Installing Windows OS without CD/DVD or USB flash drive


Hello. In this article we will learn how to install Windows OS without to have a CD/DVD or USB flash drive or network shared. You know that sometimes happen that something goes wrong with our hardware components like CD/DVD or USB ports don`t work or we have only a netbook which have just USB ports, anyway something goes wrong with our PC and we aren`t able to install or reinstall Windows OS. But we need something to start, something at the base, because we can install Windows without nothing, that`s impossible. So for this we need a ISO image with the OS (You know where to find it, that`s your job).

The first step we have to do is to make another partition on our hard disk around 5 GB where we will put the Windows files.

But before making another partition we have to follow some rules for that. The hard disk contains files and temporary files which are spread all over and we need to compress and arrange them because if we create another partition we will take from the primary partition where is the OS with its files we will get an error and we will damage the system and we will not be able to get in it. That`s way is recommended to backup your system.

We need to download a software to clean the PC (temporary files, empty Recycle Bin, clipboard, memory dumps etc) (I will make an article about this software) the software named CCleaner and choose the free version. Run it and follow the wizard to install it and then open it. Installing Windows...

and click on Installing Windows... to clean the PC.

Then we have to compress the files and we will use Disk Defragmenter from Windows. So click on Start button Button and in the Search box write defrag... and choose Installing Windows... .


Installing Windows...

In the windows menu click on hard disk partition and then click on Installing Windows... and wait till defragmentation is complete.

The next step is to download another tool to create a new partition where we will put the Windows files. The tool is MiniTool Partition Wizard and is one of the best (I will present the tool in other article). After downloaded, install it following the wizard and then open it Installing Windows.... Click on the partition you want to resize and then right click to open the menu and select Installing Windows...

In the Move/Resize Partition wizard change the size of the selected partition Installing Windows... and to get 5 GB on the other partition Installing Windows.... In others words we take from one to create another one and after click OK. After we have to create a new partition from unallocated space, so right click on Unallocated and then click on Installing Windows...


Installing Windows...

Now we will change the name of the new partition, will create partition as Primary and the files system as NTFS because the Windows OS can be install only in NTFS format. Installing Windows... Now if you have 4 primary partitions on your computer you can`t create one as the PC can support only 4 primary partitions and we need to change one of them in logical but not the partition with the system installed.


Installing Windows...

and click OK.


Installing Windows...

After we verified all the changes click on Installing Windows... and in the next windows click on Installing Windows... to take effect our changes.


Installing Windows...

After restarting you`ll see that the our changes will take effect from boot mode, then the computer will restart automatically.

So far so good, we created the new partition. As I wrote above we need a ISO image with the OS, right click on it and select Installing Windows... . You can open the archive with 7ZIP, WinRAR or with Windows Explorer etc.


Installing Windows...

Select all the files (CTRL+A) and copy them Installing Windows... in the new partition created.

At this moment we need a tool that can write in Boot Manager the new files with Windows OS. The EasyBCD is the perfect tool for this task (I will write an article about it). After downloaded open it. In the menu select Installing Windows....

Here click on Installing Windows... and then write the name of the entry in Boot Manager Installing Windows... and after select Installing Windows.... The Boot Manager needs some files to load them, that`s why it needs a path to files ( the file is "boot.wim") and search for the file Installing Windows... and select it Installing Windows... and then click Open.

After finishing just click on installing Windows... and the new entry is added to Boot Manager. Now we can restart the computer and in Windows Boot Manager select the second option Windows 7 Reinstall with arrows key from keyboard and press Enter

So we are booting now the Windows OS from the new partition created before. All we have to do now is to follow the wizard.


Installing Windows...

Click now on Installing Windows... and then accept the license terms just fill the box and click Next


Installing Windows...

and choose Installing Windows.. and be careful what you select (don`t select the partition with Windows 7 Reinstall), choose the first partition which you want to install or reinstall the OS.
