将 sdbx 分区克隆到 sdax。现在 Ubuntu 从 sdax 而不是 sdbx 启动

我只是想备份一下，现在又这样了。我该如何从 sdbx 启动？

我使用 clonezilla 将分区从内部 SSD 克隆到另一个内部 HDD。

如果你将分区 A 克隆到分区 B

  1. 在计算机上启动实时 Ubuntu 会话
  2. 使用 Gparted 在分区 B 上设置新的 UUID
  3. 在分区 A 上更新 grub
 sudo su
 mount /dev/sd__ /mnt
 mount --bind /dev /mnt/dev
 mount --bind /proc /mnt/proc 
 mount --bind /sys /mnt/sys
 mount --bind /usr /mnt/usr 
 chroot /mnt  
 update-grub (may get an error about not finding a grub drive on the usb)
 grub-install /dev/sd_
 CTRL-D on keyboard.
 umount /mnt/dev 
 umount /mnt/proc
 umount /mnt/sys 
 umount /mnt/usr
 umount /mnt
  1. 更新 B 分区上的 grub
 blkid (copy sd__'s UUID)
 mount /dev/sd__ /mnt
 leafpad /mnt/etc/fstab, fix UUID
 mount --bind /dev /mnt/dev
 mount --bind /proc /mnt/proc 
 mount --bind /sys /mnt/sys
 mount --bind /usr /mnt/usr 
 chroot /mnt  
 update-grub (may get an error about not finding a grub drive on the usb)
 grub-install /dev/sd_
 CTRL-D on keyboard.
 umount /mnt/dev 
 umount /mnt/proc
 umount /mnt/sys 
 umount /mnt/usr
 umount /mnt
  1. 重新启动，应该...

启动到 B 分区系统（可能列为 Debian，PartA 应该是下面的选项）检查正在使用的分区：lsblk，sd__ 是 /

 sudo update-grub
 sudo grub-install /dev/sd_
 reboot

  1. 启动进入 A 分区系统

    检查正在使用的分区：lsblk，sd__ is / 如果这有效，你就完成了
