电脑无法开机，提示&no bootable device&信息，造成此类故障的重要原因是磁盘引导分区信息丢失所造成的，对此我们可以通过以下方法来解决。
1、如果发现电脑机箱上插有U盘或其它可移动磁盘设备，建议暂时将此设备拔出，以便让系统正常选择从硬盘启动。
2、当然，我们也可以选择操作系统引导方法，重启开机并在出现第一画面时，按&DEL&或其它指定键盘按键进入CMOS界面。
3、在进入CMOS设置界面，在&启动类型&选择界面中，选择从&硬盘启动&项，如图所示：
4、如果从硬盘启动失败，则可以利用相关PE工具对引导分区进行修复。例如我们可以利用&U启动&PE工具，在进入桌面后，点击&Windows引导启动修复&工具对引导分区进行修复。
5、当然，我们也可以利用&DiskGenius分区工具&对引导分区进行修复。在其程序主界面中，右击要修复的分区，从弹出的右键菜单中选择&重建主引导记录&项进行修复。
6、当然，我们在利用U启动还原系统时，也会提供&修复引导分区&的选项，只需要勾选即可对引导分区进行修复。

Boot device A boot device is any piece of hardware that can read or contains the files required for a computer to start. For example, a , ,
drive, and
are all considered bootable devices. However, unless the necessary boot files are stored on the drive, diskette, or disc the computer will not be able to boot from that device.
Additional information

When an operating system such as Microsoft Windows installed onto the hard drive it copies the boot files and drivers required to load Windows on the computer. When installing a new operating system, troubleshooting the computer, or booting from another drive such as the CD-ROM drive, a bootable disc or setup disc is inserted into the drive. If the

and the bootable disc is inserted the computer it will load from the disc instead of the hard drive.
No boot devices available
If the computer hard drive is not working, has not yet been setup, or there are no other bootable devices you will receive an error when the computer boots. Common errors in this situation are &no bootable device& or "no boot devices available". This error is an indication that the computer looked at all available devices, but did not see any drive with boot files. If the computer was working before getting this error message and no any new
has been added, it's very likely that your
has failed.
However, before assuming the hard drive has failed make sure no cables (especially USB cables) are connected to the computer and that all diskettes, CD's, and any other USB devices are disconnected from the computer. In some situations, the computer may be trying to boot from a non-bootable device.
If there are no other disks, discs, or USB drives connected to the computer and you have recently moved the computer you may also want to
and verify that the cables are properly connected to the hard drive.
If none of the above steps help resolve the problem unfortunately it is likely a bad hard drive.
