Why won't a PC boot after installing a new SSD? - Quora
Hi, I just bought a new 1 TB NVME SSD and installed it on my PC. I have my old 240 GB SATA SSD that I'm trying to start Windows from, but it just won't boot. I've tried to change the boot priority, and I've tried to boot directly from the SATA SSD, but my PC just won't boot. When I take the NVME SSD out and turn on my computer, it all works fine. Any help would be appreciated. - Reddit

Why PC Won't Boot After Installing M2 SSD

Why won't my computer boot after I install an M.2 hard drive? There are various reasons why this error can occur. The M.2 SSD may not be properly connected to the motherboard. The SSD may be faulty. The SSD may not be properly configured in the BIOS. See more details in the following content:

Ⓜ️M.2 SSD may not be properly connected to the motherboard. If it is not properly placed on the computer motherboard, it may not be recognized, and your computer may not boot properly from the M.2 SSD.

💡The M.2 SSD might not be properly configured in the BIOS. If the new SSD is your startup disk, but you have not set it as the startup disk in the BIOS, your computer will not be able to start Windows normally.

🔎The M.2 SSD may be damaged or malfunctioning. This error will also appear if the SSD is unhealthy or has other quality problems.

💻The PC's operating system or the motherboard may not be compatible with the new M.2 SSD. WIndows11 or WIndows 10 have specific installation requirements; when installing the system, ensure your SSD is compatible with the corresponding operating system.

How to Fix PC Won't Boot After Installing M2 SSD

M.2 SSD is an SSD with an M.2 interface. It targets high-performance storage in ultra-thin, power-constrained devices such as ultrabooks and tablets. Most of the time, it works fine, but many users have reported that their computers would not boot after a fresh installation of an M.2 SSD. Try the following solutions to fix it:

Fix 1. Check the Compatibility

You need to identify your computer motherboard model and specifications to verify compatibility. Find out the exact model number of your motherboard. This information is usually printed on the motherboard itself, or you can check the motherboard's manual, box, or manufacturer's website. Also, for M.2 SSDs, check that your motherboard has an M.2 slot and supports the specific key type required for SSDs (e.g., M Key, B Key).

Fix 2. Reinstall M.2 SSD

After installing the M.2 SSD, the computer cannot start normally; it may be that you have not installed the SSD hard disk correctly. You need to turn off the computer power, unplug the power cord, and then open the computer case (or open the back cover of the laptop). Remove the M.2 SSD and reinsert it securely into the M.2 slot. Make sure you align and secure the M.2 SSD correctly.
