Easy Windows installation process
A clean installation is a manual startup of the system disk during computer startup. After that, start, press any button, after the message “Press any key” appears on the tap.
The BIOS indicates the location of the new OS, for example, on a CD / DVD or on a hard disk, so that the old version is not used at all, or has been deleted. The clean version is used for any OS: Unix, DOS, Windows XP, as well as Linux, Windows 8 and Windows 7.
Simple is rarely used and is not recommended. This is due to the fact that the new version is launched from a CD / DVD disc already installed by the old OS. So a simple installation is more like the “overlay” process, since the new version is overlaid on the old version.
Difference in installation processes
Easy installation of Windows:
- Computer startup;
- Operating system;
- Computer startup;
- Clean install.
Operating system hard disk partitions.
Often during a clean install, all partitions are formatted and old versions and files are removed. If you need to reinstall a system with several partitioned disks where important files are stored, you can leave the information unchanged.
It is not necessary to format the D drive, however, the C drive containing the old Windows files will be formatted.
Analysis of the hard disk during installation.
Before starting the installation of Windows (with a non-working OS, crashes and glitches), you need to try to use the last chance to restore and clean from malware.
In case of clearly expressed problems with the operation of the PC, it is necessary, first of all, to check the state of the hard disk, analyze the work of the segments, otherwise, even during the installation of the system, the formatting process may freeze or work unstably.

Personal data and information is a very important component that cannot always be restored in case of deletion or damage, therefore, before reinstalling anything, you need to take care of their safety.
To save information and personal data when reinstalling Windows, you need to copy and transfer all the necessary files to a portable medium (disk, USB flash drive, etc.). It is also very important to save passwords, for this it is recommended to use the Backup program or do it the old-fashioned way, manually.
By exactly following the rules and tips, you can understand how to install Windows via BIOS on a computer, even for a person without special skills and experience, in such situations.
