If you run into issues on your Windows 10 whatever issues they are, regardless of the issue Windows 10 allows you to do a repair install without booting directly from the installation media. Repair install will repair system files, and install the latest windows updates. The process is quiet straight forward and easy. However, before you begin, you will need to ensure that the following requirements are met.
Ensure that you have at least 9 GB free space on your hard disk (Windows Drive).
Have the installation media ready. You may do this using the USB or ISO file. However these MUST be the same build and edition as the Windows 10 software that is currently installed. Otherwise the repair install will not be successful.
The installation media MUST also be in the same language as the Windows 10 already installed. This is important especially for keeping files after the repair.
Use 32 bit or 64 bit for corresponding Windows 10 installations.
Repair install of Windows 10
There are three methods that you can chose to begin the repair install.
Create a Windows 10 Installation Media
Option 1: Windows Repair Install Using the ISO file
NOTE: This method should ONLY be used if your Windows 10 was activated.
Download the Windows 10 ISO file from here.
Save it on your PC, preferably on your desktop at first.
Now mount the ISO file click (here) to view steps.
Now double click on the file setup.exe to kick start the repair – install from the mounted drive.
Option 2: Windows Repair using USB Installation Media
This option can be carried out by using the Windows Media Creation tool. Ensure you have suitable internet connectivity; and also prepare an empty USB flash disk with a minimum of 4 GB for a 32 bit installation or 8GB for 64 bit installation. If you use a flash drive with data inside you may lose it in the process. Now read system requirements, and keep the Windows 10 product key near you (if Windows 10 was already activated before you may not need it).
Once the download has completed, right click on it and select Run.
If prompted by UAC, click ‘yes’.
On the panel that appears, select the second option that reads “Create installation media for another PC” and then click NEXT.
The next panel is for language, architecture, and edition. Right under Architecture, uncheck the box for “use the recommended options for this PC”. This bit is important because it will allow you to specify the language, edition, and architecture as the current Windows installation.
In the boxes provided, choose the Language, edition and architecture. You can have both 32 bit and 64 bit Windows installations on the same USB, or simply opt for the one you need. Failure to provide a product key if prompted will allow you to only proceed with Home and Pro Keep in mind the version that was initially in your PC. Click Next.
The next panel offers two destination options for installing Windows 10; the USB or ISO file. Select the ‘USB flash drive’ option and proceed.
Plug the USB disk (either 4GB or 8GB depending on your preferred architecture) and then click on the instruction ‘Refresh drive list’. Your plugged USB will appear beneath. Select it and click NEXT.
Windows 10 now takes over and the download begins. When the download completes your USB is now fully set. Click FINISH.
