The message “No signed device drivers were found” during Windows 10 setup usually means Windows Setup cannot see a required storage/USB controller driver on the PC, or the installation media/USB itself has an issue.
Try these steps in order:
- Recreate the Windows 10 installation USB
- On a working PC, download and recreate the Windows 10 installation media using the official Media Creation Tool.
- Use a different USB stick if possible.
- Plug this USB into a USB 2.0 port (if available) on the laptop and boot from it again.
- Move the USB to a different port during setup
- When the error appears, remove the USB installer, wait a few seconds, then plug it into a different USB port and click Back, then Next again.
- This can help if the original port needs a driver that is not included.
- Check for missing storage (disk) drivers
- If Windows Setup cannot see the 500 GB drive properly, the laptop might need a storage/RAID driver.
- On another PC, download the storage/SATA/RAID driver for that laptop from the laptop manufacturer’s support site and extract it to a separate USB drive.
- Start Windows Setup again. When the “No signed device drivers were found” message appears, choose the option to load a driver and point it to the second USB drive.
- If the correct driver is present, the disk should then appear and setup can continue.
- Add drivers using pnputil (advanced)
- If setup is running but cannot see the disk or controller, drivers can be injected from a USB:
- On another PC, download and unzip the needed drivers so that the
.inffiles are in the root of a USB drive (not inside subfolders). - On the laptop, boot to Windows Setup until the first screen appears.
- Press
Shift + F10to open Command Prompt. - Run
diskpart, thenlist volumeto find the USB drive letter. - Close DiskPart, then run:
pnputil /add-driver <USBDriveLetter>:\*.inf - Optionally run
pnputil /scan-devices. - Close Command Prompt and continue setup; the disk should now be visible if the correct driver was added.
- On another PC, download and unzip the needed drivers so that the
- If setup is running but cannot see the disk or controller, drivers can be injected from a USB:
- Verify the disk is detected by BIOS/UEFI
- Enter the laptop’s BIOS/UEFI setup and confirm the 500 GB drive is listed.
- If it is not listed there, the issue is hardware (cable/connector/drive) rather than drivers.
If, after these steps, the error persists and the 120 GB drive still works fine, the 500 GB drive or its connection may be faulty and should be checked or replaced.
