on a flash drive, and connect it during the Windows installation, selecting the “Load Driver” option.

Check the Drive Connection

Sometimes, the issue is with a loose or improperly connected drive. This is more common with desktop PCs, where cables may loosen or corrode. Open your computer case and make sure the SATA cable and power cable for the hard drive are firmly connected. If it's a laptop, and if possible, try temporarily disconnecting and reconnecting the drive.

Use Disk Diagnostic Tools

If the drive still isn’t detected, it might be damaged. Use diagnostic utilities like Hiren's Boot CD or similar programs to check the drive’s health. If the tool cannot detect the drive or reports errors, the drive may need to be replaced.

Repartition and Format the Drive

In some cases, the drive might lack a valid partition. Connect the drive to another computer and use Windows Disk Management to format it. Create a new partition, ensure it’s visible and recognized by the system, and then try the Windows installation again.
