📋 Table of Contents
The 'FATAL: Could not read from the boot medium. System halted' error occurs when VirtualBox is unable to load the Windows 7 installation media during the boot process, affecting users who attempt to install or run Windows 7 within a VirtualBox environment.
This issue can be frustrating for users trying to create and manage virtual machines, as it prevents them from accessing their desired operating system. In this guide, we will walk through the steps to troubleshoot and resolve this error.
🛑 Root Causes of the Error
- The primary reason for this error is that VirtualBox is not able to read the Windows 7 .iso file correctly due to issues with the ISO file format or corruption within the file. This can be caused by various factors, including incorrect burning of the iso file during creation, incomplete download of the iso file, or damage to the iso file during transfer.
- An alternative reason for this error is that the Windows 7 .iso file is not compatible with VirtualBox's ISO file format, which may be due to the version of the iso file being used (e.g., Windows 7 Ultimate vs. Windows 7 Home).
🛠️ Step-by-Step Verified Fixes
Checking and verifying the ISO file
- Step 1: Ensure that the .iso file was burned correctly using a reputable burning software, such as Nero or ImgBurn. If you used a free burning software, try re-burning the iso file to ensure its integrity.
- Step 2: Verify that the .iso file is not corrupted by checking its size and contents for any errors. You can use tools like CheckDisc or ISO Editor to inspect the .iso file's contents.
- Step 3: Try using a different .iso file of Windows 7, either from the same source as the original or from a trusted online repository.
Configuring VirtualBox settings
- Step 1: Ensure that the virtual machine's boot order is set to prioritize the CD/DVD drive. To do this, go to the 'Settings' > 'Storage' and adjust the 'Boot Order' to place the CD/DVD drive first.
- Step 2: Verify that the IDE controller is enabled for the CD/DVD drive. To do this, go to the 'Settings' > 'Storage' and ensure that the 'Controller IDE' is enabled.
🎯 Final Words
To resolve the 'FATAL: Could not read from the boot medium. System halted' error in VirtualBox while installing Windows 7, try checking and verifying the ISO file for corruption or compatibility issues, and configure VirtualBox settings to prioritize the CD/DVD drive.
