Turning on the computer from disk is usually required to recover the operating system from a major failure. To properly turn on the computer from the CD, you need to follow a specific sequence of steps.
Instructions
Step 1
In order to boot a computer from a CD, you need to have a special version of the operating system. designed to run from CD. These assemblies are called LiveCDs and are typically built from open source operating systems. However, there are versions of Windows operating systems made for the LiveCD format. One of them can be downloaded from the link https://philka.ru/forum/index.php?showtopic=6879. After downloading, write this assembly to a CD-RW disk for use in emergency situations, for example, in case of a virus infection of the computer or a critical failure of the operating system settings
Step 2
In order for the computer to boot from a CD, it is necessary to set its settings in such a way that the priority on the media from which the operating system is loaded is set to CD. To do this, you need to enter the computer BIOS by pressing the F1, F2 or F9 buttons (depending on the manufacturer) immediately after turning on the power. In the BIOS, go to the Boot Options tab and edit the boot queue by placing the CD first in the queue. After that, insert the CD into the drive and restart your computer using the keyboard shortcut Ctrl + Alt + Del. After the reboot is complete, wait until the screen displays "Press any key to boot from CD". Now press any key to start boot from disk.
Step 3
Loading the operating system from the disk will take a little longer than the standard one. After loading, the desktop with shortcuts of the programs included in the assembly will appear on the screen. As a rule, the assembly includes file managers, registry editors and antiviruses that will help solve most of the problems encountered with the standard operating system.
