First of all I'm very new in the linux world so please be as tolerant as you could. I try to be as clear as I could in order to explain my question.
My problem: I had 2 OS with dual boot in my laptop, win8 and manjaro. Everything was fine until win8 try to upgrade itself to win10. I have to tell you that, it was a mistake. I was playing with a game in full screen mode and somehow the upgrade starts itself and I haven't noticed it. So the win10 upgrade was succesfull. But it has some problem with the grub...
I solved the problem with this answer: https://askubuntu.com/questions/654386/windows-10-upgrade-lead-into-grub-rescue
And I also tried this: https://forum.manjaro.org/t/grub-error-no-such-partiton/3637/8
Unfortunately i can't fix my grub and I want to change the Manjaro distro to an Ubuntu Gnome.
So my main question is: If I use an Ubuntu live cd and install Ubuntu on the partiton where the Manjaro is now, will it fix the grub and the booting problem with Win10?
Thank you for your guidance and help in advance!
