Not sure how to explain this, but a friend installed Manjaro on a USB Hard drive, but still has Windows installed on his main drive, but he wants to have it so his system boots into Manjaro automatically, but not sure how to do that since grub doesn't appear at boot.
What he is currently doing is just booting into windows, going into advanced boot options once booted in, and clicking use a device and then booting into Manjaro that way
Is there anyway to get grub at boot to select manjaro there and not have to boot into Windows? In the boot priority in bios, these are the only options he gets, and "USB Hard disk" just tells him "No media detected"
Any help is greatly appreciated!
