How to change BIOS settings to install Windows from USB
Jun 28, 2025 am 12:12 AMTo install Windows from a USB drive, the first step is to enter the BIOS to adjust the startup sequence. 1. The shortcut keys for computers from different brands of computers to enter the BIOS are different. For example, press F2 or Esc for Dell, press F10 for HP, press F10 for Lenovo for F1 or F2, press Del for ASUS, press F2 or Del for Acer; 2. After entering the BIOS, find the "Boot" tab, set the USB drive as the first boot item, which may be displayed as "USB Storage Device" or brand name; 3. If the USB drive is not recognized, you need to check the connection, close the "Fast Boot" and confirm that the hard disk mode is set correctly. It is recommended to use UEFI mode with the GPT partition table; 4. It is recommended to plug the USB drive into the USB port behind the host to ensure stable recognition. After completing the settings, save and exit, you can successfully start the installation system from the USB flash drive.
To install Windows from a USB drive, the first step is to enter the BIOS to adjust the startup sequence, so that the computer can be booted from the USB drive first. This matter sounds a bit technical, but it is not difficult to operate. The key is to find the right location.

The right time to enter the BIOS
Different brands of computers enter the BIOS slightly different ways, and common buttons include F2, Del, Esc, F10 , etc. Generally, when the boot screen just appears, it will prompt which key to enter the setting interface. If you miss the time point, you have to restart and do it again.

- Shortcut keys corresponding to common brands:
- Dell: F2 or Esc
- HP: F10
- Lenovo: F1 or F2
- ASUS: Del
- Acer: F2 or Del
It is recommended to start pressing the corresponding key immediately after the computer is turned on, and don’t wait until the system is loaded before starting.
Adjust the startup order (Boot Order)
After entering the BIOS, find the "Boot" or "Start" tab. The startup sequence here determines which device to try to start from when the computer is powered on. You need to move the USB device (usually displayed as "USB Storage Device" or your USB drive brand name) to the first place in the boot order.

A few things to note:
- If the USB device cannot be found, make sure the USB drive has been plugged in and the BIOS supports identification from this interface.
- Some motherboards may list the USB drive as "Removable Device" instead of "USB".
- Some motherboards need to turn off the "Fast Boot" function, otherwise they may skip the USB device and boot the system directly.
Remember to save and exit after modification, usually press F10 and select Yes to confirm.
Ensure hard disk mode is compatible with the installation process
Another thing that is easily overlooked is the working mode of the hard disk, which can generally be found in "Advanced" or "Storage Configuration". It has two common options:
- UEFI mode GPT partition table
- Legacy mode MBR partition table
If you are using a newer system image (such as Win10/Win11), it is recommended to use UEFI mode, and ensure that the USB drive is also made in UEFI. If you encounter a situation where the hard disk cannot be recognized while installing the system, it is likely that this setting is wrong.
There are also some considerations for plugging in the USB port
Although it is OK to plug in any USB port in most cases, sometimes old motherboards only recognize certain interfaces. It is recommended to plug it into the USB port behind the host first, because they are usually connected directly to the motherboard, and the identification is more stable. If you use the USB 3.0 port on the front panel but it doesn't respond, you might as well try it later.
Basically these operations are just the ones, not complicated but easily overlooked. As long as the BIOS is set correctly, you can successfully enter the Windows installation interface.
