Booting from a Windows 11 USB drive is an essential skill for installing a clean copy of Windows, repairing startup problems, upgrading hardware, or recovering a system that no longer boots properly. After creating a bootable Windows 11 USB drive, you must configure your computer to start from the USB device instead of the internal storage drive.
Whether you are using a laptop or desktop PC, most modern systems allow USB booting through the Boot Menu, BIOS, or UEFI firmware settings. Understanding how these options work can help you quickly access the Windows 11 installation and recovery environment whenever needed.
In this guide, you will learn how to boot from a Windows 11 USB drive on most computers, including the steps for accessing the Boot Menu, changing boot priority in BIOS or UEFI, and troubleshooting common USB boot issues.
Why Boot from a Windows 11 USB?
There are several situations where you may need to boot from a Windows 11 USB drive:
- Install Windows 11 on a new PC
- Perform a clean Windows installation
- Repair startup problems
- Access Windows Recovery Environment
- Upgrade or replace a hard drive
- Recover files from a non-booting system
Using a bootable USB is often the fastest and most reliable method for Windows installation and recovery.
Requirements Before You Start
Before attempting to boot from a Windows 11 USB, ensure you have:
- A bootable Windows 11 USB drive
- A computer that supports Windows 11
- Access to BIOS or UEFI settings
- A keyboard connected to the system
- Backup copies of important files
If the USB drive was not created properly, the computer may fail to detect it during startup.
Step 1: Insert the Windows 11 USB Drive
Insert the bootable Windows 11 USB drive into an available USB port.
For best compatibility:
- Use a USB 3.0 port if available
- Connect directly to the motherboard ports on desktop PCs
- Avoid using USB hubs during installation
Leave the USB connected before powering on the computer.
Step 2: Restart or Power On the Computer
Restart the computer if it is already running.
If the computer is turned off:
- Insert the Windows 11 USB drive.
- Press the Power button.
- Immediately begin pressing the Boot Menu key.
Timing is important because the boot menu is only available during startup.
Step 3: Open the Boot Menu
Most computers allow you to choose a temporary boot device through the Boot Menu.
Common Boot Menu keys include:
| Manufacturer | Boot Menu Key |
|---|---|
| Dell | F12 |
| HP | F9 |
| Lenovo | F12 |
| Acer | F12 |
| ASUS | Esc |
| MSI | F11 |
| Gigabyte | F12 |

Press the appropriate key repeatedly immediately after turning on the computer.
Step 4: Select the Windows 11 USB Drive
After opening the Boot Menu:
- Locate the USB device in the list.

- Press Enter.
The USB may appear as:
- UEFI: USB Device
- Windows Boot Manager
- Kingston USB
- SanDisk USB
- Generic Flash Disk
Always choose the UEFI version when available for modern Windows 11 installations.
Step 5: Access BIOS or UEFI if Necessary
If the USB drive does not appear in the Boot Menu, enter BIOS or UEFI settings.
Common BIOS keys:
- Delete
- F2
- Esc
- F10
The correct key varies by motherboard manufacturer.
Inside BIOS or UEFI:
- Navigate to the Boot tab.
- Locate Boot Priority.

The computer should restart and boot from the USB drive.
Step 6: Wait for Windows Setup to Load

At this point, the Windows 11 installer is running from the USB drive.
You can now:
- Install Windows 11
- Repair your computer
- Open recovery tools
- Access Command Prompt
- Restore system images
Step 7: Begin Installation or Recovery
Choose the option that matches your goal.
For a new installation:
