Hi: For this installation I created a usb installer using unetbootin, as it was recommended on the elementary website. The installation (having elementary alongside Win 10) seemed to work ok. At the end the process told me to restart, but when I did, it stared to Windows. The grub bootloader didn't show. Will appreciate suggestions to troubleshoot this problem. Thanks.
Found a solution: In Windows, go to the menu and search for Command Prompt, right click on it to run it as administrator Copy paste the command below: bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi
