Troubleshooting an M.2 SSD Detected in BIOS but Not in Windows: A Professional Guide
Introduction
Solid-state drives (SSDs) have revolutionized data storage, offering faster speeds and enhanced reliability. However, encountering issues where the drive appears in BIOS but remains undiscoverable within Windows can be perplexing. This article explores common causes for this problem and provides structured troubleshooting steps, using a real-world scenario involving a Patriot Viper VP4300 1TB M.2 PCIe 4.0 SSD.
