Consegui resolver, a solução foi ter baixado a mesma versão do versão do
Debian, dar boot pelo DVD e entrar no modo rescue, eu achei bem intuitivo
aquilo, eu pensei que era pra digitar linha de comando, mas não foi assim,
o modo rescue restaura com criptografia e tudo, se for ver nem era preciso
usar a live cd, o grub foi restaurado pro estado que estava antes de
instalar o Windows 10, ou  seja aparecia no grub o Windows 7, mas nada que
um update-grub no Debian não resolvesse, está tudo ok agora.

Que alivio em saber que recuperei meu sistema, e meu windows está
atualizado, obrigado a todos por tudo e desculpe o incomodo.

Pra quem pode sofrer com isso, restaurar no modo rescue tem que ter noção
de qual é a partição raiz, qual partição instalar o grub e por ai vai, a
parte da live cd me ajudou um pouco a pegar a noção disso.
