no bootable device

detected. What should I do?

If your computer is displaying the message "no bootable device detected", it means the computer is unable to find a device containing the operating system to start up. There are a few potential solutions to this problem:

1. Check to make sure that there are no external storage devices (such as USB drives or CDs) plugged into your computer. Sometimes the computer will try to boot from these external devices instead of the internal hard drive.

2. Check the BIOS settings to make sure that the correct boot order is set. The BIOS is the program that controls the hardware on your computer, and the boot order is the sequence of devices that the BIOS will attempt to start up from. Typically, the internal hard drive should be listed first in the boot order.

3. Check to make sure that the hard drive is properly connected to the computer. Sometimes the hard drive can become loose or disconnected for various reasons, which can cause the "no bootable device" error.

4. If none of these solutions work, you may need to repair or replace the hard drive itself.

no bootable device 修复

"no bootable device"通常是一个错误消息，当你尝试启动电脑时遇到，这意味着计算机无法从安装在启动设备（如硬盘、USB驱动器或光盘）上找到可用的操作系统来引导。这可能是由于以下几个原因：

1. **硬盘问题**：硬盘可能出现坏道或分区表损坏，导致操作系统找不到启动位置。
2. **启动设备损坏**：外部设备（如U盘或CD/DVD）可能已损坏，或者未正确插入或损坏。
3. **BIOS设置问题**：BIOS（基本输入输出系统）配置不当，没有正确识别默认启动设备。
4. **系统文件丢失**：如果引导扇区被病毒攻击或意外删除，也可能导致此问题。

要修复这个问题，你可以按照以下步骤操作：

- **检查连接**：确保所有硬件设备都正确连接并且工作正常。
- **恢复启动顺序**：进入BIOS设置，确保首选启动设备是正确的。
- **数据恢复**：如有必要，尝试使用数据恢复工具找回损坏的引导扇区或系统文件。
- **重新分区或重建MBR**：对于硬盘问题，可能需要重新分区或重建主引导记录（Master Boot Record, MBR）。
- **从安全模式安装系统**：如果能进入安全模式，可以尝试修复启动项或从其他媒体重新安装系统。
