## Grub ##

Grub is the bootloader in most Linux distros that manage the operating systems installed in a computer. If you have installed multiple operating systems like for instance, you have a dual-boot PC running Microsoft Windows and Ubuntu. You should see both entries during the boot process.

## Editing Grub to delete the entries in Ubuntu ##

Install Grub Customizer directly:

sudo pacman -S grub-customizer

After installing, Search for it in the app menu.

Look through the right-click menu for the “Remove” button to instantly delete the menu entry from your Grub bootloader list. Repeat this process to remove other ones too, if necessary.

Then, locate the “Save” button and select it to save the changes you’ve made to the menu system. When everything is saved, close the app.

## Updating Grub ##

Now that the broken Grub entries are removed, the Grub bootloader needs to be updated to reflect the changes. To do this, follow the commands below.

sudo grub-mkconfig -o /boot/grub/grub.cfg

With Grub up to date, reboot your Linux PC. As your Linux PC starts back up, you’ll notice that the changes made to the Grub bootloader have been saved, and the entries you’ve removed should no longer be there in the boot menu.
