Troubleshooting: Boot from CD

Here we can see, “Troubleshooting: Boot from CD”

Many recovery guidelines recommend starting from a CD or DVD. The basics of troubleshooting the most common problems booting from a CD or DVD are covered in this knowledgebase article.

Troubleshooting Start the computer from a CD or DVD.

It could be any of several factors if you can’t get your PC to boot from a properly prepared bootable CD or DVD, even after following our guide on booting from CD or DVD.

Check to see if the CD is truly bootable.

It’s critical to make the bootable CD or DVD properly. Bootable discs are not the same as regular software that comes on a CD or DVD. The standard approach of copying or burning files onto a blank CD-R or DVD-R is insufficient to make a bootable CD. If you don’t have a physical copy of the bootable CD or DVD, you’ll need to convert an ISO file into a bootable CD or DVD by burning an ISO image of the data to the disc rather than the data itself.

Using free tools like ActiveISO and ImgBurn, you may make a bootable CD or DVD from an ISO image in our knowledgebase. You must carefully follow the instructions. You must not open the ISO file directly; instead, install the burning software you intend to use (ActiveISO or ImgBurn) and use that application to locate and open the ISO file you have downloaded.

Check if the computer is set to boot from the CD drive.

By default, most computers aren’t set up to try to boot from a CD or DVD drive. When your PC initially turns on, you must manually take action to force it to boot from the CD or DVD you’ve inserted. Refer to the instructions for setting up your computer to boot from a CD or DVD for more information.

Are you using Windows 8/10 or a PC with EFI/UEFI?

UEFI/EFI is a feature of newer Windows PCs and laptops that might make booting from recovery CDs and USBs difficult. Ensure your PC or laptop is configured to support booting from recovery CDs, DVDs, and USB sticks by following the instructions for enabling Legacy Boot and disabling Secure Boot.

Burning the CD at a slower speed is recommended.

Recreate the CD using the same validated instructions as previously, but burn it at the slowest speed possible (normally 1x or 2x). Bootable CDs are difficult to make because the BIOS is particular about the physical structure of the data tracks on the CDs, and any flaws in the blank CD/DVD media might result in errors in the final burned output. Burning at a slower pace ensures more consistent writes and frequently resolves issues caused by aged CD/DVDR media and burners.

The ISO picture should not be unzipped!

Do not extract or unzip the contents of what looks to be a WinZip or WinRAR file, a folder, or some other zipped archive! The file you downloaded is an ISO image, which may appear to be a ZIP file depending on how your computer is configured, but it is not. Follow the instructions for burning using ActiveISO or ImgBurn. Instead of double-clicking on the download file, open ActiveISO or ImgBurn and utilize the “browse” option to find and pick the ISO image you downloaded!

Don’t open the downloaded ISO image right away.

Follow the instructions for burning using ActiveISO or ImgBurn. Instead of double-clicking on the download file, open ActiveISO or ImgBurn and utilize the “browse” option to find and pick the ISO image you downloaded!

On a different computer, test the CD or DVD.

Try booting from the CD/DVD on another PC with an evident “boot selection menu” button to see if the problem is with your PC’s configuration or the CD/DVD you’re trying to boot from.

Another CD or DVD should be used to test the PC.

Try starting your PC from any other guaranteed-bootable CDs you have laying around, such as the original Windows setup CD/DVD or your PC’s restore discs. This will determine whether the issue is with your PC or your CD/DVD.

User Questions

1. Why won’t my PC boot from a CD?

The computer may disregard or not look at the CD-ROM or DVD as a bootable option if the BIOS is not properly set up. Open BIOS setup and double-check that your boot sequence is set to boot from the CD-ROM device. These options can be found in the boot options menu.

2. How can I force a DVD to boot?

Insert the DVD while Windows is still operating and reboot. During boot time, pay attention to the on-screen wording and hit the appropriate key when you read ‘Select Boot Device,’ ‘Change Boot Order,’ or another similar command. Esc, F10, or F12 are likely to be the keys.

3. How can I tell if my CD can be booted?

If you want to check a physical media disc, you can also attempt Open CD/DVD Driver and then CD-ROM/DVD-ROM drive letter. MagicISO will display Bootable on the menu bar if the media or image file is bootable, and the ISO image will be bootable when burned to CD, DVD, or USB flash drive.
