Title: How to set up a USB disk to boot
In today's digital age, USB boot has become a common method for installing operating systems, repairing system failures, or running portable software. This article will introduce in detail how to set up USB disk booting, and provide structured data to help you quickly master the steps.
1. Preparation work

Before setting up a USB flash drive to boot, make sure the following conditions are met:
| Project | request |
|---|---|
| U disk capacity | At least 8GB (more than 16GB recommended) |
| operating system image | ISO file (such as Windows 10/11, Linux distribution) |
| Tool software | Rufus, UltraISO or Ventoy |
| Computer support | The motherboard needs to support UEFI or Legacy boot mode |
2. Make a bootable USB disk
The following are the steps to use the Rufus tool to create a bootable USB flash drive:
| steps | Operating Instructions |
|---|---|
| 1 | Download and run Rufus (administrator rights required) |
| 2 | Insert the USB flash drive and the software will automatically identify the device. |
| 3 | Select the ISO file and set the partition type (MBR/GPT) |
| 4 | Click the "Start" button and wait for completion (about 5-15 minutes) |
3. Set the BIOS/UEFI boot sequence
The entry methods for different brands of motherboards are slightly different:
| Motherboard brand | start button | Remarks |
|---|---|---|
| ASUS | F2 or DEL | Some models need to press ESC |
| Dell | F12 | quick launch menu |
| Lenovo | F1/F2 | For ThinkPad series, press Enter |
| HP | F9/F10 | Commonly used ESC on desktop computers |
4. Solving common problems
| Problem phenomenon | solution |
|---|---|
| U disk cannot be recognized | Check whether the USB interface is damaged and try to replace the port |
| Black screen after startup | Re-create the boot disk to ensure the ISO file is complete |
| Prompt "Missing OS" | Turn off the Secure Boot function in the BIOS |
| Slow startup | Use USB 3.0 interface and high-speed USB flash drive |
5. Things to note
1. Back up the U disk data before operation. The U disk will be formatted during the production process.
2. Some old computers need to turn on "Legacy Support" in the BIOS.
3. Apple Mac devices need to select the USB flash drive through the startup manager (Option key)
4. It is recommended to use the original system image to avoid security risks caused by the modified version.
Through the above steps, you have mastered the complete setup method of USB boot. If you need more help, please refer to the motherboard manual or visit the manufacturer's technical support website. If you encounter problems in actual operations, you can also search for solutions on technical forums such as CSDN, Zhihu and other platforms.
