          The file /etc/default/grub contains a line:



          GRUB_TIMEOUT=10 


          edit the file and make the 10 a 0 to hide the grub menu. You may force the grub menu by holding down a key, shift or tab.



          Making Windows the default may be done by renaming the file

          /etc/grub.d/30_os-prober to /etc/grub.d/06_os-prober, so it gets run before the 10_linux file.



          sudo mv /etc/grub.d/30_os-prober /etc/grub.d/06_os-prober

          • This may not work for multi-boot environments, os-prober will reset GRUB_TIMEOUT to 10 if more than one OS is found. See askubuntu.com/questions/117525/… . The default OS could be set with GRUB_DEFAULT instead of renaming files in /etc/grub.d although that is possible.

          • @PRATAB I don't think it will work, see the link I provided. There are a few lines in /etc/grub.d/30_os-prober which will reset the timeout to 10 seconds if more than one OS is found.
