Windows operating systems for all time of its existence have come a long way of development.They have improved every year, and this was released the latest version of Windows 8 is hovering right at the first presentation of Microsoft, and then recognized by the developers failed.Then the user is faced with a very serious problem.On the one hand, all the latest models of computers and laptops are available with "eight".However, modern hard disks used in them are markup gpt.As a result, an error occurs when you install Windows 7. What might be the reasons?Why laptop gives out the message "Installing Windows on the disc can not"?GPT-section blame.
"old" or a reliable friend?
Until the creation of Windows 8 operating system used by hard disk markings called mbr.Accordingly, the support sections are carried out exclusively in the latest version.Thus, if you are going to demolish the established "eight" and put an older version of the operating system, they will not be able to recognize the new interface GPT, with the result that during installation, you may receive the inscription "Installing Windows on this disc is impossible."GPT will not be recognized, so that the user can not even determine what the problem is.Let's see its essence.
older operating systems work with the MBR.What it is?MBR (Master Boot Record) - This code and information necessary for the pre-launch of the system.They are located in the first sector of a hard disk markup.Starting the MBR passes after the initial inspection bios of all devices.Its main feature - the definition of the files necessary to boot the operating system.As you can imagine, the error when installing Windows 7 can be caused by the fact that the new standard EFI, using GPT, is unable to determine the operating system and write it in your startup partition.
What is GPT?
GPT - accommodation standard format of the partition table on the hard disk.The fact that Intel has introduced a new interface to replace all the usual BIOS.He called EFI (extensible firmware interface), and is part of a new format - GPT.
One of the features of the standard EFI is that it has two possible ways of the initial load.Because GPT uses logical block addressing system, the starting blocks and have the following structure:
- LBA 0 - the very first sector containing information MBR.So the creators of the insured themselves to be able always to convert the disk under the required format.
- LBA 1 - there is a table of contents of the partition table format GPT.
- LBA 2 - this sector is intended for storage of the partition table.
Proceeding from the above, you need to understand that these two standards partitioning so different that new hard drives installation of Windows can not.GPT will not allow the operating system using mbr, take and erase the hard drive partitions and thus may damage the structure.
Ready!
So, if you still decided to reinstall the operating system, be sure to prepare everything necessary:
- Back up your data.It is desirable to external media to prevent loss.
- Make sure you have the installation disk of the operating system, it is OK, and with it you can actually hold a reinstallation.It does not matter whether or not he is a pirate.
- Be prepared for the fact that your actions can cause irreparable damage to your computer or laptop.Make sure there are not any problems with your particular model PC.For example, a company of HP notebooks very well protected from being overwritten, and even experienced programmers have difficulty resetting the system to them.If you remove the laptop from such a system, most likely you will not even get his own back the old.
you ready?Then we begin.
Reinstalling
first series of steps that must be followed when installing the operating system:
- restarts the computer.At this point the clamp key F2, to get into the BIOS management.Remember that the buttons you need to run this subroutine may be different for different models of laptops, but for a very short period of time in which you need to have time to press the button, it's better to just hold on all the time restart.
- Once in the BIOS, you can complete the last stage of preparation for reinstalling - insert the installation disc into your computer.
- In setting specifies the device from which you want to boot the notebook.You need to set the first line of your drive.
- In additional options, security settings, instead of the standard set UEFI option "Legacy" or "Legacy and UEFI".This will remove protection from the reinstallation.
- Save and exit the BIOS.Then restart your computer.
- When the inscription "To boot from the disc, press any key ..." comply with a request of the computer.
- appears the start screen of the operating system installer.Go through the dialog boxes, reach the Manager managing hard disks.Remove all existing partitions (except the first).Formatting the hard drive.We try to point it to install the OS.
- It is at this stage, the system can warn you that the installation of Windows on the disc is not possible.GPT format will not let you perform the installation of the system.
- If you did not have any difficulties or labels, quietly continue the installation according to this manual.If you can not complete the installation, see the next section of this article.
- So eliminating all obstacles proceeding.It may take you up to two hours of free time, so leave your computer, you can safely go to drink tea.
- final stage will be initial setup PC.Set date format, time and language.Enter the activation key.Your operating system is ready for operation.
Convert
If you encounter a problem when selecting the hard drive to install, and you received a message that the installation of Windows on the disc is impossible, gpt format you need to convert to mbr.For this will have to do the following.Press "Shift + F10".Then enter several commands in sequence:
diskpart - sel dis 0 - clean - convert mbr - exit - exit.
This will allow you to convert the format of sections mbr.Now you can safely continue the installation of the operating system according to the previous chapter.
exception
So, after reading, you can manually begin to reinstall your operating system.Despite what has been said in this article, the installation of Windows on the gpt (section no "magic") is possible in two cases.First, if you put an operating system or an assembly support GPT partitions.Secondly, in the case where the operating system installation "under" Windows 8 independently capable of converting the hard disk partitions in the desired format.In other cases, installation is not possible, gpt nothing to do with.The creators of the original laptop can make sure that users do not reinstall the operating system and not to produce pirated copies.
