  12. Adopting the terms of the license agreement in the Windows 7 installation window

  13. In the next window of two proposed action options, choose "Full setting" .
  14. Selecting an installation type in the Windows 7 installation window

  15. Next will open the shell, where you want to highlight the HDD partition from the OS that you want to delete. Opposite the name of this volume must stand the parameter "System" In column "A type" . Click on the inscription "Disc Setup" .

Windows 7 removal tips

If there is no experience or do not know how to remove Windows 7 correctly, we recommend that you listen to the advice, which give experienced professionals in this matter:

  • No need to rush, save important information. We recommend to prepare for 2-3 days and start to transfer everything to one external media to the removal process. This will help structure your files, do not send the needed to the basket, do not transfer unnecessary or not necessary.
  • Newbies are better to refuse to remove Windows OS 7, if there is no other operating system on your computer. You will not access the usual graphic window with prompts - settings should be carried out only via BIOS.
  • Removing such folders as "Program Files" Windows does not mean that the OS cleaning has been performed correctly and has successful results. In some folders and files, which can be seen, in any OS there are a fairly huge number of different configuration settings that are "attributed" to Hard disk. They remain hidden for a user eye. Full-featured cleansing from Windows 7 requires total cleaning (formatting) of the disc itself.
