I need your support on showing me how to remove correctly Manjaro from a dual boot BIOS computer, the correct way.
Here is my situation. I installed Manjaro on BIOS System using a separate boot partition (not the WIN7 one) on my VM.--->See screenshot with my partitions.
My first try to remove: Start Manjaro Live CD and use Gparted, but here no format of my Manjaro HOME/ROOT/SWAP partitions was possible (some error saying that they are mounted). Din´t work!
My second try to remove: I read a post, that to remove Manjaro all I have to do is log in to Windows, Disk management...delete the partitions. this is what I did, an I got a Grub error (see first Screenshot). Than I got the "grub rescue> screen..so I messed up!
The reason I want to know is that I would like to install Manjaro 16.1 XFCE on the computer of a friend (separate boot partition from Win) so he can try it, learn more about Manjaro and if he doesn't like just format the partitions, without the win7 boot being touched.
Everything is momentarily being tested in VirtualBOX, but I don´t want to install for real till we don´t know to test a correct removal of Manjaro without loosing windows.
Your support is appreciated in advance...
