Debian boot option removed from Grub after update [closed]

I updated Windows 10 on my dual-boot machine, and was met with the grub rescue interface. I had to use the normal.mod to get into Grub and boot Debian, but I ran into some problems after running update-grub as suggested.
First, I got the error /usr/sbin/grub-mkconfig: 253: /usr/sbin/grub-mkconfig: cannot create /boot/grub/grub.cfg.new: Directory nonexistent
So I made the directory, ran it and sudo grub-install /dev/sda and when I rebooted, Grub was both an ugly blue colour and the Debian boot option was gone, with only Windows 10 remaining.
I can get into Debian through the same normal.mod method, but why is this happening? How can I get the Debian boot option back on Grub when the machine boots?
