Jul 04, 2025 am 12:47 AMError code 0x8007025D is usually caused by the installation program being unable to read and write the disk. 1. Check the USB disk connection and use Microsoft official tools to remake the installation disk; 2. Clean the partition table through the command prompt and rebuild the GPT format; 3. Run chkdsk to check the bad channel; 4. Switch the disk mode to AHCI in the BIOS and update or disable the RAID driver; 5. Replace the USB disk or verify the integrity of the ISO image; 6. Try different versions of Windows ISO; 7. If it is still invalid, it may be that the hard disk is faulty and needs to be replaced.
Error code 0x8007025D appears during Windows installation, which usually means that the installer cannot read or write to the target disk. This problem may be caused by a variety of reasons, including hardware problems, driver incompatibility, incorrect partition format, or problems with the installation media itself. When encountering this error, don’t rush to try again first, but check it in a targeted manner.

Check whether the USB or hard drive connection is normal
In many cases, this error is caused by poor contact with the installation media (usually the USB flash drive) or unstable read and write. You can try the following steps:

- Try changing the USB drive to another USB port, and use USB 2.0 instead of 3.0 first.
- If you are using an external hard disk box, change the box and test it
- Make sure that the corresponding USB port is enabled in the motherboard BIOS (some motherboards turn off some interfaces by default)
In addition, if you are creating a USB drive boot disk on a computer with an existing system, it is recommended to re-create the USB drive. It is best to use Microsoft's official tools such as Media Creation Tool to ensure that the files are intact and lossless.
Format the target disk and check for bad channels
If the USB drive is fine, it may be that there is a problem with the target disk. In the installation interface, select Repair Computer > Troubleshoot > Command Prompt and enter the following command to clean and rebuild the partition table:

diskpart list disk select disk X (X is your hard disk number) Clean convert gpt (if your motherboard supports UEFI)
Then exit the command prompt and try to install again. If it still doesn't work, you can run chkdsk /f /r
to check for bad channels or file system errors.
Update or disable RAID/Storage Controller Driver
RAID or NVMe drivers on some motherboards may cause the installer to not recognize the disk. You can try:
- Enter BIOS to switch disk mode from RAID to AHCI (Note: This may cause the installed system to fail to boot)
- In the installation interface, press Shift F10 to open the command line, enter
devmgmt.msc
to see if there is an exclamation mark device, and confirm whether additional drivers need to be loaded - Use the latest version of Windows ISO image, which contains more new models of support drivers
If you really can't find a suitable driver, you can also try to temporarily disable the RAID function and adjust it after the system is installed.
Replace the installation media or try another ISO version
Sometimes the problem lies in the installation USB disk itself or the ISO image is damaged. You can try:
- Use another computer to re-download the ISO file and use the verification tool to check the SHA256 value
- Change a USB drive or SD card to create an installation disk
- Try using different versions of ISO on Windows 11/10 (such as changing from home to professional)
If you have tried all the above methods but it doesn't work, it may be a hardware-level problem. For example, there is a serious failure of the hard disk itself. It is recommended to replace the hard disk and try again.
Basically these common ways of handling it. Although it seems that there are a lot of steps, most of the situations revolve around the core points of USB disk, disk status and driver. As long as you check step by step, the problem can be solved most of the time.
