Please advice.
Lenovo B575e notebook.
I need to install Windows 7 to factory preinstalled Windows 8 Lenovo UEFI laptop.
Installation media W7 Pro OEM DVD from internal DVD drive.
Likely there is no need to restore Windows 8 later - so just a clean Windows 7 installation.
Is it correct just to Disable Secure boot in Bios?
Or is there something else requirements?
