Ubuntu – Install Ubuntu first before installing Windows for dual boot


Am i able to install ubuntu first and then install windows? I allocated ubuntu 15gb and im going to load the rest (900gb) for windows but will grub loader work? Or do i have to install windows first and then ubuntu? Thanks

Though you can technically install Ubuntu and Windows in any order, I would highly recommend that you install Windows first. This is because installing Windows on top of Ubuntu will likely result in messing up the MBR. When that happens, it can be very difficult to boot into Ubuntu, because the Grub dual-boot menu might disappear. It can be a little tricky recovering from that, which you can read all about here:

So if you have the opportunity to start from scratch, installing Windows first and Ubuntu second could potentially make your life MUCH easier.
