Although it is believed that the installation of Windows is fully automated, unfortunately, a lot of users are faced with situations when installing Windows 7 gives an error. What is most sad, this can be observed both when formatting a hard disk or logical partition, or when the installation process is already running.
Why, when installing Windows 7, gives an error 0x80070017?
We will say right away that although Windows 7 in different versions and assemblies is universal, so to speak, “tuned” to the classics, nevertheless, many users have different difficulties installing it.
Unlike the same version of XP, even the presence of an original disk with an installer and all drivers does not guarantee the successful installation of the "seven" on a computer or laptop. The fact is that the installer initially contains some settings, without which the OS on the hard drive simply will not get up. When installing Windows 7, it often gives an error even at the initial stage. Why - we are now trying to figure it out.
Problems reading data from optical discs
As it has already become clear, we will proceed from the fact that the installation distribution kit is located on optical media in the form of a DVD-ROM. We make a reservation right away, he does not fit on a regular CD, so if you come across such a disk, you can safely throw it away. It will miss many components, at least the driver database for sure.
However, returning to the question of why it produces an error when installing Windows 7, it is worth immediately looking at the state of the disk. Who knows, maybe there are scratches or cracks on it, due to which reading installation files is impossible.
On the other hand, the problem may lie in the drive itself (DVD-ROM drive). If for some reason it does not accept the disk or an error is generated during the installation process, it is very likely that the read head is damaged. Yes, and drivers may not always work correctly.
What to do? Everything is simple: either replace the drive, or create a bootable flash drive and try to install from it. There are enough programs to create installation USB-drives today.
Winchester Modes
However, even in a situation with an undamaged medium, a situation can also be observed when during the installation of Windows 7 it gives an error at the stage of formatting or copying data.
This is due, in particular to Windows 7, also due to the fact that the installation process itself cannot get correct access to the hard drive. In this case, you will need to enter the BIOS and switch the operating mode of the SATA controller from AHCI to IDE.
In some situations, when the installation is more or less successful, the problem that an error occurs during the installation of Windows 7 may be due to the presence of incorrect boot records. We will not delve into the subtleties. But you can advise you to use bootloader recovery during installation by applying the bootrec / fixmbr combination on the command line called by the Shift + F10 key combination.
Update errors
With updates, the situation is somewhat worse. Even in this case, installing Windows 7 gives an error.
Here you can do different things: either turn off the automatic update in general in the "Update Center" (standard "Control Panel"), or there is a more effective method. It consists in the fact that in the command line, called either from the main menu in the "All Programs" / "Standard" sections, from the "Run" menu by entering the abbreviation cmd, or from the Windows Recovery Console on the original disk (which is preferable), register the following commands: first net stop wuauserv, then CD% systemroot% \ SoftwareDistribution, then Ren Download Download.old, and finally net start wuauserv. After that, the update should happen without problems.
Total
In conclusion, it is worth saying that when installing Windows 7, it gives an error not only in the above described situations. There can be a lot of problems. In the installation process itself, it is necessary not only to install the system, but, as practice shows, additionally download and install the drivers of all devices. In particular, this applies to the maximum Russified version, which can be found, so to speak, in a “cracked” form without the introduction of license codes and subsequent activation.
