Ok, that purple screen is GRUB, the GRand Unified Bootloader. It is installed in the MBR of your hard disk and it can boot both Windows and Linux distros. The thing I don't understand is how it got somehow replaced by the Windows bootloader. Anyway, to be able to get that dear purple screen again, you need to reinstall GRUB in the MBR.
So, get a bootable USB/CD/DVD of your favourite Linux distro and run it in live mode. Then you mount the partition of your Linux distro, chroot into it and install GRUB:
Code:
# make a mount point
sudo mkdir /mnt/ubuntu
# mount Ubuntu partition (replace X with partition number, e.g. /dev/sda3)
sudo mount -t ext4 /dev/sdaX /mnt/ubuntu
# mount a couple of necessary filesystems
sudo mount -t proc /proc /mnt/proc
sudo mount --rbind /sys /mnt/sys
sudo mount --rbind /dev /mnt/dev
sudo mount --rbind /run /mnt/run
# chroot into Ubuntu filesystem
sudo chroot /mnt/ubuntu env -i HOME=/root PATH=/usr/bin:/usr/sbin:/bin:/sbin bash --login +h
# install grub
grub-mkconfig -o /boot/grub/grub.cfg
grub-install /dev/sda
# exit chroot environment
exit
All the best.
