I believe that after using the computer for a period of time, you will want to change to a new one. So how to restore the computer to the factory settings before resale? Next, the editor of Superman Software would like to introduce to you how to reinstall the computer system, hoping to help you.
How to restore computer to factory settings?
1. Shut down the computer and then turn it on or directly click to restart, then press and hold the "DELETE" key, at this time, the computer will automatically enter the BIOS;
2. Two options will be displayed on the computer screen (the two options are generally on the right side of the computer screen), as shown in the first picture;
3. One of the options is the "Load Fail-Safe Defaults" option (system preset stability parameters). There is also an option "Load Optimized Defaults" (the best parameters preset by the system);
4. At this time, select the "Load Optimized Defaults" option, and then use the arrow keys to select it directly. After pressing Enter to confirm, the system will prompt a prompt, then click the Y key, and then press Enter to confirm. Finally, save the previous settings, just click "Save&exit step" or press F10.
However, please pay attention to restoring the factory settings and restoring to the original state. The files on the desktop and the files on the C drive will also be deleted. If you have important files, please backup them to other disk partitions first to avoid file loss!
How to reinstall the computer system?
1. CD installation method:
Brief description: The CD-ROM installation method can be regarded as the most classic, the most compatible, and the easiest to learn installation method. It can be upgraded and installed, or can be installed completely (you can choose to format the old system partition during installation), and the installation method is flexible. Not limited by the old system, 32/64-bit system can be installed flexibly.
method:
1. Download the ISO file of the relevant system installation disk and burn it for backup. (If you have a CD, you can omit this step)
2. Boot into BIOS (generally press DEL or F2 or F1 key to enter during hardware self-test, different computer settings are different), and set the CD-ROM drive to start first. Press F10 to save and exit.
3. Insert the CD, restart the computer, and the CD will boot into the installation interface. Install according to the appropriate options. When choosing the partition location of the installation hard disk, you can choose a blank partition or an existing partition, and you can format the partition. Others are no longer detailed.
Disadvantages: In the case of the WIN7 test version flying all over the sky, this disk installation is undoubtedly the most extravagant, most wasteful, and the least environmentally friendly method. It is only recommended if other installation methods are not available or competent.
