There are a few potential reasons why the Ubuntu live CD installer may fail to start. Here are a few things you can try to troubleshoot the issue:
- Check the integrity of the installation media. If the installation media (e.g., the live CD or USB stick) is damaged or corrupted, it may cause the installer to fail to start. You can check the integrity of the installation media by running the checksum on it and comparing it to the official checksum provided by Ubuntu.
- Check the boot order in the BIOS/UEFI. The live CD installer may not start if the boot order is not set correctly in the BIOS or UEFI (Unified Extensible Firmware Interface). To check the boot order, you will need to restart your computer and enter the BIOS or UEFI settings. Look for a menu option that allows you to specify the boot order, and make sure that the device with the live CD or USB stick is listed first.
- Check for hardware issues. If there are hardware issues with your computer (e.g., a damaged hard drive, faulty RAM, etc.), it may prevent the live CD installer from starting. You can try running a hardware diagnostic tool to check for hardware issues.
- Check for software issues. If you have installed other operating systems or software on your computer, it may cause conflicts with the live CD installer. You can try booting into Safe Mode or a “clean boot” state to see if this resolves the issue.
To start the Ubuntu live CD installer, you will need to boot your computer from the live CD or USB stick. Here’s how you can do this:
- Insert the live CD or USB stick into your computer.
- Restart your computer.
- Press the appropriate key to enter the BIOS or UEFI settings. The key you need to press will depend on your computer’s manufacturer. Common keys include F2, F10, and Del.
- Once in the BIOS or UEFI settings, look for a menu option that allows you to specify the boot order. Make sure that the device with the live CD or USB stick is listed first in the boot order.
- Save your changes and exit the BIOS or UEFI settings.
- The computer should now boot from the live CD or USB stick and start the Ubuntu live CD installer.
