In this tutorial we are going to try to fix the problem of the constant restart of Windows. This can happen for a range of reasons, but I hope you remember the most likely situations.
The first two parts of this guide will talk about how to fix the error if Windows 7 restarts only after startup screen for no apparent reason, in two different ways. In the third part, we will talk about another common case: when after installing updates, the computer restarts and later says to install the updates again, and so on. Then, if you have this variant, can go directly to the third part. See also: Windows 10 write Failed Updates and Reboots.
Automatically restore Windows startup 7
This is probably the easiest way to test when Windows 7 restarts at boot. Despite this, Unfortunately, this method rarely helps.
Therefore, you will need a Windows installation disc 7 or a bootable flash drive, not necessarily the same from which you installed the operating system on your computer.
Boot from that drive and, after choosing your language, click on the link “Restore system” displayed on the screen with the button “Install”. If asked “Do you want to reassign the drive letters to match the target operating system mappings?”, Reply “Yes”. This is especially useful if this method does not work and the second method described in this post is used.
Additionally you will be asked to select a copy of Windows 7 to restore: select it and click “Next”.
The recovery tools window will appear. At the top it will read “Startup repair”: This feature enables you to automatically correct the most common errors that prevent Windows from starting regularly. Click on this link. Then you just have to wait. If the result will be a message that no startup problems were found, click on “Cancel” O “Cancel”, we will try the second method.
Solve the reboot problem by restoring the registry
In the recovery tools window that was launched in the above method, run the command line. You can also (if you didn't use the first method) run windows safe mode 7 with command line support; for this case, no disk is needed.
Important: I do not recommend any of the following for new users. Otherwise, it is at your own risk.
Note: Note that, then, the system partition letter of your computer's drive may not be C :, in which case use the assigned.
On the command line, type C: and press Enter (or another drive letter with a colon; the drive letter is displayed when the operating system is selected to restore if you are using a disk or flash drive with the operating system layout. When using safe mode) , if I'm not mistaken, the system drive will be below the letter C :).
Enter the commands in order, confirming them when necessary:
CD windowssystem32config MD backup copy *.* backup CD RegBack copy *.* ..
Look at the colon in the last command: They are mandatory. Just in case, what these commands do: first we go to the system32config folder, later we create a backup folder where we copy all the configuration files – we save the backup. Subsequently, We will go to the RegBack folder where we save the previous version of the Windows registry 7 and we copy the files from there instead of the ones the system uses today.
Once this is done, restart your computer; most likely now it starts regularly. If this method did not help, I don't know what else to recommend. Try to read the Windows post 7 does not start.
Windows 7 reboots non-stop after installing updates
Another variant that is also quite common is that Windows restarts after the update, reinstall X updates from N, reboot again and so on ad infinitum. In this circumstance, try the following steps:
- Go to command line in system restore from bootable media or run safe mode with command line support (the previous paragraphs describe how to do this).
- Type C: and hit Enter (if you are in recovery mode, the drive letter may be different, if in safe mode with command line support, will be C).
- Entered cd c: windowswinsxs and hit Enter.
- Come in . of slope.xml and confirm to delete the file.
This will clear the list of updates waiting to be installed and Windows 7 should start regularly after reboot.
I hope this post is useful for those who have encountered the problem described.
