parallels desktop install ubuntu 18 cd-rom not found

Installing Ubuntu 18.04 using Parallels Desktop can sometimes encounter unexpected snags. One common issue is the dreaded "CD-ROM not found" error during the installation process. This seemingly simple problem can stem from several underlying causes, making troubleshooting crucial. This guide will walk you through the most effective solutions to overcome this hurdle and successfully install Ubuntu 18.04 on your Parallels Desktop virtual machine (VM).

Understanding the "CD-ROM Not Found" Error

Before diving into solutions, let's clarify what this error signifies. When Parallels Desktop reports a "CD-ROM not found" during Ubuntu 18.04 installation, it typically means the virtual machine isn't properly recognizing the installation media. This isn't necessarily a problem with your physical CD/DVD drive; instead, it's a configuration issue within the Parallels environment.

Troubleshooting Steps: Resolving the "CD-ROM Not Found" Error

Here's a step-by-step approach to resolve the "CD-ROM Not Found" error:

1. Verify Installation Media

Check the ISO File: Ensure you've downloaded a valid and correctly functioning Ubuntu 18.04 ISO image. A corrupted download is a common culprit. Try re-downloading the ISO from the official Ubuntu website to rule this out.
ISO File Path: Double-check that you've selected the correct path to your ISO file within Parallels Desktop's VM settings. An incorrect path will prevent the VM from accessing the installation media.

2. Parallels Desktop Settings: Configuring the Virtual CD/DVD Drive

This is often the core problem. Here's how to configure it:

Access VM Settings: Open Parallels Desktop, select your Ubuntu VM, and go to its "Configure" settings.
Hardware Tab: Navigate to the "Hardware" tab within the settings.
CD/DVD Drive: Locate the "CD/DVD Drive" section. Make sure a virtual drive is assigned.
Select the ISO: Click the "Choose..." button and browse to the correctly downloaded Ubuntu 18.04 ISO file. Select the file and click "OK".
Connection Type: Ensure the connection type is set to "Use ISO image file". This is essential for using an ISO file instead of a physical CD/DVD.
Restart the VM: Restart your virtual machine after making these changes. This ensures the changes are applied.

3. Checking for Conflicting Hardware or Software

Other Virtual Machines: If you're running other virtual machines concurrently, there might be resource conflicts. Close other VMs to ensure sufficient resources are dedicated to your Ubuntu 18.04 installation.
Parallels Tools: Sometimes, outdated or improperly installed Parallels Tools can interfere. Try uninstalling and reinstalling Parallels Tools within the Ubuntu VM after the initial boot. (You may need to perform this step after the OS is partially installed).
Antivirus/Firewall: Temporarily disable your antivirus and firewall software. They sometimes interfere with virtual machine operations. Remember to re-enable them once the installation is complete.

4. Create a New Virtual Machine

Fresh Install: As a last resort, consider creating a completely new virtual machine. This eliminates any lingering configuration problems from previous attempts. Ensure you follow the correct steps for selecting your Ubuntu 18.04 ISO when setting up the new VM.

Preventing Future Issues

Keep Parallels Desktop Updated: Regularly update Parallels Desktop to benefit from bug fixes and performance enhancements. Outdated software can introduce compatibility problems.
Use Official ISOs: Always download Ubuntu ISOs from the official Ubuntu website to avoid corrupted or tampered-with files.

Successfully installing Ubuntu 18.04 within Parallels Desktop should be a smooth process. By methodically following these troubleshooting steps, you can overcome the frustrating "CD-ROM not found" error and enjoy your new Linux environment. Remember to always back up important data before making significant system changes.
