Here are a few of the remedies you could need to get your computer to boot up and into its next system phase based on the solutions you’ve already tried.

Method 1: Remove Unnecessary Hardware Components

There is a lot of unnecessary hardware on the ordinary computer. Some common issues can be solved by removing this device. For example, if Windows is unable to begin the process of booting the computer, it may be due to an obstruction.

Removing unused components might help free up space and restore functionality to your computer. The issue may be caused by a BIOS bug, according to certain theories. When a computer has a large number of peripherals attached, this error is likely to be a result of this.

From this vantage point, remove any non-critical hardware, such as USB devices, network adapters, sound cards, and serial cards. During the installation procedure, detach any hard drives or SSDs that are not required.

Remove any active optical drives from your PC as well. Installing a new operating system on a PC with minimal hardware requires a restart. Error messages are unlikely to reappear during the installation process.

Method 2: Prepare the Installation Media Properly

Another factor that could contribute to an increase in the number of reports of this problem is a media installation that was poorly written. Fix Windows that couldn’t boot correctly by properly preparing the installation media.

In other words, make certain the installation media is free of faults and clean. When utilising a USB drive, ensure that you are using a USB 2.0 port. Clean and undamaged DVDs should be used whenever possible.

To fix the “Windows could not prepare the computer to boot” issue, follow these steps:

  1. To begin the process of installing Windows on a PC, first download the Rufus tool.
  2. Upon installation, pick the disc image file for your preferred device and begin the programme.
  3. To make your USB ready for the Windows file installation, simply click the Start button once you have picked your Windows file.
  4. To see if the “Windows could not prepare the computer to boot” error on your computer has been resolved, you must install this Windows file on your computer after your USB has been made bootable.

Method  3: Check to Make Sure Your BIOS Is Compatible With Your Windows Version

Your BIOS may need to be updated if your machine isn’t booting properly. However, you should check to see if your BIOS supports the Windows version you’re trying to fix. Please note that if it doesn’t, you won’t be able to follow the directions on this page to fix the problem.

Visit the manufacturer’s website and seek for a downloads or help section to see if the BIOS supports the Windows version you’re trying to fix. Look for a BIOS update for your specific model of computer once you’ve located it. Double-clicking the file will begin the installation procedure.

If you choose to upgrade your BIOS, you’ll be prompted to do so throughout the installation process. Make a copy of your current BIOS just in case something goes wrong with it. As an alternative, if you see the error message “This system cannot boot,” you might try to install a new version of Windows on your computer.

Method 4: All Computer Partitions Can Be Deleted

Some of the affected users have reported that they were able to complete the installation without encountering the “Windows could not prepare the computer to boot into the next stage of installation” error only after deleting all partitions and starting the OS installation from the ground up.

One or more of the partitions on your computer may not be correctly formatted if it won’t boot. This can be remedied by erasing all of your computer’s partitions, although doing so does not guarantee that the computer will boot.

Most of the time, a simple hard disc reformat and reinstall of Windows is all that is needed to fix the problem. If you’ve only been interested in updating an existing Windows installation, this can be a huge problem.

If you’ve tried everything up to this point and are still having no luck, you may want to try something else. Cloning your system image first will create a Windows repair disc so you can go back to the beginning of the process if anything goes wrong.

You’ll need to follow these steps to carry out this method:

  • When you make a right-click on the Windows icon, select “Device Management” from the list that appears.
  • You’ll see the computer’s hard drive partitions in front of you now. All but the first “C” partition should be deleted. Make sure you back up your important files before deleting them from your computer.

To free up space on the drive, you must first delete the partition and all of its data, then extend another partition or format the disc in a new format.
