Grub2-reboot # FreePBX Distro 7에서는 사용할 수 없음 - CentOS 7 기반

동일한 구성을 사용하고 CentOS 7에서 "grub2-reboot # && restart"를 통해 부팅하는 두 번째 메뉴 항목을 성공적으로 추가했지만 다음에 FreePBX Distro 7 메뉴 항목 선택을 실행할 때 아무 것도 변경되지 않는 것 같습니다.

문제 해결/테스트/수정을 시도하는 방법에 대한 아이디어가 있습니까?

또한 다음을 시도했지만 동일한 결과를 얻었습니다.

sudo rm /boot/grub2/grub.cfg
sudo rm /etc/grub.d/* -R
sudo rm /etc/sysconfig/grub
yum reinstall -y grub2-tools
grub2-mkconfig -o /boot/grub2/grub.cfg
grub2-install /dev/sda

따라서 FreePBX는 자체 Repo를 사용하므로 위의 코드를 따랐지만 grub2-tools를 수동으로 다운로드했는데 이제 다음 오류가 발생합니다.

[root@freepbx grub]# grub2-install --target=x86_64
