I think that my situation is a bit tricky but I am not used to this kind of operations so I could make some mistakes and I apologise.
A week ago I had a dual boot, with GRUB that was installed on the SSD (so it started faster). When booting, I used to chose between Ubuntu 17.04 (Installed on a partition of an HDD, that has MBR) and Windows 10 (Installed on the SSD, NOT MBR).
Now I have reinstalled Windows and GRUB is not there anymore, since I wiped the drive. I would like to restore that dual boot, I tried from a live version of Ubuntu with disk-repair tool but I did not managed to. I don't know what to do and I hope someone has got some clues.
Thanks in advance for reading this.
