Windows 7 with M.2 SSD storage option
You're trying to run Windows 7 on an MSI M5 Z270 with an M.2 SSD, but Windows isn't recognizing it and instead shows the main HDD. This usually happens when the operating system can't find a compatible drive. You might need to create a bootable USB with Windows 7 or use a recovery media like Windows Installer CD.
Which SSD is it? Some M.2 drives require adding a driver through the Windows Installer before they appear. Also, make sure to disconnect every other HDD or SSD during installation. Windows tends to install the bootloader on the incorrect drive by default. If you plan to replace that second disk later, your system might stop booting altogether.
Intel SSD 600p M.2 6GB requires specific setup steps. Follow the official tutorial for installation and configuration.
Reviewed their downloads area and noticed no driver listed. Likely the issue involves UEFI instead of older BIOs, or vice versa. I’d probably reach out to the motherboard maker to confirm any required settings.
