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.
