Newly bought Shenzhou notebook. The system is a new Kirin. I want to change it to win7' to find out the detailed steps.

1, look at the computer configuration, mainly memory. If the memory is larger than 4GB, it is recommended to install Windows 7 64-bit, which can make full use of the memory of the notebook computer. If the memory is less than 4GB, it is recommended to install Windows 7 32-bit.

2. Find a Windows 7 installation CD through a friend or go to a software store to install it through a CD-ROM drive (you can also install it through a USB flash drive and downloaded ISO files, but the steps are much more complicated than the CD-ROM drive installation, so don't say it). And through other computers, download and install the drivers needed by the system.

3. Put the CD into the CD-ROM drive, then turn it on, press F 12 to enter the system boot device, and select DVD drive to start (you will see the word DVD, just select it! )。

4. After successfully booting from the CD, the system installation interface will be loaded, and the installation partition will be selected according to the installation prompts. At this point, all partitions of the hard disk will be deleted, and then the partitions will be repartitioned and formatted. The setting size of drive C is 60~80GB, and the size of other partitions depends on your preference. More than 80GB is recommended to avoid too many partitions.

Note: If you can't see the hard disk when installing the selected partition after booting from the CD, you need to restart, press F2 to enter the BIOS, and change the hard disk mode in the BIOS to IDE or compatible mode (as long as it is not ACHI mode).

5. After installing the system, copy the previously downloaded driver to the computer, and then install the driver. It is recommended to install drivers in the order of motherboard, graphics card, sound card and network card.

Good luck!
