현재 하드 UUID 보는 방법은 아래와 같다..
[root@~]# blkid
/dev/sda1: UUID="abda63c5-973f-4981-9e55-5e93eeac9031" TYPE="ext4"
/dev/sda2: UUID="6d5741e5-cbdd-4e84-8638-88e77a444194" TYPE="swap"
새로운 UUID 생성 방법은 아래와 같다
[root@ ~]# uuidgen
2efc628d-a648-4f4a-96af-925f13e1ee70
tune2fs /dev/sda1 -U ****** <- 생성된 UUID 값을 넣어주면 바로 바뀐다.

변경된 UUID 값으로 부팅하고 싶으면 아래 파일 부분에 붉은색 부분을 수정후 저장 한다
