How was Windows installed initially - if it was installed in UEFI mode and you are attempting to boot Debian in legacy mode, it will fail and vice versa. What had you installed previously using Grub? Are you booting from a USB stick? How did you write the Debian image to the USB stick? Do you know what firmware your system is likely to need? Getting a Windows system to dual boot Debian is (relatively) straightforward but knowing the answer to some of the above questions may help us narrow down useful suggestions as to what to try next.
