The following guide or recipe requires shell access to your FydeOS installation, therefore is assumed to be enabled. If altering system file is required, you will also need to .

GRUB plays a crucial role in FydeOS for PC, particularly in facilitating the silent upgrade feature by switching boot partitions. If you find the GRUB menu appearing at every system boot-up to be bothersome, this guide will help you hide it. We'll achieve this by modifying the grub.cfg configuration file in the EFI directory.

#Step 1: Access the Shell

1. Press ctrl + alt + F2 to open the tty shell interface.
2. Input the username chronos.

#Step 2: Mount the Partition

1. Type sudo su to acquire administrator privileges.

   Note: from FydeOS v17 and openFyde r114 onwards, sudo su will no longer work. Older versions will not be impacted.

2. Input lsblk to verify that your partition 12 is sda12. Adjust this according to your specific situation.

3. Mount the sda12 partition as /tmp/p12 by executing the following commands:

   mount -o remount rw /
   mkdir /tmp/p12
   mount /dev/sda12 /tmp/p12
   

#Step 3: Edit the Configuration

1. Use the following command to open the file:

   sudo nano /tmp/p12/efi/boot/grub.cfg  
   

2. Scroll down to locate set timeout and modify it as shown below:

   set timeout=0
   

   Save the changes by pressing ctrl + x and then typing y.

#Step 4: Reboot the System

Execute the following commands to unmount the partition and restart the system:

umount /tmp/p12
reboot

By following these steps, you can successfully hide the GRUB menu during the boot-up of FydeOS for PC.
