- With grub installed, the user must still create the menu.

Should I use grub or GRUB2?
Grub2 has become the default bootloader for most Linux distributions. If you need to run Linux on an IoT device, a device with a non-x86 based architecture, or a device with UEFI instead of a BIOS, or a device that requires secure boot, you must use Grub2 as the legacy version of Grub does not support these use cases.
How to set Grub to remember your last selected entry?
Here’s how to set the Grub bootloader so it will remember the last booted item. Open a terminal and enter the following command: sudo nano / etc / default / grub Inside gedit, look for GRUB_DEFAULT=0.
How to save an OS in GRUB 2?
Saving an OS can be achieved by running sudo grub-set-default if DEFAULT=saved is set in /etc/default/grub. It may also be saved if GRUB_SAVEDEFAULT=true is also set in /etc/default/grub. In this case, the default OS remains until a new OS is manually selected from the GRUB 2 menu or the grub-set-default command is executed.
From now on when the user reboots, the Grub menu will be totally hidden unless the “Shift” key is pressed. In some versions of Linux it is possible to update the changes in Grub by running update-grub. Not all Linux distributions support this though, and it is essentially an alias for a longer command.
Is there a way to make Grub load faster?
Grub is useful, but for some, the menu loads way too fast. To change that, look for GRUB_TIMEOUT=5. The default is five seconds. Change this number to anything that sounds like it would be more comfortable (like ten or fifteen, for example). Additionally, if the Grub timeout is way too slow, change it to three seconds for increased speed.
