Windows installation Error code: 0x8007025D

Solved

Hello, I’ve looked at other topics with the same problem, I’ve tried everything… But nothing works, when I try to reinstall the Windows 10 ISO via a bootable USB drive, I always get this error message: “Windows cannot install the required files. Make sure all the files necessary for installation are available, and restart the installation. Error code: 0x8007025D”

Already, I’m not comfortable in this area, and now I don’t know what to do, especially since I can’t even use my PC because when I turn it on without the USB drive, I automatically go into the BIOS. I assume I no longer have an OS.

Hoping to resolve this issue as soon as possible!
Thank you in advance!

Configuration: Windows / Chrome 66.0.3359.117

Hello,

This error is quite common and often related to an issue with the installation media: Error 0x8007025D during the installation of Windows 10

It could also come from the USB drive used.

~~

If the USB drive doesn't work, try creating another one with Rufus: how to download Rufus.
Download the ISO file for example with Adguard: Download Windows ISO
Launch Rufus then specify the ISO file
In partition type, choose GPT.
For more details, refer to this tutorial for details: how to create a Windows installation USB drive

The Windows 10 installer should then start:

Follow this tutorial which explains how to install Windows 10: how to install Windows 10.
All steps are provided from A to Z with tips at the end to secure Windows 10.
  • Let yourself be guided to install Windows 10.
  • Choose custom (not upgrade)
  • During the partition phase, select the main partition and click next.


  • The installer will tell you that Windows is already present and offer to move it.


  • Follow the Windows installation procedure using the tutorial above.


Just don't format.

Your user data will be copied into the Windows.old folder.

Once Windows is installed, I recommend following these tips to properly configure and use Windows: Tips after reinstalling Windows.

First of all, thank you very much for your response, I will take the time to read everything

Just one question, I want to do everything right, should the USB drive be formatted in FAT32 or NTFS?

Hello

Test the memory with memtest or change it.

It works for me.
