Possibly, though not likely. What does 'dpkg -l | grep grub' show now?

You had more files when you were using Grub. Now you surely have Grub2, which 
scatters files across more locations instead of keeping most in /boot/grub.

I have no "dual boot" systems, but I do have *dozens* of multiboot systems 
representing hundreds of installations of various distros that include 
Wheezy, Jessie and Stretch. Grub is installed to the MBR of none of them, 
regardless whether or not Windows or DOS are among their installations.

Several different ways work here. This machine:
1-Generic code is installed to MBRs
2-/dev/sda1 and /dev/sdb1 are marked active/bootable in MBR table
3-Grub actually used for booting is installed to /dev/sda1 and /dev/sdb1
4-After installation or kernel update, I copy kernel and initrd to /dev/sd#1
5-Grub loads kernel/initrd from /dev/sd#1
6-/dev/sd#1/boot/grub are maintained entirely by myself
7-/ partitions are on /dev/md1, /dev/md2, /dev/md3 & /dev/md4 (md4 running)

The method is fundamentally equivalent to how DOS, OS/2 and Windows boot: 
standard MBR code finds the active/bootable partition, then loads and 
transfers control to the boot code found there.

A very different, and simpler, example can be found on:

 From the one from which I write this (but note it's not the location from 
which machine normally "boots", only the one the distro installation installs 
and maintains):
# ll /boot/grub
