Preferred Solution: windows 8 cannot install required files error code0x8007025d

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


This is what is happening. A friend gave me his DELL Inspririon 531 2007 Desktop. It has a pirated copy of 7 ultimate x64 (which I am not sure if this supports 64 bit). Prior to looking into how old the machine was, I was able to install 8.1 64 bit. But it wouldn't allow me to install any drivers from the DELL site. Said that the machine wasn't compatible. So, I tried with Windows 7 32 bit and I am getting this error. I have deleted all partitions, but now, I do not have that option when I choose Custom-advanced. There is no Delete option.

A few times I got the error at 5% other times at over 60%. What can I do to get this to install? It is a legit DVD of windows. Why would it have allowed 8.1 to successfully install now it is doing this? What files are missing? I have tried both deleting the partitions and not deleting. Same result.

A:Clean install error Windows cannot install required files.

Install the correct version of windows that`s on the COA, either buy a new installer from Newegg or call Dell for Recovery CD`s.

The dvd you are trying to use is corrupted and no good.

I have been trying to do a clean install of windows 7 and I am now getting this message. I have probably done a clean install using the exact same disk 5 times before. I've tried formatting the hard drive and re partitioning. This is a custom build.

The thing that is interesting to me is that I then tried to do a clean install using a vista disk that I have, and I get a similar message.

However I am able to install Xp pro just fine. I've also tried switching out memory as well.

Any suggestions would be appreciated.

I bought a new SSD and want to do a clean install on it, however am having problems during the install process and receive the following message:

Windows 8 cannot install required files. Make sure all files required for installation are available, and restart the installation. Error code: 0x8007025d
The install images was downloaded from the Microsoft website and I have tried using a USB thumb drive and DVD install disc and both receive the same error. I have used the DVD disc when I originally installed Windows 8 Pro on the same desktop but on an IDE harddrive and believe the disc should still work (i.e. no scratches on it).

Here's how I prepared to install:

1. Unplugged all harddrives except for brand new SSD (Crucial M4 128 GB SSD)
2. Changed bios settings to AHCI (before was on IDE) (using Asus P5k-V motherboard)

I'm not sure what's going on if the harddrive is corrupt, the bios settings need to be tweaked, the drive is incompatible with my motherboard or something else.

Any help would be much appreciated as I don't want to go back to using the IDE drive to boot windows but rather use the new SSD.

Hey guys!

I have a new ASUS ROG G751JT-DH72 laptop, and I have been trying to install Windows 10 and Ubuntu on it. It came with Windows 8.1, so I upgraded to 10, then did a clean install of 10. Version was Home 64 bit.

That went reasonably well: only thing after the clean re-install was that on boot, the screen did nothing but flash on and off. I found out that I could get it unstuck by mashing F12, and that disabling fast boot fixes the problem permanently. My cleanly installed fresh Windows 10 worked perfectly.

I then installed Ubuntu 15.04 in the small space that I had left for it on the SSD, and gave it the whole 1 TB drive for my "home" folder.

Afterwards, Windows was gone. Mind you, the bootloader still showed up in the Grub menu, but when I tried to launch it, it told me something was wrong and I had to recover it. I tried, but couldn't: bootrec /scanos told me it found no Windows installations.

So I figured: second attempt! I rebooted using the Windows 10 DVD, and during parititioning nuked everything and created new partitions from scratch.

About 90% through the "Getting files ready" part, it failed. Error:

"Windows cannot install required files. Make sure all files required for installation are available, and restart the installation. Error code: 0x8007025D"

I see some people here had the same thing, but not on laptops as far as I can tell. Anybody out there who has any idea how to fix this? I tried:

Hi everyone

I've built a brand new PC and decided that I would like to install windows 7 64 bit on my SSD, I got a disk+key from my university before christmas so that'd i'd be ready once i'd built it.

I built the PC yesterday and realised that I'd left my external DVD drive at my university accommodation, I'm at my parents house for christmas break so that's a few weeks left. I can't really wait that long so I used my parents laptop (which I'm posting from now) to turn the disk into an .iso and use the microsoft USB utility to make a USB stick that i could install from.

However when I tried the install gets to 'installing features' and gives 'windows cannot install required files' error code 0x80070570 I looked the code up on google which sent me to a lot of threads here, so far I've tried:

Taking all but 1 stick of ram out and the graphics card.
Reseting the bios to default
Installing again without rebooting after error.
using cmd to select the right partition

Nothing has worked, please help me I'm losing my mind

Hey guys, im trying to do this (i have windows 7 installed first) but when installing vista, at just 2% i get this Windows cannot copy files error. Im installing from a bootable USB and i've already tried using a different 4gb usb, a different vista iso file, different programs to make my usb bootable and different partition configurations.

Where did you get Vista? Check the HASH against official HASH.

Perhaps you can borrow an external DVD drive to try install.

I'm assuming you don't have a DVD drive or you wouldn't have gone to all the effort to try different USB writing methods. The one which always works for me is UltraISO trial version: Open ISO on file tab, Write Disk Image on Bootable Tab, Format, Write. Then boot under USB or HD's.

If this fails, I'd reset the BIOS CMOS: Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS

If this is a PC do you have another HD to try install upon? If so unplug Win7 and wipe the target HD first. Then after install plug back in Win7, boot preferred first in BIOS, then boot the other using BIOS Boot Menu.

hi there, this question may of been asked elsewhere. What files and folders does Windows need to run? That doesn't include Microsoft Works/Office, just THE basic things that are needed for Windows to actually 'be alive'.

Not to avoid answering your question, which at first seems a rather simple one to answer but turns out to be somewhat complex, but why are you asking this question?

Deploying a Windows 8.1 Enterprise image on Dell Venue 11 (5130 atom version)
Created an UEFI FAT32 USB drive (http://rufus.akeo.ie/?locale=en_US)
I replaced sources\install.wim with a customized Windows 8.1 image.
The customized image is 4,6GB large so i had to split it into 2 .swm files because of the FAT32 4GB limitation.
Setup is starting and when i want to install, the following error occured and i have to cancel the installation.
"Windows cannot find the Microsoft Software License Terms.  Make sure the installation sources are valid and restart the installation"
is there a file which points to the license terms that i can modify or something like that??

A:Windows 8.1 install from USB with multiple swm files license terms error

Hi MartinOtter,
Windows 8 and 8.1 Setup does not support split .wim files, so this might have been the original problem. The TechNet article "Split a Windows Image (.swm) File to Span Across Multiple DVDs"
has this note:
In Windows 8.1 and Windows 8, Windows Setup does not support installing a split .wim file.
And later it states:

You can apply the file to your destination computers only by using the /Apply-Image option in the DISM tool.

If you are still having issues with this deployment while using a .wim that isn't split, can you
check the log files?

Hope this helps,

I have an Aspire 5742 with Windows Home Premium. I have just replaced the hard drive as it would no longer start up. I made a drive backup some time ago using Acronis True Image after the laptop was setup with all my programmes. After I installed the new hard drive I ran the Acronis recovery to copy the drive backup to the new hard drive and it reported complete but when I try to boot the laptop it says bootmgr is missing. So I need to now repair the Windows 7 installation but Acer only supply a factory default option not a Windows 7 installation disc. I don't want to do a factory default as I have a programme installed that will cost $200 per hour in support fees for the software vendor to re-install it again. I contacted Microsoft about getting a Windows 7 disc but they said because it is OEM I have to contact Acer. Between the two of them they sent me around in circles until it was established that neither of the two companies could help me. So what do I do now please?

Hey there,

I just got my notebook back from support since my harddrive failed last week.

So, since I'd have to reconfigure everything anyways, I'm thinking about installing Windows 8.1, which I can get through a student program of my university.

The preparation stops at the drivers, though, since I can't find any drivers for Windows 8 and my model.

Note that my model is an L650-1L4 and was originally shipped with Windows 7.

Has somebody here maybe some experience with this?
Are the generic drivers included in Win8 sufficient to be able to work - and play games - flawlessly?

While I could easily wipe the Win8 installation and reinstall Win7 again, I like to be prepared, and since I'm leaving this weekend for a small vacation, I'd like to have a working notebook with me.

Thanks for your help!

Hmmmmm...... it can be a bit complicated. I?ve checked Toshiba download page and your notebook model is not supported for Win8. I?ve checked some other models with similar hardware configuration but they are not supported for Win8.

I really don't know what to say. If you have created recovery disc (Win7) install Win8 and check how it works. Some Toshiba specific tools and utilities you can download from other models in hope everything will work well.

Anyway I think you should stay on Win7.

I have a known working image of Windows 7 on a flash drive.

However, if trying to install Windows 7 by booting from the flash drive I get "a required cd/dvd drive device driver is missing usb"

I have tried removing and reinserting the usb.

I found a link https://downloadcenter.intel.com/dow...reator-Utility

that is supposed to put the drivers for usb 3.0 in the installation files. That did not work.

I have tried downloading the usb files from the manufacturer Acer for usb 3.0 and then navigating to them via browse and found files that showed up, but that did not work.

I also tried installing drivers for AHCI, CardReader, Chipset by clicking browse and navigating to the hard drive. All to no avail.

I am now going to see if putting the USB driver files on the flash drive will work. Would this make a difference? And should I potentially try this with the other driver files as well?

I used DBAN to wipe my hard drive and i forgot to back it up. I do not have the CD for Windows 7 installation, therefore I created a bootable flash drive for Windows 7 64bit. I can't figure out what drivers is needed to continue on the installation. It says: "a required CD/DVD drive device is missing. If you have a driver Floppy Disc, CD, DVD, or USb Flash Drive, please insert it now."

Here is the information on my laptop I retrieved off the website.

Hi guys, I'm trying to install the 32 bit version of 7 on my toshiba m700. For the past half year or so, I ran the RC just fine with no trouble. Then all of a sudden, my computer shut off and when I would turn it on I got a disk read error. The ITS department at my school reimaged the computer with XP, and it worked. Since then, I've tried to reinstall 7 doing a clean install, but everytime the computer says "cannot install requiered files.". I'm certain the iso is not corrupt: I've tried a cracked version, the enterprise trial, and the iso I downloaded for $30 with the student discount. I've tried burning a DVD and booting off a flash drive multiple times. Every rime I get the same error. I have 1 hard drive and 1 DVD drive attached; I don't know what kind they are. I also heard that removing ram may solve my problem, I'm wary of doing that because it may void my warrenty and then my school's ITS department may not service my computer anymore: they don't like me running 7 in the first place. I ran the RC fine, why can't I install the real version? If all else fails, I could reinstall xp, which does install without errors. I'd really appreciate the help.

A:"Cannot install required files" -- Tried everything

When exactly does it throw up the error? What is the exact wording?

Try running the Win7 installer from the Xp desktop, if you haven't done so already.

If you ran cracks on that HD, then you may need to use DBAN to nuke the HD for the deepest clean.

Then try booting the WIn7 installer for custom install again.

Boot into BIOS settings and see what the SATA controller setting is. Try AHCI first.

Do you have another laptop? Sometimes rather than spending days of frustrating endless troubleshooting, someone who is tech savvy can just snap the HD into another laptop and install there, then return to your machine to enjoy the show as it swaps out all the drivers, requesting restarts. It has worked a dozen times for me.

If you do this, wait to activate until you get it back into the old machine and reaclimated to the hardware there.

I have noticed this issue today.  When I was moving some files from my phone to my laptop, it displayed the message "calculating the time required to copy the files," loaded more time than it should have, and then did the transfer. This has never happened before.  It normally just jumps right into the file transfer process without that delay.  Does it have something to do with the amount of files in a folder or something else, because I just dd a transfer of two zipped files and they did not display that message.  Can someone explain why my computer displayed this message?
Windows 7 (64-bit)

A:annoying "calculating the time required to copy the files message" on windows 7

Yes - you are correct, it is the quantity of files. As far as I know, it will do this for one little text file as well, but since the time taken for the calculation is so short, the message doesn't have the time to show.
Obviously, since the time taken for calculation depends on the amount of data, there comes some critical level when the time is long enough for the message to show. You get the same thing when moving files between drives inside the computer. Internally, on my own computer, it seems to be about 250Mb.

Hi all

Hope someone can help me

My windows 7 hdd will not boot up. I get an error message saying:

The boot selection failed because a required device is inaccessible

Now I have tried startup recovery several times with no luck.

I have tried bootrec.exe and tried to rebuild it but no luck

I have tried to use the recovery disks I made when I first bought the laptop but it doesnt allow me to select the repair windows files and preserve files options. It allows me to select the fresh windows install option however when I do it it always fails and says a path cannot be found.

I have tried the chkdsk/r in command prompt to fix any problems and that was successful but still no luck.

here is a screen shot of my disk management, it is disk 1

I just need access to my files on there. I have tried to mount it via acronis so it works as an ordinary disk but it doesnt pick it up

Please could someone help

Hi, I just bought a brand new HP 17-x018NG and the OS is Windows 10, I don't like this OS and I tried to install Windows 7 Ultimate, I followed the steps that I found on this forum (Legacy Support : Enabled ; Secure Boot : Disabled etc.) and when I click on Install Windows this error appears : A required cd/dvd drive device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now. I saw that I must change the USB to Auto but I don't find any USB option in BIOS. Can you please help, I don't know what to do. Thank you!

h guys

i have two computers (1 pc and 1 laptop) that i am putting windows 7 ultimate on. i have a key each for the pc's but not the original disk. i have previousley downloaded a windows 7 disk that worked great. installed straight away on the both systems. both pc's now have viruses due to my mother and brother lol. so i dug out the windows 7 disk today and it's been scratched beyond repair. so i had to download the disk again. however i cannot find the exact download that i had last time but i have tried two seperate dowloads and when trying to install each one i get the error message " required cd/dvd drive device driver missing" it's so frustrating as i know windows7 will install on them as that's what they're running now. does anyone have any ideas what it could be.

thanks in advance

Hi -

You need a genuine Windows 7 DVD.

Contact Microsoft --> http://support.microsoft.com/kb/326246

If OEM version, contact system manufacturer regarding replacement media.

After genuine Windows 7 DVD is obtained, wipe the HDD with KillDisk and reinstall Windows 7 -

I have been given the incorrect information on this forum and noticed that I have a file on my hard drive that is locked.

The person advised me to go to

Download Microsoft Visual C++ 2010 Redistributable Package (x86) from Official Microsoft Download Center

I have done this and it has come up with various screens that I am not familiar with.

It looks like it as uploaded to my USB External Hard Disk Drive.

Can some one please advise me the correct advice?

All that happened is that I got an error and the Windows Explorer crashed and then refreshed.

I'm really not sure what happened to my Windows Media Player; however, I DO have children/teenagers using the same computer - I may never know. My Media Player had been working and in the last week or so when attempting to play a song I receive an error message indicating Media Player is unable to run "due to a missing component".

I have uninstalled and reinstalled the program. (Interestingly, the first time I unstalled the program and re-booted - it was still there!?)
I have also made sure the PC is current with regard to Microsoft updates.
The machine is running Windows XP.

Any help would be greatly appreciated and I thank you in advance!

I've recently upgraded my windows 7 to windows 10 enterprise. I have onedrive account with files synced to cloud, before upgrading i've backed up onedrive files locally in my computer. Some of those files can't be opened after upgrade, formats include
.docx and .xlsx and .png. Most of these files were in direct onedrive main/root folder rather than in subfolders. As i can see those images in subfolders can be opened but not doc and excel files.

How can i view those files again, why have they become corrupt, what could I do in future to prevent these problems

I've been trying to install Windows 7 on my Asus Q501L (which came with W8 already installed) via USB. I faced a problem - while the laptop was able to start the initials steps (the black screen where it shows the copying process of the Windows 7 files), i couldn't go any further than the step at which i need to choose a partition to install the OS on.

It simply says " A required CD/DVD device driver is missing" - when you start Windows 7 or Windows Vista from the setup disk". I tried Shift-F10 to start the CMD and format the HDD (NTFS format) on the spot, restarted, same error message. I disabled Fast Boot in the BIOS, the SATA controller is set to AHCI. I tried several topics @ Tom's Hardware forum, and elsewhere but i still cant find a definitive answer.

I read that maybe i should change the AHCI controller to IDE, only issue i face is that in BIOS i get no options - there's only AHCI as a choice, no IDE, no RAID.
Any Ideas? How do i get IDE controller option to appear in the BIOS settings (via the registry keys, or maybe i need to download that IDE controller (not sure if thats possible)) from the Intel's website (intel core i5 is the CPU of my laptop if that's of any help)?

Thank you
