Adjusting the Global Configuration

-

You can adjust many of rEFInd's options by editing its refind.conf file. You can use any text editor you like for the job, but be sure it saves the file in plain ASCII text, not in a word processing format. (In theory, a UTF-16 encoding should also work, but I've not tried that myself.) Note that the EFI shell includes its own editor. If you need to make a change before you launch an OS, you can launch a shell, change to the rEFInd directory, and type edit refind.conf to edit the file. This EFI editor is quite primitive, but it gets the job done. After editing, you'll need to reboot for rEFInd to read the changed configuration file.

You can adjust many of rEFInd's options by editing its configuration file. This file is called refind.conf by default; but you can use another filename by passing -c filename as an option, as in refind_x64.efi -c myrefind.conf to use myrefind.conf in rEFInd's main directory. You can specify a configuration file in another directory, but to do so, you must use backslashes as directory separators, as in -c \EFI\other\refind.conf. This feature is intended for users who want to have rEFInd appear in its own menu, with the version launched in this way behaving differently from the original—for instance, to have a secondary rEFInd that provides boot options hidden by the main one. In this scenario, the default refind.conf would have a manual boot stanza defining the new rEFInd instance, including its -c option.
