在 SCSI1 (0,0,0) (sda) 设备的第 1 分区上创建 ext4 文件系统失败请问该怎 么 解决 >??!! WARNING: partition(s) 1 on /dev/sda could not be modified, probably because it/they is/are in use. As a result, the old partition(s) will remain in use until after reboot. You should reboot now before making further changes. 装系统的无数次 每次在ubuntu里一折腾我就要装一遍系统 我就想要个ubuntu一个系统怎么弄 啊
