Linux 下烧制系统启动盘就简单很多了

1. U盘位置

sudo fdisk -l
Disk /dev/sda: 238.5 GiB, 256060514304 bytes, 500118192 sectors
Disk model: SanDisk SD8TN8U2
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: 1F62D7CF-0EF1-453C-A0DB-C0E13E3D6C24

Device         Start       End   Sectors  Size Type
/dev/sda1       2048 125831167 125829120   60G Linux filesystem
/dev/sda2  125831168 126445567    614400  300M EFI System
/dev/sda3  126445568 466184191 339738624  162G Linux filesystem
/dev/sda4  466184192 500118158  33933967 16.2G Linux swap

Disk /dev/sdb: 28.7 GiB, 30752000000 bytes, 60062500 sectors
Disk model: Ultra USB 3.0   
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x00000000

Device     Boot Start      End  Sectors  Size Id Type
/dev/sdb1          32 60062499 60062468 28.7G  c W95 FAT32 (LBA)

/dev/sdb1 则是我的U盘

如果U盘被自动挂载，使用umount 先卸载它

sudo umount /dev/sdb1

开始烧制

sudo dd bs=4M if=镜像路径 of=U盘盘符 status=progress oflag=sync

使用dd命令直接将将iso文件数据写入U盘，所以U盘不包含一个标准的分区表，从而导致系统无法正常的识别其大小，也无法正常使用，使用它安装系统后，如果不需要U盘安装盘了， 可以回复它， 具体的恢复方法有需要再总结一下
