Cannot install Windows 7 on Dell OptiPlex 7040

Hello,

I bought OptiPlex 7040 module which had Windows 10 Korean version 1 weeks ago. I want to install Windows 7 but it seems to be not work.

My computer has SSD and HDD. When the installation starts, I cannot find the SSD, therefore I select the HDD for installing Windows 7. (I already try this guide en.community.dell.com/.../19669861 but it is not work)

However, the installation process run few seconds and it stop after rebooting.

Could you please tell me how to fix this problem? Thank you
