Linux EFI boot order

If after installing Linux Mint in EFI mode, your computer skips the boot menu and boots straight into Windows (or another operating system), you probably have an issue with the boot order.

To modify the boot order:

1. Boot Linux Mint in live mode (with your USB stick or DVD).
2. Open a terminal.
3. Type sudo efibootmgr.

This command lists the available boot options and the boot order.

In the screenshot above, there are three boot options:

• ubuntu at 0000
• linuxmint at 0001
• Mac OS X at 0081

The boot order is 0081. This indicates that the computer only tries to boot Mac OS and not Linux Mint.

Important

For technical reasons Linux Mint uses ubuntu as its EFI boot name.

1. To fix the boot order, type sudo efibootmgr --bootorder XXXX,YYYY (where XXXX and YYYY are the operating system boot options you want to boot).

In the screenshot above, sudo efibootmgr --bootorder 0000,0081 instructs the computer to first try to boot Linux Mint (ubuntu being the EFI boot name for Linux Mint), and then Mac OS.

1. Restart the computer.
