# dd if=/dev/sda1 of=/dev/sdb1Copy to Clipboard Copied! Toggle word wrap Toggle overflow 在两个磁盘的第一个分区中更新
prep和boot标志：parted /dev/sda set 1 prep on parted /dev/sda set 1 boot on parted /dev/sdb set 1 prep on parted /dev/sdb set 1 boot on
$ parted /dev/sda set 1 prep on $ parted /dev/sda set 1 boot on $ parted /dev/sdb set 1 prep on $ parted /dev/sdb set 1 boot onCopy to Clipboard Copied! Toggle word wrap Toggle overflow
