Hello, I have installed Windows 10 Pro in UEFI mode in my SSD and I created another partition of my HD (1TB HD) of 250GB to install Windows 8.1 Pro, is it possible to install? Does it have to be in UEFI mode too?
Edit.: I created the bootable pen drive in GPT mode for UEFI, but when I go in BIOS override and select the UEFI pen drive, there is a black screen and then it returns me to the BIOS again, why is that?
