我购买了一个 vps，但我忘记了它的服务器 rootpassword。我尝试通过救援模式重置它，但在安装级别失败：
root@rescue:~# mount -o rw /dev/sda1 /mnt
mount: /dev/sda1 is write-protected, mounting read-only
NTFS signature is missing.
Failed to mount '/dev/sda1': Invalid argument
The device '/dev/sda1' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
root@rescue:~# mount -o rw /dev/sdb1 /mnt
mount: /dev/sdb1 is write-protected, mounting read-only
NTFS signature is missing.
Failed to mount '/dev/sdb1': Invalid argument
The device '/dev/sdb1' doesn't seem to have a valid NTFS.

这是 fdisk -l 的输出：
