在启动应该成为Windows 8.1操作系统的虚拟机时，如何访问/启动/通过特定分区（在本例中为Lenovo Recovery分区）？

原始磁盘布局

ThinkPad X1 Carbon 2nd Gen.在其原始磁盘布局中拥有一个恢复分区。例如，在型号20A7005RGE中，磁盘布局的结构如下：

• sda1：ntfs，WINRE_DRV，~1GB
• sda2：fat32，SYSTEM_DRV，~260MB
• sda3：未知，Microsoft保留分区，~128MB
• sda4：ntfs，Windows8_OS，~217GB
• sda5：ntfs，Lenovo_Recovery，~14GB
• sda6：未知，基本数据分区，~7GB [/ list]

另请参阅http://users.wfu.edu/yipcw/lenovo/2014/X1C2/：阅读OEM Softare部分中的磁盘布局。

重要分区的克隆

我使用dd保留了每个重要分区的克隆。举例来说，对于sda1，我指示： dd if=/dev/sda1 of=/mnt/usb/WINRE_DRV.dd并且类似地完成其余的（除了sda3和sda4）。

创建虚拟磁盘

主要用于硬件测试（即移动宽带调制解调器），以及一些软件，我试图从VirtualBox中的恢复分区安装Windows（8.1）。为此，我在虚拟磁盘中重新创建了原始磁盘布局。注意，分区大小是从原始磁盘布局中提取的（如上所述），并且注意选择适当类型的分区（NTFS，Windows Recovery Environment，EFI等）。

# create sparse image
dd if=/dev/zero of=ThinkPad_Recovery.img bs=1 count=0 seek=256G

# re-create partitioning scheme as root
fdisk ThinkPad_Recovery.img

# OR
gdisk ThinkPad_Recovery.img

# access partitions contained in image via /dev/loop*?
partx -a ThinkPad_Recovery.img

确认虚拟磁盘的布局

# check...
fdisk -lu ThinkPad_Recovery.img

克隆虚拟磁盘内的原始分区

# copy content of dd-ed partitions into corresponding partitions inside the virtual disk 
dd if=WINRE_DRV.dd of=/dev/loop1p1
dd if=SYSTEM_DRV.dd of=/dev/loop1p2
dd if=Lenovo_Recovery.dd of=/dev/loop1p5
dd if=Basic_data_partition.dd of=/dev/loop1p6

# device mappings removed after rebooting!

只是要确定...

到现在为止还挺好。转换。img into。vdi通过VBoxManage convertfromraw ThinkPad_Recovery.img ThinkPad_Recovery.vdi --format VDI并使用这个新的虚拟机，似乎工作。

但是，启动机器后的屏幕是：。

似乎没有访问实际的恢复分区（以“Lenovo_Recovery”命名）。我该怎么办？
