If your computer won’t boot up from a CD/disk, there are a few potential solutions you can try to improve your chances of success. Before attempting any of the solutions outlined below, it is important to first ensure the CD/disk is not defective by examining it for any physical damage or defects.
Solution 1: Check BIOS Settings
The first thing to check on a computer that won’t boot from a CD/disk is the system’s BIOS settings. These settings determine how the computer will recognize and start up from different types of bootable media. To access the BIOS settings, restart the computer and press the key combination indicated by the BIOS manufacturer during startup.
Once inside the BIOS menu, look for an option labeled “Boot Device Priority” or “Boot Order.” Depending on your system, this option may appear differently. Within this menu, check to make sure the CD/disc drive is set as the first boot device. If it is not, change it to the top position.
Some systems have a “Safe Boot” option which must also be disabled. Once you have finished configuring the BIOS settings, save and exit.
Solution 2: Change Boot Mode
Depending on the manufacturer and model of your computer, it may be necessary to change the boot mode from legacy to UEFI in order for the system to recognize the CD/disk. To change the boot mode, enter the BIOS settings and look for a “Boot Mode” option. On some systems, the option may be labeled “Legacy Boot Mode” or “UEFI Boot Mode.”
When changing the boot mode, make sure to save the changes and exit the BIOS after making your selection.
Solution 3: Check System Drivers
If the CD/disk still isn’t being recognized by the computer, check the system drivers. Outdated or malfunctioning drivers can interfere with the system’s ability to detect the CD/disk. To update the drivers, enter the BIOS menu, select “System Devices,” then choose “CD/DVD-ROM Driver.” Update the driver and save the changes before exiting.
Solution 4: Check Data Connectors
If the CD/disk is still not being recognized, you may need to check the data connectors on your system. Outdated or faulty data connectors can cause the system to fail to detect the CD/disk. To check the data connectors, remove the CD/disk drive from the system, then examine each connector for signs of wear or damage. If necessary, replace the data connectors with new ones.
Solution 5: Clean the Disc
Sometimes, the CD/disk may not be recognized due to dirt, dust, or other substances that have collected on its surface over time. To clean the disc, use a soft cloth and wipe it gently in a circular motion. Make sure to avoid touching the CD/disk’s recording surface as much as possible. Once you’ve finished wiping the CD/disk, insert it back into the system and check if it is now being recognized.
Solution 6: Replace the CD/Disk Drive
If the above solutions do not work, the last resort is to replace the CD/disk drive. Over time, CD/disk drives can become outdated or malfunction, so replacing it may be necessary in order to get the system working properly again. Replacing a CD/disk drive involves removing the old one from the system and installing a new one. The process can be complicated, so unless you are experienced with hardware installation, it is recommended to take your system to a professional for assistance.
In conclusion, if your computer won’t boot from a CD/disk, there are several solutions you can try to get it working again. Start by checking BIOS settings, changing the boot mode, and updating system drivers. If these solutions don’t work, you may need to check the data connectors or clean the disc before replacing the CD/disk drive.
