Ubuntu keeps showing up in the boot even after deleting it

Heyo,
Like the title says, ubuntu keeps showing up on the boot menu even after I
have deleted the partition it was on (I was dual booting it with windows
8). I google'd a bit and found out I had to download a program called
EasyBCD and with it removing the ubuntu option in the boot list. So I did
all of that but it still shows up on the boot menu (and in the boot
options in EasyBCD). This may also be the reason I cannot install Debian
on my laptop, something I have been trying to do for 4 days now (debian
doesn't show up on the boot meny, even after a succesful installation).
If someone can tell me what is wrong, that would be beautiful.
Thanks.
