Your computer needs to copy thousands of tiny files from your USB drive to your main hard drive to install Windows. If the disk fails to read or write even one of these files, it stops the entire process to prevent a broken operating system.
Most users see this error at a very specific moment. The Windows setup screen will show a progress bar for a step called getting files ready for installation. The percentage will usually climb to a certain number and then freeze completely. A blue box will pop up stating that Windows cannot install required files, followed by the 0x8007025d error code.
If it fails to read even one file, it throws the Windows cannot install required files error for three main reasons:
Corrupted USB Drive: The installation files for Windows 10 or Windows 11 on your flash drive are broken, or the download was interrupted.
Failing RAM: The memory sticks inside your computer are physically damaged and dropping data during the transfer.
Bad Hard Drive Sectors: The main hard drive you want to use has corrupted partitions and refuses to accept the new files.
You can fix this installation error by testing your hardware and resetting your drives. We will start with the easiest hardware tricks and move to software repairs.
Extra devices plugged into your computer can confuse the motherboard during a heavy file transfer. Unplugging them forces the computer to focus only on the installation drive.
Step 1: Turn your computer off completely.
Step 2: Unplug all external hard drives, extra flash drives, printers, and webcams.
Step 3: Leave only your mouse, keyboard, and the Windows installation USB plugged in.
Step 4: Turn on the computer and try running the Windows setup again.
A bad internet connection can corrupt the Windows download, or the USB flash drive itself might have bad sectors. Creating a new installation drive on a different USB stick is the most reliable fix.
You will need a working computer and a brand new USB flash drive with at least 8GB of space.
Step 1: Plug the new USB drive into a working computer.
Step 2: Go to the official Microsoft website and download the Windows Media Creation Tool.
Step 3: Open the tool and select the option to create installation media for another PC.
Step 4: Choose your language and Windows version. Select the USB flash drive option.
Step 5: Let the tool download a fresh copy of Windows and format the USB drive. Plug this new drive into your broken computer and try the installation again.

1. Does this error mean my hard drive is completely dead?
Usually, no. It is much more likely that your USB flash drive is corrupted or the Windows download was interrupted by a bad internet connection. You should always try making a brand new installation USB before you spend money on a new hard drive.
2. Why does the Windows setup freeze at the exact same percentage every time?
When the setup freezes at a specific number like 15 percent, the computer is hitting a specific broken file on the USB drive or a specific bad sector on the hard drive. It cannot read past that broken spot, so it stops the installation and throws the error code.
3. Can I install Windows without using a USB drive?
If your computer already has a working version of Windows on it, you can download the Windows Update Assistant from the Microsoft website. This tool lets you upgrade your operating system directly from your desktop without needing a USB drive. If your computer is completely blank or broken, you must use a USB drive to install Windows.
