Reinstalling the system is an inevitable problem for computer users, but for novice users, the difficulty lies in pressing the F key to enter the U disk to boot. PHP editor Xiaoxin has specially compiled a tutorial on reinstalling the system to help everyone get started easily. This tutorial will explain in detail the steps of reinstalling the system, focusing on solving the problem of pressing the F key to enter the USB disk to start, so that novice users can easily master the skills of reinstalling the system.

Tool materials:

System version: Windows 10 21H2

Brand model: Lenovo Xiaoxin Air 14

Software version: Xiaoyu one-click system reinstallation V5.0

1. Make a USB boot disk

1. First, you need to prepare a USB flash disk with at least 8G capacity, and then download one U disk boot disk creation tool. There are many high-quality boot disk creation tools on the market, such as Micro PE, Laomaotao, etc. Here I recommend using the Xiaoyu one-click system reinstallation tool. It is simple to operate and can create a boot disk with one click. It is very suitable for novice users.

2. After downloading and installing the Xiaoyu one-click reinstallation system, insert the U disk, select the U disk letter, click "One-click creation of boot disk", and wait for the creation to be completed. It is worth mentioning that Xiaoyu’s one-click system reinstallation also provides a system download function. You can download the required system image file directly in the tool.

2. Set BIOS startup items

1. After the startup disk is created, restart the computer and continuously press F2 (the shortcut keys may be different for different brands of computers) to enter the BIOS setting interface when booting. Use the direction keys to switch the startup item to U disk startup, and set U disk startup as the first startup item, save the settings and exit.

2. So here comes the question, how many times should I press F to boot from the USB flash drive? It really depends on your computer brand. Generally speaking, press F12 for Lenovo, HP, and Acer computers, press F8 for Dell and Asus computers, and press F11 for Gigabyte, MSI, and Sony computers. If you are not sure which F key to press on your computer, you can try a few more F keys when starting up. There will always be one that can enter the startup item selection.

3. Install the system

1. After setting up the U disk to start, the computer will enter the PE system. In the PE system, find the "System Installation" option, select the system version you want to install, and follow the prompts. If you are using Xiaoyu's one-click system reinstallation, the installation process will be simpler. You only need to click "One-click system reinstallation", enter the key, and it can be done in a few minutes.

2. After the system installation is completed, remember to install some necessary software on the computer, such as office software, anti-virus software, etc. In addition, it is also a good habit to regularly back up the system disk and important data to minimize the losses caused by reinstalling the system.

1. In addition to Xiaoyu’s one-click system reinstallation, Pocket Installer is also a very excellent system reinstallation tool. It has massive system image resources, supports one-click download and installation, and has built-in various practical auxiliary tools, such as driver installation, hardware detection, etc., which is very comprehensive and easy to use.

2. For some old computers, it may happen that the USB boot disk is successfully created but cannot be started. In this case, you can try to start the computer by "writing the hard disk master boot record". The operation method is to run DiskGenius in the PE system, select the system disk, and execute the "Rebuild MBR" function.

Summary: Reinstalling the system is a very practical skill. If you master it, you can solve many system fault problems by yourself without asking for help from others. Pressing the F key to boot into the USB flash drive is a key step in reinstalling the system. As long as you find the right shortcut keys, the subsequent installation process is very simple. If you are a novice user, you might as well try Xiaoyu's one-click system reinstallation. It is simple and easy to use, and one-click operation allows you to say goodbye to the trouble of reinstalling the system.
