Installation was successful, I installed it on my laptop which has windows and ubuntu16, created the /boot/efi partition everything looked fine in the installation, but can't load manjaro in grub bootloader which came with the ubuntu (it listed manjaro thereafter I did update-grub from ubuntu), which is not the problem that I am here for.
the issue is i can't access bios menu by pressing f2 which I was able to access before the installation, and im still able to access once if i remove all the newly added partitions, which are root, swap, and the /boot/efi,but im able to choose bootloader by pressing f12 and when if i choose manjaro bootloader its loading manjaro and ubuntu and windows fine, but again missing bios is the issue.
so the issue has to be with manjaro i3 installation.
faced the same behavior when i tried to install this when only windows was there in my laptop.
totally new to manjaro and thanks for the help.
