Clean Windows 10 install fails on SSD fails with error code 0x8007025D

Yesterday I tried installing windows 10 on my SSD with a bootable USB stick for windows 10, created with Rufus.

However, no matter what I try, i always get thrown out at ~32-40% of the second installation part, "preparing files for installation"

Everytime I am greeted with an error code of "0x8007025D", without any further explanation what could be wrong.

I tried redownloading a fresh iso file a few times, but that doesn't seem to make any difference at all. However, I also tried running the installation on a VM, it seems to work there without error code, so it might not even be the iso.

Could either my stick or Rufus be causing this behaviour?

Solution:

Format the primary drive partition before installing the OS.

I had exactly the same problem when I tried installing a Windows 10 ISO on a new Lenovo G40-45 laptop using the same Rufus tool. The problem was I didn't format the primary drive and I got this same error code 0x8007025d. Once I did the formatting before selecting it as the primary partition to install the OS on that partition, the windows files loaded without any errors. Hope this helps.

In my experience the ISO file was corrupt. Download a new one using the Media Creation Tool.

I encountered this problem yesterday, and I would like to post my solution here just in case other people may have similar issues. Since I was reinstalling Windows 10, I can confirm the hardware is all in good condition. But I still get the error code 0x8007025D. The error code itself is not quite descriptive. Most of the posts online refer it to a hard drive or installation media corrupt. But if there is a hardware bug, at least the motherboard should tell me. I did not get any errors from the motherboard diagnosis.

Then, I thought it could be a memory bug. I cannot remember where I get this hint from. So I removed all the memory sticks and left only one slot occupied (I had four 8 GB memory sticks, so only 8 GB mem left). Then the problem was magically solved. To confirm it is the culprit, I plugged in the other memory sticks again and did another installation. The error code 0x8007025D pops up again. If I use only one memory stick, I can successfully install the second Windows 10. Although I don't know the root cause of the problem. But if you encounter this problem, try to remove some memory sticks before installation, and plug them back after you succeed.

Probably, my solution is limited to specific hardware. Here is my hardware as a reference:

  • Motherboard: ASUS Maximus X
  • Memory: 8 GB Corsair 3200 MHz x4
  • Hard drive: Samsung 970 Pro 1 TB x2
  • CPU: Core i7 8700k
