When switching to a new version of an OS from Microsoft, it is quite natural to want to do this smoothly and consistently. If you are accustomed to the interface and functions of the seven, and want to take a closer look at Win 8.1 or 10, without deleting the seventh version that has already become familiar to you, this can be easily done. After all, based only on reviews, screenshots and opinions of other users, making a choice for yourself is sometimes not so easy. It’s worth looking at the new OS with your own eyes, and then deciding whether it’s right for you or not. If the new system turns out to be too heavy for the hardware configuration of your PC, or you simply don’t like it due to the presence of unnecessary functions or an overloaded interface, you can at any time return back to the operating system that has already become familiar (say, seven) without reinstalling the OS.
How to install new Windows without deleting the old system that has already become familiar to you? This will be discussed in this article. Having two systems on one PC, every time you turn on your computer, you can choose which system to boot. This approach is very flexible and convenient. You don't have to worry about your loved one file manager or the game does not work in the top ten even in compatibility mode, and it is unknown whether it will run in it in the future. Just download Win Seven and freely use those applications that are not supported by the developers in the new OS, and in the top ten you can work with new programs.
Let's assume that your current operating system is Seven. It is worth noting that the instructions described in this material are suitable for any of the Windows systems, starting with XP (XP, Vista, 7, 8/8.1, 10), that is, you can install any configuration. It is important that the second installed OS is a newer version than the active one. That is, if the computer has seven, you can install 8/8.1 or 10, but not Vista. In case of installation of the second one more early system all information in the MBR record will be deleted, boot files And boot sector, and you will only be able to work with the second, that is, the previous operating system. In this material we will describe the process of installing Windows 10 in conjunction with 7.
Installation procedure instructions
Before the installation process, you need to make sure whether there is an unoccupied logical device (D, E, etc.) on your hard drive. If you installed in system unit two hard drives, you can install the second OS on the additional one HDD, specifying a blank non-system partition during installation as a place to store system files. If you don’t have a second hard drive, we’ll create another, new partition. This can be done using special external applications (AOMEI Partition Assistant, Acronis Disk Director Suite), and standard means. We use the second option - to do this, open the “Run” form by pressing the Win + R key combination, or using the “Start” menu.
Enter the command “diskmgmt.msc” in the text field that appears and click OK.
The Disk Management Manager will open in front of you. Let's create a new partition D. To do this, you first need to shrink the partition with the largest volume, separating the unused partition from it disk space. In our case, this is partition C. For you, it can be any other drive, as long as there is free space on it. Let's click right mouse on the selected device and select the “Compress” option.
In the form that opens, in the “Size of compressed space” field, indicate the amount of disk space that will be needed for new system(for Win 10 minimum – 25-30 GB). After specifying the value, click the “Compress” button.
As a result, on the visual line hard drive An unallocated sector should appear. We'll put a new ten on it.
All these actions can be performed directly during the installation of the second system, but it will be more difficult to do there. So choose which option you like best.
The next step is downloading Windows image 10 from the network and burn it to a DVD or flash drive. Finding an ISO image of the system is not difficult; use a regular Google or Yandex search. You can also download the tens distribution kit from official website. Pay attention to the language and bit depth of the image. As for the first, you will probably need the Russian version. Bit depth is also an important point. You need to focus on the 32 or 64-bit version based on the bit capacity of your processor and the amount of RAM. If you have a 64-bit CPU and more than 4 GB of RAM, you should give preference to the 64x image. If the volume random access memory less, you can get by with the 32x-bit version.
This will help you with recording the distribution to an external drive. Here the recording process is described in detail and in great detail. When downloaded from the manufacturer’s official website, your PC will receive a special proprietary Windows 10 installation program from Microsoft, including all recording tools installation files to the appropriate media.
Further using BIOS settings you need to boot your PC from external storage(laser disk or USB flash drive where you recorded the distribution). How to make these settings is described in the same material.
When everything is ready, insert the media into the computer and boot. If the parameters in the BIOS are set correctly, the message “Press any key to boot from CD or DVD” will appear on the display. Press any button on the keyboard.
After selecting the language, confirming the license and specifying the installation type, we proceed to the hard disk partitioning form.
If you have done all the partitioning work in advance, and you have 25-30 GB of unallocated space, select the unallocated area to install the second system and click “Next”.
If free space is not enough, you will have to delete one of the occupied partitions, which will expand the unallocated disk space. It is important to understand that when you delete a partition, all data on it is destroyed. That is why we advise you to do all the partitioning in advance, in the disk management manager on the current system, since there partitions can be compressed rather than completely deleted, which will prevent data loss.
So, the main installation phase begins. It will take some time, so be patient.
All subsequent installation stages are described in the same material, and we will not dwell on them.
Finally, when Windows installation 10 on a laptop, computer or tablet is completely finished, the device reboots, and the next time you turn it on, it appears on the display boot menu with the choice of system to launch. Having selected the desired item, you can use any of the versions (see the picture on the main page).
Provides interesting opportunities additional option“Change defaults or choose different options” located at the bottom. When you click on it, a subform appears. Here you can set a timer to display the system selection menu, after which the default OS will be loaded. You can also specify Windows version For automatic download, which will occur if there is no action on your part during the interval specified above.
Click on the third item “Select other options”. In this menu, the most interesting option is the “Diagnostics” option.
The first option is “Return the computer to the initial state"is useful if the integrity of the system has been compromised (that is, you cannot manually remove applications, install new ones, loading does not occur, etc.). As a result of such a rollback, you can perform reinstalling Windows, removing non-factory applications and settings while preserving personal data and documents. A similar operation can be carried out through the GUI in the top ten itself.
Now about the last subform " Extra options"What features does it provide?
The first option allows you to restore the system using the restore point mechanism. Such checkpoints are created automatically during the installation of some programs, and are also generated manually by the user before making major changes to the OS. The next menu item “System Image Restore” will be useful when returning Windows status to the initial one using an ISO image of the distribution saved on the hard drive (very useful in the absence of boot disk from Windows).
Another useful item is “Startup Recovery”. If the system does not boot, it will help fix system entries and return the ability to boot. Command line – indispensable tool For system administrators, For ordinary users he is of little interest.
The fifth option "Boot Options" is used to debug Windows in safe mode. The last option “Return to the previous build” will come in handy if bugs, frequent freezes or lags occur as a result of updating the OS. This is possible if the new build has not been sufficiently tested and was released in a raw form. After rolling back to an earlier build, the settings and applications installed in the new branch will be deleted, but personal files will not be affected.
Using the described instructions, you can completely cope with the question of how to install a new Windows in parallel with 1 or 2 other systems on one hard drive, provided there is sufficient space.
Sooner or later every user mobile devices from Apple is faced with the idea that it might be worth returning to the old version of iOS.

Sometimes you need to install an older version of a package/program due to stability or other reasons. Let's figure out how to do this.
APT always installs the latest version of the package available. And if you have problems working with new programs installed from a third-party repository, then in such cases the utility can help, which will roll back all versions of packages from the third-party repository to the native ones from the official repository.
But it happens when you need to install a package or program from a third-party repository with a lower version than in the native repository, or you have connected a repository in which there are several programs, but you only want to roll back a specific program. How to be?
Consider the option of downgrading the version of Gimp.
Version installed 2.9.1.83
from a third party repository, but I want to install the version 2.8.6.0
, and in the native repository only the version 2.8.6.1
, which, for example, also doesn’t work well or doesn’t suit me, etc.
First, let's find and connect the repository with the required version of the program, and also make sure that the version of the program is available for your OS. To do this, go to the Launchpad.net service and look for available versions of the program.
Connect the repository:
sudo add-apt-repository ppa:noobslab/ppa-gimp
sudo apt-get update
Now let's look at the list available versions programs:
apt-cache policy gimp
Yeah, the required version is present, so we move on.
Let's remove the package whose version we want to downgrade so that we don't have to deal with dependencies and other problems in the future. We also remove dependencies:
sudo apt-get purge gimp
sudo apt-get autoremove
The packages have been removed, let's proceed with installing the required version of the program:
sudo apt-get install gimp=2.8.6~saucy~NoobsLab.com
And here are the pitfalls! I didn't specify versions for dependency packages libgimp2.0 And gimp-data. As I wrote above, APT always installs more recent versions of packages, so that’s why it happened.
We manually specify these packages:
sudo apt-get install libgimp2.0=2.8.6~saucy~NoobsLab.com gimp-data=2.8.6~saucy~NoobsLab.com
