How To Ensure rEFInd Menu Shows on Dual Mac/Ubuntu Machine

Ubuntu 13

In today’s world, many users prefer to have dual or multiple operating systems on their machines. This is where rEFInd, a boot manager for EFI and UEFI computers, comes into play. It provides a graphical interface for users to choose which operating system to boot. This article will guide you on how to ensure the rEFInd menu shows on a dual Mac/Ubuntu machine.

Quick Answer

To ensure the rEFInd menu shows on a dual Mac/Ubuntu machine, you need to install rEFInd and set it as the default boot manager using the efibootmgr command in Ubuntu. Additionally, you can modify the refind.conf file to skip the GRUB entry and boot directly into Ubuntu.

What is rEFInd?

rEFInd is a fork of the rEFIt boot manager. It’s designed to automatically detect all the bootable EFI partitions in your system, providing a direct boot option for each. This makes it a popular choice for systems with multiple operating systems.

Installing rEFInd

Before we proceed, ensure that rEFInd is installed on your machine. If not, you can download it from the official rEFInd page. Follow the installation instructions provided for your specific operating system.

Setting rEFInd as Default Boot Manager

Once rEFInd is installed, you need to set it as the default boot manager. This can be done using the efibootmgr command in Ubuntu.

Understanding efibootmgr

efibootmgr is a utility that manages UEFI boot entries. It allows you to create, delete, and modify boot entries.

The -v option is used to display detailed information about each boot entry, while the -o option is used to change the boot order.

Checking Current Boot Order

To check the current boot order, open a terminal in Ubuntu and run the following command:

sudo efibootmgr -v

This command will display a list of boot options with their corresponding numbers. For example, you might see something like this:

BootOrder: 0001,0080,0000

In this example, Ubuntu (Boot0001) is set to boot first, followed by Mac OS X (Boot0080), and then opensuse (Boot0000).

Changing the Boot Order

To set rEFInd (Boot0080) as the first boot option, use the following command:

sudo efibootmgr -o 0080,0001,0000

This command sets the boot order to Boot0080,Boot0001,Boot0000, prioritizing rEFInd. Replace 0080, 0001, and 0000 with the correct boot numbers for your system.

After running the command, reboot your system. rEFInd should now appear as the default boot option.

Modifying rEFInd Configuration

If you want to boot directly into Ubuntu without seeing the rEFInd menu, you can modify the refind.conf file.

Locating and Opening refind.conf

The refind.conf file is located in the /boot/efi/EFI/refind/ directory. Open it with a text editor using the following command:

sudo nano /boot/efi/EFI/refind/refind.conf

Modifying refind.conf

In the refind.conf file, look for the dont_scan_dirs or dont_scan_files option. Uncomment the line (remove the # at the beginning) and add the path to the GRUB entry. For example:

dont_scan_dirs +, /EFI/ubuntu

This command tells rEFInd not to scan the specified directories, effectively hiding them from the boot menu.

Save the changes and reboot. Now, rEFInd will skip the GRUB entry and boot directly into Ubuntu.

Conclusion

In this article, we’ve covered how to ensure the rEFInd menu shows on a dual Mac/Ubuntu machine. We’ve discussed how to set rEFInd as the default boot manager, and how to modify the rEFInd configuration to control which entries appear in the boot menu. Remember to replace the boot numbers and paths with the correct ones for your system. With these steps, you should be able to customize your boot process to fit your needs.
