This question already has an answer here:
I've installed Ubuntu 15.10 Mate edition perfectly fine. I've created a swap, root, home partition and I've used the 100MB partition that Windows create as the efi partition.
Everything seems to work fine, except the moment I boot into windows. For some reason my computer doesn't seem to boot into grub anymore, but straight into Windows.
I've look into my uefi bios to look for the boot order. at first it said Ubuntu, but now it says Windows Boot Manager.
I am clueless at the moment, maybe you guys could help me.
