推荐答案

这将是一个糟糕的安全系统，允许你这样做。

It would be a poor security system that allowed you to do this.

第一种方法

使用一个或另一个具有重置密码功能的可启动救援磁盘。其中一个产品是GPL SystemRescueCD：

http：// www.linux-magazine.com/Online/Features/Resetting-Passwords-with-SystemRescueCd [ ^ ]，

https://en.wikipedia.org/wiki/SystemRescueCD [ ^ ]，

http://www.sysresccd.org/ [ ^ ]。



另见列表： https://en.wikipedia.org/wiki/List_of_data_recovery_software [ ^ ]。



准备这样的磁盘，CD / DVD，HD或者提前刷新驱动器（但首先检查计算机的BIOS允许您启动的内容;有时，它只有CD / DVD，有时USB连接的硬盘驱动器工作，但不是闪存驱动器。在这个磁盘上，从上面引用的列表中添加了几个恢复工具，除此之外，它们可以单独启动。



有很多方法可以创建一个多重启动闪存驱动器。我使用YUMI： http://www.pendrivelinux.com/yumi-multiboot-usb-creator [ ^ ]。



我尝试的另一种方式是Rufus;它允许使用EFI，不仅仅是BIOS，但我不确定它是否可以使它成为多重启动，可能不是。

第二种方法

始终拥有其中一个高清基座（ https://en.wikipedia.org/wiki/Disk_enclosure [ ^ ]，同样的事情，但在热插拔底座的形式，您可以插入一个或多个驱动器，而无需使用螺丝刀，这也可以在运行中完成。它实际上也有助于第一种方法，因为并非所有允许从USB启动的BIOS版本都允许从USB闪存驱动器启动，然后您可以快速创建USB或eSATA连接的硬盘驱动器。



如第一种方法所述从其他媒体启动，但是，它可以是任何可启动的基于Linux的发行版，而不是救援磁盘。将所有重要文件备份到另一个硬盘驱动器并重新安装Linux。然后从备份中放回文件。

First method

Use one or another bootable rescue disk which has the feature of resetting passwords. One of such products is GPL SystemRescueCD:
http://www.linux-magazine.com/Online/Features/Resetting-Passwords-with-SystemRescueCd[^],
https://en.wikipedia.org/wiki/SystemRescueCD[^],
http://www.sysresccd.org/[^].

See also this list: https://en.wikipedia.org/wiki/List_of_data_recovery_software[^].

It's a good idea to prepare such disk, CD/DVD, HD or flash drive in advance (but first check up what your computer's BIOS allows you to boot from; sometime, it's only CD/DVD, and sometimes USB-connected hard drive works, but not flash drive). On this disk, put several recovery tools from the list I referenced above, and beyond it, the way they could be booted separately.

There are many ways to create a multiboot flash drive. I use YUMI: http://www.pendrivelinux.com/yumi-multiboot-usb-creator[^].

Another way I tried was Rufus; it allows to use EFI, not only BIOS, but I'm not sure if it can make it multiboot, probably not.

Second method

Always have one of those HD docks (https://en.wikipedia.org/wiki/Disk_enclosure[^], the same thing, but in the form of hot-swappable docks where you can insert one of more drives, without a need to use a screwdriver, which can also be done on the run). It can actually be helpful in the fist method, too, because not all BIOS versions which allow boot from USB allow the boot from USB flash drive, then you can quickly create an USB or eSATA-connected hard drive.

Boot from another media as described in first method, but, instead of rescue disk, it could be any bootable Linux-based distro. Backup all important files to another hard drive and reinstall Linux. Then put back the files from backup.
