📖Grub menu 30 sec

Grub menu stays 30 seconds before the system starts

You may have noticed that every time during OS boot, the GRUB menu appears first and stays on your screen for 30 seconds.

This can be useful in rare cases, but it is not necessary in everyday use, especially since this GRUB menu stays for half a minute and you need to hit Enter to go on quicker.

Here is the related issue, and below you can see the solution.

To remove this thirty-second GRUB meditation, do the following:

1. Open /etc/default/grub as admin.

2. Add GRUB_RECORDFAIL_TIMEOUT=0 to the file and save changes.

Added GRUB_RECORDFAIL_TIMEOUT=0 to the GRUB file

1. In the Terminal, run sudo update-grub

2. Reboot.

If you need the 30 sec GRUB menu again, repeat the procedure above but delete the GRUB_RECORDFAIL_TIMEOUT=0 string you added at step 2.
