It is not difficult to boot from a USB flash drive when installing Windows 10. The key is to prepare well and have clear steps. First prepare a USB drive with at least 8GB capacity, and download the ISO image file for Windows 10, and use Rufus or Microsoft's official Media Creation Tool to write the ISO file to the USB drive. Pay attention to selecting the correct ISO file and target USB drive to avoid misformatting other devices. Then plug in the USB flash drive and restart the computer and enter the BIOS or UEFI setting interface, set the USB flash drive as the first boot item, and turn off the "Fast Boot" function. After entering the installation interface, select the language, time and keyboard input method, click "Install Now", enter the product key or activate it later. When selecting the installation type, it is recommended to select Custom Installation, then select the installation location and format or partition the hard disk. Click "Next" to start copying the file. The whole process takes about 20 to 40 minutes. After the installation is completed, check whether the driver is complete, update Windows Update, and check the system activation status.

It is actually not difficult to boot from a USB flash drive when installing Windows 10. The key is to prepare well and have clear steps. Just make the USB drive into a bootable installation disk and set the startup sequence of the computer, and the installation can be completed smoothly.

Prepare an available installation USB drive

First of all, you have to have a USB drive with at least 8GB capacity. It is recommended to use USB 3.0 or newer versions, so that the writing and running speeds are faster. Next you need to download the ISO image file for Windows 10, and you can get the latest version from Microsoft's official website.

Then you need to use tools to write the ISO file to the USB flash drive. It is recommended to use Rufus or Microsoft's official Media Creation Tool . When operating, be careful to select the correct ISO file and target USB flash drive to avoid misformatting other devices.

• Make sure the USB drive has no important data (which will be formatted)
• Run the creation tool with administrator permissions
• Select the "GPT" partition type to adapt to the new computer (UEFI startup)

Set up the computer to boot from the USB drive

After plugging in the USB flash drive, restart the computer and enter the BIOS or UEFI settings interface. Different brands have slightly different ways of entering, generally pressing F2, F12, Del or Esc keys.

Find "Boot Order" in the boot options and set the USB drive to the first boot item. After saving the settings and restarting, if everything is working, you will see the Windows installation interface.

Note: Some notebooks need to turn off the "Fast Boot" function first, otherwise the USB drive may not be recognized.

Start installing Windows 10

After entering the installation interface, you will be prompted to select language, time and keyboard input method. After selecting, click "Next". Then click "Install Now", enter the product key (if you have), or select "I don't have a product key" to activate it later.

Next select the installation type:

• Upgrade mode (retain files and applications)
• Custom installation (clear the hard drive and reinstall)

In most cases, it is recommended to choose "custom installation", especially if you want to completely reinstall the system or replace it with a new hard drive.

Then select the installation location and remember to format or partition the hard disk in advance, otherwise errors will occur. Click "Next" to start copying the file. The whole process takes about 20 to 40 minutes, and it may automatically restart several times in the middle.

Some precautions after installation

After installing the system, don't rush to shut down. Check whether the drivers are complete, such as whether there are any abnormalities in basic functions such as graphics card, network card, and sound card. If there is no network driver, you may need to use wired connection or Bluetooth to share the network first.

In addition, Windows Update also recommends that you update it as soon as possible and add the latest security patches and feature optimizations.

• Installing the motherboard driver can improve hardware compatibility
• Check the system activation status (Settings > System > About)
• If it is a pre-installed genuine system, it will usually be automatically activated after the first time you connect to the network

Basically that's it. The whole process seems a bit too many, but each step is not complicated. The key is not to jump and do it step by step.
