I initially had Manjaro installed in UEFI mode. I then used a Ubuntu live USB to install Ubuntu on a new separate partition. I choose the default options and it seems that it has not installed it in UEFI mode.
To boot into Ubuntu I need to change the bios settings to use the legacy boot order and then back to UEFI when I want to boot into Manjaro.
When I'm in legacy boot mode grub does ask if I want to boot Manjaro but when I choose this option I get 'Operation system not found'.
What would be the best method of rectifying this? Should I start from scratch?
