Have a newer Acer laptop which can accept Windows 10 installation. Laptop currently dual booted with Windows 7 Home Premium and Ubuntu 14.04 Is it better to install Windows 10 and then use Boot Repair to fix any problems with already installed Ubuntu 14.04 OR should I uninstall and reinstall Ubuntu after I have installed Windows 10? Thanks in advance.
You can do either order, but what matters is making sure you don't wipe another install to install an OS. I would do Win10 then boot repair if it were me.
