Method 4: Download the ISO from Microsoft
Anyway, if Windows Update fails to install on your system, you can try repairing the files or installing a new Windows. To do so, visit the official Microsoft website and download the ISO file. After downloading, you will need a USB drive or a disc along with the Media Creation Tool. To avoid any mishaps, we recommend using the Partition Master Professional tool, which aids users with its smooth process.
This tool provides the easiest way to create a bootable disk on a USB drive or CD. Moreover, it helps resolve Windows boot issues such as system crashes, screen freezes, and blue screen errors. The steps to create a bootable disk using the Partition Master tool are as follows:
Step 1. To create a bootable tool disk, you need a storage medium such as a USB drive, a flash drive, or a CD/DVD disc. Connect the drive to your computer properly.
Step 3: If you have a USB or CD/DVD drive, you can choose it. If not, you can also save the ISO file to your local disk and burn it to a media device later. After making your selection, click "Create" to start the process.
- Review the warning, and then click Yes.
Step 4: When it's done, you'll see a pop-up asking if you want to restart your computer from the bootable USB drive.
- Restart Now: means that you want to restart your computer now and boot from the installation media to manage disk partitions without an operating system.
- Finish: means that you do not want to restart your computer now, but instead want to use the live USB on a different computer.
Note: To boot from the USB drive on a new computer, you will need to restart the target computer and press F2/F8/DEL to enter BIOS, then set the USB bootable drive as the first boot device.
Wait patiently, and your computer will boot from the USB drive and load the WinPE tool desktop automatically.
Method 5: Free up disk space

Now it's time to learn how to use this tool to clean up your disk.
