Installed a fresh SSD, configured a new operating system, and removed the old OS files. Everything operated smoothly for three days, but today, the PC unexpectedly refuses to start. What’s the cause?

Troubleshooting a Sudden Boot Failure with a New SSD: My Experience

Recently, I upgraded my system by installing a new SSD and setting up a fresh operating system. Initially, everything functioned perfectly for three days. However, without any warning, my PC failed to boot, displaying the error message: “Required device not found.”

After this incident, I found myself unable to access recovery mode or to make any progress in booting up the system. I booted from a recovery media and attempted to investigate the issue using the Command Prompt and Diskpart. Strangely, while the SSD appeared to be online, the partitions themselves were offline. This was puzzling.

Given the urgency of the situation and the limited amount of data on the drive, I chose to take the drastic step of cleaning the SSD. I reformatted it to the GPT structure and reinstalled Windows from scratch.

System Details:

• Device: Dell G3 3579
• SSD: WD NVMe M.2 SSD

Seeking Answers

I’m very much interested in understanding the causes behind this unexpected boot failure. What could have triggered this series of events? Why were the partitions offline even though Diskpart recognized the disk as online? Any insights into this situation would be greatly appreciated, as I want to prevent a recurrence in the future. Thank you!

Update:

Upon further examination, it seems that the current consensus is that the SSD might have become disconnected for some reason, leading to the partitions being dismounted and rendered offline. I plan to keep this post updated with any additional findings or developments regarding the issue. Stay tuned for more information!
