Currently Dual booting Ubuntu 18.04.3 and Windows 10, however I realized a bit too late that I put my Ubuntu installation only on my HDD, making it a bit slow/laggy. I'd like to migrate the installation onto my SSD for the faster boot time and general responsiveness and whatnot without having to reinstall Ubuntu all over again, while keeping most of the contents such as general files and applications on my HDD due to my small SSD size. Is there a way to do that?
Alternatively, if my only option is to reinstall, is there a way to remove the Ubuntu installation without having to fix the boot loader? I don't have an optical drive in my device and don't have access to any flash drives for the time being. Note that it's a UEFI system, so in theory I should just be able to move the Windows boot loader to the top and simply re-do the installation of Ubuntu in the appropriate drives, right?
