Why Linux Mint OS is not recognizing internal M.2 SSD

 Q:Why Linux Mint OS is not recognizing internal M.2 SSD while click on Computer icon on desktop?

A:

Have to get into UEFI BIOS and switching SATA settings from RAID to AHCI for the fix.

Note: If you already installed Windows 10 by the RAID configured, then you have to re-install Win10 

after the setup from RAID to AHCI. Otherwise Win10 will keep crashing with BSOD.
