Same error code here during clean install... I did manage to clean install it once this morning, but then broke it with Ubuntu.
Since then, have tried to clean install Windows 10 numerous times. Always the same error. Hardware is brand new, and since everything worked this morning, I have no reason to believe anything is broken... Hope anybody has any ideas!!
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.
“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.
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.
