First, make a USB flash drive into a PE to start the USB flash drive. This will not be detailed. On the internet, just start the USB flash drive with the "depth" or "cabbage" tool and make it into a PE to start the USB flash drive.

Boot, enter the BIOS of Lenovo brand machine, and change the hard disk mode to compatible with the Legacy mode. After entering the PE, use the partition software diskgenius for partitioning. The mode is MBR, And you can divide it into several zones.

Next, create an original win7 image to start the USB flash drive. Use the USB flash drive UltraISO under PE to open the WIN7 image. Choose start-write hard disk image from the menu, select the USB flash drive, and click "write ", after several minutes, the system prompts that the write is successful. According to the general situation, the preparation of the original WIN7 image is complete, but Lenovo's new computer generally only supports USB3.0. If the image is not injected with the USB3.0 driver, during the installation of the original image, the following message is displayed: "The CD/DVD drive cannot be found after WIN7 is installed." The reason is that there is no 3.0 driver. During the installation of WIN7, the USB flash drive of the boot disk of the original image cannot be found, so that the next operation cannot proceed.

Therefore, we need to inject the USB driver into the original image USB flash drive. Win7-USB3.0-Creator software official website has support WIN7 and WIN8-10 two, choose WIN7 download. Open the software, the operation interface is very simple, select the original WIN7 image to start the U disk, click "CREATE", around 15-20 minutes later, WIN7 USB 3.0 injection successful, the complete original WIN7 image is used to start the USB flash drive.

The next step is to install the original version of Windows 7. Insert the original image of Windows 7 and start the USB flash drive. Then, enter BIOS settings, select Devices-USB setup, and change "USB Virtual kbc support to Enabled. You can test the settings during installation. If you do not set the settings, after the installation is complete and enters the WIN7 system, you will find that the USB mouse and keyboard remain unchanged, in fact, the previous USB injection was actually designed to provide support for USB during the installation process, followed by the Lenovo-branded computer USB driver after the WIN7 system. You can test it in the actual process. If USB3.0 is not injected or the BIOS is not set, problems may occur.

To avoid detours, set the BIOS and restart the system. Press F12 to start the USB flash drive. The next step is simple. Follow the prompts to proceed step by step to enter the WIN7 interface.

After the WIN7 system is installed successfully, install the USB driver and NIC Driver of the Lenovo computer downloaded earlier, connect the network cable, and use the Lenovo driver to manage the driver or install the driver one by one, in this way, we are done. If the Organization has many Lenovo computers of the same batch Model, use GHO to back up one computer and restore one computer one by one.
