Hello

I tried to install Kde neon with a dual boot on windows 8 but failed.

I tried the manual solution and created two new partitions (ext4 40giga and swap 8giga).
Installation was going normally and seemed to be fine but after the reboot I had only the windows option.

I followed every step of this video.

Have you got any idea ?

Thx.

Do you have Grub installed correctly?
