Here is what I did.
Installed manjaro (latest) alongside windows 10.
In my ASUS bios, secure boot is disabled and I selected ‘other os’.
During the install I chose boot/uefi , and allocated 512mb and formatted as fat 32 after flagging it.
All went well. I booted up several times and was able to select manjaro (gnome) and windows, no problem.
I then decided just for the heck of it to also look at manjaro KDE and decide if I wanted to
replace it gnome. But what I did was just view it on the bootable USB. I shutdown, and then rebooted.
On doing so the boot loader disappeared and only Win 10 would boot. I will re-install again, but before I do, I want to ask you guys if you have any ideas as to why this has happened?
Thanks in advance
