However, it also happens when updating Windows 10 to a newer feature build or upgrading Windows from 7 or 8.1 to 10 through a bootable drive<\/a>.<\/p>\n After the installation begins, but before most of the Windows files have been copied to the PC, the process suddenly stops and displays a white background with the following error message:<\/p>\n Going by an article by Windows support, the error code 0x8007025D stands for ERROR_BAD_COMPRESSION_BUFFER<\/em>.<\/p>\n We won’t bore you with the technical jargon. Suffice it to say that this error signifies that an error occurred somewhere during the decoding of the installation data, forcing the process to stop.<\/p>\n Why does the 0x8007025D error occur, especially during Windows 10 installation via a bootable USB drive? There are several possible reasons:<\/p>\n Also Read:<\/strong> How to Run Hard Drive Diagnostics on Windows PC?<\/a><\/p>\n Also Read: <\/b>How to Check How Much RAM You Have on Windows 10 PC and MAC<\/a><\/p>\n The rest of this guide deals with how to fix the “Windows cannot install required files” error. You may have tried some of the fixes described here before, so you can simply jump to whichever solution you think is likely to work for you.<\/p>\n The first rule of installing anything on a computer is to make sure that all possible causes of interference are removed.<\/p>\n These include all connected peripheral devices, such as extra USB sticks or Internet cables. Try removing them all before you redo the installation.<\/p>\n If you are installing your OS from a bootable device<\/a>, Windows copies all the files from the USB flash drive or disk to the computer and then continues the installation process from there.<\/p>\n If the 0x8007025D problem only appears after a certain advanced stage of the installation, you may unplug your USB drive and see what happens.<\/p>\n Chances are it isn’t needed anymore and the rest of the installation process will proceed without a hitch.<\/p>\n The second rule of installing anything on a computer is patience. Patience takes many forms here. It may mean waiting a long time for the installation to be completed without abruptly canceling it or thinking the process has been stuck.<\/p>\n Another form is attempting it again if it fails the first time.<\/p>\n The 0x8007025D error may just be a glitch that isn’t linked to any big underlying issue. A reboot and another attempt might be all that is needed to successfully install Windows.<\/p>\n So, if you get the error during your first try, don’t be discouraged. Give the installation process another go before you delve into the rest of the fixes given in this guide.<\/p>\n If you are still looking for how to fix the “Windows cannot install required files” issue in Windows 10 after trying the above methods, the Windows Update Troubleshooter<\/a> can help.<\/p>\n You can only run this troubleshooter if you are merely updating Windows with a feature build rather than doing a clean install.<\/p>\n Finding and using the Update Troubleshooter in Windows 10 isn’t hard. Just follow these steps:<\/p>\n If you’re seeing the error while trying to run a feature update on Windows 11, these steps will help: <\/p>\n The Windows Update Troubleshooter will launch and try to figure out what the problem is. After it is done with the scanning, pay attention to whatever recommendation it makes and follow it.<\/p>\n Try Auslogics BoostSpeed today for a faster, more stable Windows experience!<\/div>\r\n The 0x8007025D error usually occurs during a clean installation<\/a>.<\/a> <\/strong>During the installation, there comes a stage when you select the partition you want to install Windows on.<\/p>\n The ideal Windows 10 installation space needed is no more than 20 GB, while Windows 11 requires at least 64 GB of free storage . <\/p>\n Of course, the system partition is usually way larger than that. However, if you keep getting installation errors no matter what you do, you can try reducing the size of your installation partition to around 125 GB.<\/p>\n The larger the size of the partition is, the higher the chance that the space you are copying the OS to is corrupted.<\/p>\n As such, reducing the installation partition’s size is one way to get rid of the 0x8007025D error during Windows 10 installation.<\/p>\n This option isn’t available if you are installing a feature built on an existing installation. However, you can configure the install partition during a completely clean install using bootable media.<\/p>\n On the “Where do you want to install Windows?” screen, after choosing Custom installation, select your installation partition and click the Extend option.<\/p>\n Of course, this will not be effective if your hard drive or SSD<\/a> is corrupted or damaged. Thus, first of all, format the internal storage before you extend the installation partition.<\/p>\n Related:<\/strong> Ultimate<\/a> Guide: How to Partition a Hard Drive<\/a><\/p>\n Your BIOS<\/a> may be too old and in need of an update. It may not be able to keep up with the new tech in Windows 10, which is why the system returns errors like the error code 0x8007025D problem during installation.<\/p>\n Several users claimed updating their BIOS solved the issue completely. The theory goes that bringing your BIOS to the latest version equips it with everything it needs to work smoothly with Windows 10.<\/p>\n If your BIOS is old and an update is available for it, there is no reason for you not to quickly install it.<\/p>\n Remember that updating your BIOS<\/a> is needed only in extreme cases. If your BIOS is current enough, or if you haven’t exhausted all the possible solutions, you don’t have to do it.<\/p>\n First, check whether a BIOS update is available for your PC:<\/p>\n This is the most common method of installing the BIOS on most modern PCs. However, if the BIOS download package contains a Readme file, consult it and follow the instructions in it.<\/p>\n After you have done the update, retry the Windows 10 installation. Hopefully, nothing will go wrong this time. If the 0x8007025D error still shows up, try the next solution.<\/p>\n Download a Fresh Windows 10 Image File <\/strong><\/p>\n There is a chance that the ISO image you’re trying to install contains a corrupt file. That corrupt file may affect everything else and give rise to the current error.<\/p>\n Faulty files often cause decoding errors. The system is unable to read a faulty file, especially if it is an important system component.<\/p>\n Another possibility is that a certain file is missing. Files can sometimes disappear from a Windows installation image. Without these files, of course, the installation may not even be able to start, never mind be completed.<\/p>\n To solve the current error, you may need to download the Windows 10 ISO file again before you retry the installation.<\/p>\n If the error indeed results from a corrupt or missing file, downloading a fresh image will likely solve the issue immediately.<\/p>\n Go to the Windows 10 download page<\/a> and redo the download. If you’re installing Windows 11, go to the Windows 11 download page<\/a> instead.<\/p>\n Follow the instructions to create a bootable USB drive. Then, go ahead and try installing Windows again.<\/p>\nThe installation was canceled \r\nAny changes made to your computer won't be saved. \r\nWindows Setup \r\nWindows cannot install required files. Make sure all files required for installation are available, and restart the installation. Error code: 0x8007025D<\/pre>\n
