Booting a Mac from a CD is a process that can be used to start up a Mac computer when it is unable to start up from its hard drive. There are a few different ways to do this, but the most common way is to create a bootable CD that contains an operating system installer. This article will discuss how to create and use a bootable CD to start up a Mac.
There are a few different ways to create a bootable CD that can be used to start up a Mac. One way is to use a program like Disk Utility to create an image of the installer and then burn that image to a CD. Another way is to use the createinstallmedia command in Terminal to create a bootable CD.
The most common way to use a bootable CD to start up a Mac is to create an installer CD. To do this, you will need to have the installer for the operating system that you want to install on your Mac. Once you have the installer, you can create a bootable CD by following these steps:
1. Open Disk Utility and select the “Burn” tab.
2. Select the “Image” button and select the installer file.
3. Select the “Destination” button and select your CD burner.
4. Click the “Burn” button to create the bootable CD.
Once the bootable CD is created, you can insert it into your Mac and start up your computer. The Mac will boot from the CD and start the installer. You can then follow the on-screen instructions to install the operating system on your Mac.

How do I select a boot device?
When your computer starts up, it needs to load an operating system so that you can use it. This process is referred to as booting. Your computer can boot from a variety of devices, including the hard drive, CD or DVD, or a USB drive.
The process of selecting a boot device is referred to as booting sequence or boot order. The boot order can be configured in the BIOS or UEFI settings.
You can access the BIOS or UEFI settings by pressing a specific key at startup. The key depends on the manufacturer of your computer. For example, on a Dell computer, you would press the F12 key at startup.
Once you have accessed the BIOS or UEFI settings, you can change the boot order. The order is typically listed in the order of the devices that will be booted. You can move devices up or down the list to change the order.
If you are not sure which device to select as the boot device, you can check the device’s manual or the manufacturer’s website.
Why computer is not booting from CD?
If a computer is not booting from a CD, there are several possible reasons why. One reason may be that the computer’s BIOS is not configured to allow booting from a CD. Another reason may be that there is a problem with the CD itself.
One possible solution to a computer that is not booting from a CD is to reconfigure the BIOS to allow booting from a CD. To do this, the user must access the BIOS configuration settings. The location of these settings may vary depending on the make and model of the computer. Generally, the BIOS settings can be accessed by pressing a specific key (such as F2, F10, or Delete) at the beginning of the boot process.
Once the BIOS settings are accessed, the user should look for a setting that allows booting from a CD. This setting may be called “Boot Order,” “Boot Device,” “First Boot Device,” or something similar. The user should set the CD drive to be the first boot device. Once this is done, the computer should be able to boot from a CD.
If the BIOS settings do not allow booting from a CD, or if there is a problem with the CD itself, there are a few other things that can be done. One solution is to try a different CD. Another solution is to create a bootable USB drive. For more information on creating a bootable USB drive, please see the following article:
