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
DELL-Jesse L
