Hi,

-change boot option to legacy mode and disable secure boot consequently

I think in this part you do not need to turn to legacy, leave it UEFI, only
disable secure boot.

Debian Jessie has support for UEFI boot.

Try reinstall grub using the normal installation cd, in it has an option to
recover or access shell in your installed system.
