There are two commonly used methods: hard disk upgrade and U disk installation upgrade. The hard disk upgrade is to download the system, decompress it to the root directory of the non-installation disk for installation. But people more often use the method of U disk installation.
1. First, you need to prepare an empty 4G or above U disk to store the startup program and system files.
2. Then we need to install the system house GHOST system.
3. U disk boot disk creation tool: u boot
U disk boot disk production steps:
1. Everyone downloads "uboot" and installs it.
2. Open u boot, insert the prepared u disk into the computer usb interface, and wait for the software to automatically recognize the inserted u disk. Then, without modifying any options in the interface, click "Start Production" to:
3. At this time, a pop-up warning will appear: "This operation will delete all data and cannot be restored." If there are important data in the U disk, you can back up the data to the local disk and confirm that the backup is complete or there is no important data. Then we click "OK" to execute the production,
4. It takes about 5-10 minutes to make a U disk boot disk. During this period, please wait patiently and do not perform other operations to ensure the smooth completion of the making process:
5. After the U disk boot disk is made, a new prompt window will pop up. For this, we click "Yes" to perform a simulated boot test on the created U disk boot disk to test whether the U disk boot disk is available.
6. If you see the following interface in the simulation startup, it means that our U disk startup disk has been made successfully (note: the simulation startup interface is only for testing, please do not operate further), and finally press the key combination "Ctrl+Alt" to release Mouse, click the close icon in the upper right corner to exit the simulation startup interface:
U disk installation system steps:
1. After the U disk boot disk and files are copied into the U disk, insert the U disk into the computer and restart.
2. Set the U disk as the first startup item. For related tutorials, see this: BIOS setup hard disk startup installation method.
3. Store the prepared Win7 system image package in the root directory of the U disk boot disk that has been prepared:
4. First connect the OSU USB boot disk to the computer, restart the computer and wait for the boot screen to appear, press the startup shortcut key, use the U disk boot disk to enter the OSU main menu, and select [01] Run OS Home Win8pe X64 Official version, press Enter to enter,
5. After entering pe, it will automatically start the system home pe installation tool. First, click "Browse" to add the system image saved in the U disk, then select the c disk as the system disk to store the image, and click "OK".
6. After the disk is formatted, the Win7 image file will be installed.
7. At this point, you can remove the u disk, restart the system to start the installation, we do not need to do any operations, just wait for the installation to complete, and it will restart once before entering the system desktop, as shown in the following figure:
8. After the computer restarts, it will automatically mirror the Win10 upgrade work. You don't need to do anything during the restart, just wait patiently.
