Windows 10: failed during clean install Error Code 0x8007025D

Thanks for your response, Starlord! For me, it turned out that the ISO I was burning from was corrupted. I re-downloaded, re-burned and then it worked fine

 

The customer was using a wireless mouse from MS and I need to remove the USB homing adapter for the installation to go forward. This is when trying to install Windows 10. I am now trying to install Windows 7 after the adapter removal to see if that work first...thanks to MS licensing.

 

I had a customer that brought me a PC that the hard drive had crashed on. He had purchased a new hard drive, and wanted me to load Windows 10 on it. Every time I started the install, at the "Getting files ready for installation" step, the PC would pop-up an error with 0x8007025D error. Exact error said:

“Windows cannot install required files. The file may be corrupt or missing. Make sure all files for installation are available, and restart the installation. Error code: 0x80070570.”
I spent the better part of the day troubleshooting until I narrowed it down to bad memory modules. I changed out the RAM and it installed without a hitch.

I know this is an old post, but I wanted to share my experience in hopes that it may help someone else.

I reached this solution after deciding to try installing Windows 7 instead of 10 (that is what the original hard drive was running) and that install crashed with the same error. I dug through Internet forums and found all sorts of suggestions to fix this issue - everything from reformatting/replacing the hard drive (this was a brand new 2TB hard drive, and I had tried two other known good hard drives) to updating the BIOS (already done).

I finally stumbled on a site that suggested this error is caused by a memory misconfiguration, and suggested leaving only one stick of RAM in the first slot on the motherboard and trying again. Since I had extra memory on-hand, I just replaced both memory modules and tried again, and I was able to install Windows 10 without issue.

 

I had the same error code 0x8007025D.

I have removed all optional devices (mouse, DVD, one of the 2 RAM) but the problem was still there : same error code after 29% of installation.

I finally created again the win 10 usb installation from another computer and tried again, and it worked.

(Maybe removing all optional devices was not required... I can't say, but for information, I had them all removed during the install.)

I've been a software professional (now retired) since 1975. I have installed VAX/VMS, Ultrix, Unix, Linux, OS/400, and various other operating systems and complex software packages. I have also been working with Microsoft products since DOS 4.11. Nothing has given me as many problems as Microsoft products. I have NEVER had a so-called upgrade work without doing a clean install, and even then, it's rare that there wasn't some grief involved. Disassemble my machine to install their bloody "upgrade"? Not likely! As it is I've wasted a week on this POS, and wound up having to reinstall Win 7, after reformatting my main drive. Now, having that damned "upgrade to Win 10 icon in my tray just adds insult to injury. For the record, I tried the automatic upgrade method, the USB method, and burned an ISO image to disk. Were it not for a substantial investment in critical application software I would simply move to Ubuntu (Linux), so I'm doing the next best thing: I'll keep this machine, with Win7 for running my essential applications, and build a new Linux system for all other use. I absolutely refuse to send another dollar to a company with such a dismal record of customer 'service'. Maybe MS thinks they're too big to fail, but as far as I'm concerned, they're just too indifferent to support.

 

I believe I have solved the problem. I attempted a fresh installation of Windows 10 on to my brand new "OCZ Trion 150 480 GB SSD". This resulted in the error, "Windows cannot install required files. Make sure all the files required for installation are available, and restart the installation. Error Code: 0x8007025D".

After reading many FORUMS, this one included and trying all the various suggestions, nothing worked!

I borrowed my son's Kingston Hyper X 250 (125 GB SSD), and ran a successful installation with no errors. This PROVED that my installation media which I created using Microsoft's media creation tool was just FINE. It also proved that nothing was wrong with my hardware. I suspected that maybe it was a bad SSD that I had. So I went out and bought a brand new "Corsair Force LE 480GB SSD". I ran an installation, this resulted in the error, "Windows cannot install required files. Make sure all the files required for installation are available, and restart the installation. Error Code: 0x8007025D".

So could I possibly have TWO BAD SSD units? No, not at all... I remembered that my son's SSD was a small volume 125GB drive. So on a hunch I did the following:

• So I placed my SSD (Corsair) in an external enclosure, connected it to my laptop, formatted (not Quick Format, but Full Format).
• I then created two partitions, Vol1 (125GB - primary) and Vol2 (355GB).
• I then opened DISKPART and did a CLEAN and then I CONVERTED the volume to MBR from GPT.
• Next I mounted the SSD back in to my PC.
• I Reset my BIOS to Factory Defaults just to be safe.
• I Ran the installation on the 125GB partition.
• WINDOWS 10 installed just fine.

So this means that neither of my SSDs were bad, it means Windows 10 FREAKS OUT when installing fresh on large volume SSDs. Possibly anything over 250 GB.

Good luck! *Cool

FYI... How to do DISKPART

1. Type Diskpart, press Enter
2. Type List Disk , press Enter
3. Type Select Disk # (where # is the number your drive shows up as), press Enter
4. Type Clean, press Enter
5. Type Convert MBR, press Enter
6. Type Exit, press Enter.

 

Installing from USB, I was given 2 options, I chose Windows 10 PRO. It failed quite quickly with Error Code: 0x8007025D.
After much endeavour, unable to go back to Win7 Home Premium. (Bootmgr missing) , I tried again and chose Windows Home.
I did not know at the time that this was my only option.
It now appears to have installed correctly, I am at "Getting ready"
Thanks for all the tips and advice given on here.

 

Just installed it on a 500GB Sandisk SSD and a 1TB Evo SSD so not a large SSD problem.
Still who knows what really fixed your problem since Win10 is still as buggy as any Windows OS I've used before since Win 9.x
I got this particular

• Error Code 0x8007025D
  
  

when having a USB stick plugged in. So guess there's still a use for the good old DVD drive since I had to use that to do a successfull clean install. No matter what USB port or USB stick I tried Win 10 installer didn't like it. I figured as much because always had problems with earlier versions of Windows too so learned early on to disconnect all external devices except keyboard and mouse during install.


Don't know why I torture myself with Win10 when Win7 had no problems installing to same drive/setup. This is my second time installing Win10 on this rig since first time I did it with all my other 6 internal drives disconnected for cleanest install and after I had it up and running reconnected all the rest of the drives and of course Win 10 refused to boot giving inaccesible boot device cuz it got confused with all the new drives and I tried to fix it using bcdedit, bcdboot, etc and none of it worked so 2nd time I installed Win10 I did it with all my 6 drives installed and just wiped the original 500GB SSD clean and that's when I got error mentioned here.

 

Thank you for the tip. Installed smoothly right after I replaced one of the RAM sticks. Unreal.

 

Not really, ever since Win7 it's been pretty picky about memory. I remember reading somewhere on Microsoft website a while back they did this on purpose because they'd rather have your machine crash or not install at all if it detects bad RAM.

 

Same here... it's the RAM. If there are hardware issues, run RAM test first using Memtest86... with both 4GB sticks in, it popped up errors galore... took one out and went away... put a different 4GB stick in and no errors... after that, Windows install smooth as butter.

Noticed it MANY times... if Windows 7+ fails to install, it's hardware issues... so you have to run some tests for them. Usually it's hardware faults that cause it to not install.

 

Ok, for everyone here, no offense, just saying. Don't say that it's definitely RAM or size or anything, just because it can be anything from hardware failure to stars position.

For me it was too large disk partition.
I did everything that came to my mind after I got this error.
First I tried with one RAM stick - Nothing
Tried another HDD - Nothing
Re-flashed the memory card that I used - Nothing
Changed all my sata cables (PSU and data) - Nothing
Then I came here to read that thread and saw @afsanchez001 's post about disk size.
Went back to installation, made 125Gb sized partition to my disk. Vo'ila, installation ran through succesfully without any issues.

If I may suggest something for OP or moderators, that would be pinning possible solutions to first post, just because this thread is first that comes up when searching that error from google. I would personally start with that disk partition solution.

Like that:

Possible solutions for error code 0x8007025D:

1: Make sure you have made disk partition for OS during install you can do that either before install in disk management or during the install in screen where you can see your storage drive devices.
Make the primary drive that big that you cannot run into running out of space problems, but I personally don't recommend using more that 150Gb (if 150Gb is too much, try 125Gb). MAKE SURE THAT YOU HAVE "PRIMARY" AND "SECONDARY" partition before proceeding to install.

2. Make sure you don't have any hardware failures.
Make sure that your storage device is not faulty
Try switching RAM sticks to different DIMM's or launching with only 1 RAM-stick.
Keep only that drive connected where you are about to install OS. That prevents wrong files to end up to wrong places.

Hello everyone,

I've signed up to this forum just to tell you I've found a very curious way to finish the setup process. First about my environment:

I've tried to install Windows 10 (version 1607, build 14393) on a Intel NUC with a 128 GB SSD. The SSD was completely blank. I created an installation medium using the official Media Creation Tool from Microsoft. I've used a 32GB USB 3.0 Flash Drive from Transcend.
When I tried to install Windows from that flash drive on my blank NUC it failed with the error 0x8007025d. I've checked my RAM, replaced it with another one. Still same problem.

Now my idea was to see what happens if I try to boot up my computer normally by removing the flash drive. Well, the setup continued at the point where it asks which settings it should use (express or custom settings). About two minutes later I saw the Windows Desktop. YAY!

I still have no idea what the problem really was but I think the setup process from the flash drive has problems to read the data from the SSD. But since the setup process already copied it to the SSD you can directly run it by booting from there.

Hope this helps at least some of you.

 

Do you have any USB 2 ports? If so, maybe using one of them would make a difference. It has for others.

 

No, I only have USB 3.0 ports. But I also don't want to test it, now that it works. It's my productive system.

But interesting that this can make a difference too.
