Windows 10 has many advantages, but it is one of the most difficult systems to update because of the many errors that users encounter during installation. One of them is the error 0x8007025D that appears and interrupts the installation after a certain percentage. Retry will only give you the same error. Several people who looked for answers online said they were performing a new installation from their USB key.
This page will explain why error 0x8007025D appears. There are several issues that may be causing the error, but they are all related to the USB buffering system. After a brief explanation of the meaning of the error, we will tell you the steps to follow to resolve it.
If you want to solve the problem, you must follow the solutions mentioned below. It is not necessary that with the first method, only your problem is solved. So, continue with all the solutions until your problem is solved.
Here you will learn how to fix the error 0x8007025D of Windows 10 and not how to install Windows 10.
Solution 1: Unplug All other External Devices
Remove all your USB devices and other devices, including the Internet cable. Most of the time, installing Windows generates an error simply because of faulty hardware or outdated drivers.
Sometimes, just after copying the files to your computer, the installation of Windows no longer needs a USB key. Just remove the drive and check if the installation process continues where it left off.
Go to the next method even if it does not work after a new attempt.
Solution 2: Reduce the Size of HDD or SSD Disk Space and Format it
To install Windows 10, you need about 20 GB of space. If you reduce your installation partition to approximately 125 GB, it is unlikely that the space you are copying will be corrupted. The disk space can be expanded by clicking on the EXTEND option after choosing the custom installation of Windows 10. Your hard disk must be in good condition or not be damaged in any way.
If you are performing a new installation, be sure to format the partition in which you are installing. This will remove all sectors and bad records. To format a partition, choose to install custom Windows 10. Click the Format button and accept the formatting.
Solution 3: Download a New Windows 10 ISO Image File
It is possible that the image file you downloaded is a corrupted file. And these files would not be decoded or copied. It is certainly possible that the file is missing on the USB key that you downloaded via the image creation.
You will need to download the files again, create a USB installation and restart the installation process. For the .ISO file for Windows 10 download, go to the Microsoft page. You will get instructions on how to download the file and use the Media Creation Tool to create a bootable USB drive.
Solution 4: Write the Image on another USB Drive
If the USB drive is corrupted or has an unreadable section, the buffer technology will detect it and generate an error 0x8007025D. In addition, you will need a new USB drive to follow this method. Create the installation files in the new drive and restart the installation process. Creating the installation drive from another computer resolves the problem. If you are using USB 3.0 previously, use USB 2.0 instead because it uses a different technology to read the data.
Solution 5: Run a Memory Diagnostic on Your RAM and Replace a Bad RAM
If all the above solutions fail, there could be a problem with your PC. The Windows 10 configuration would prefer not to install Windows on your device if it finds faulty RAM memory rather than crashing after installations.
If you have 2 RAM keys (at least 1 GB), try disconnecting and trying the installation. Exchange if the first one returns an error. You can also search for RAM errors by using the Memory Diagnostic Tool in the BIOS. Follow the steps below to run a memory diagnostic successfully.
- Boost your PC immediately. Press the f2, f8, or f10 keys (depending on your computer) repeatedly to access the BIOS Setup window.
- Use the LEFT and RIGHT ARROW keys to select diagnostics.
- Use the DOWN and UP keys to select the memory test. Press the ENTER key to begin the test and record the errors.
- If the problem persists or if you notice an error in your RAM, replace it and start the installation process again.
