Thirdly: How to create a bootable USB of windows image that can be used to repair or to install windows or another OS:
3.a.1. Download the ISO Image of windows 10 from the official Microsoft website:
3.a.2. Download the EmptyImage.ISO file
The links are available in description below
3.a.3. Connect the USB drive to your mobile and Flash the empty ISO image, which will create an empty bootable USB.
This step is important because USB with FAT32 cannot accept files larger than 4 Gigabytes.
Also, the ISO 2 USB app does not support NTFS file system that can accept files of any size.
So, if you have an OS with an ISO file smaller than 4 Gigabytes, you can flash it directly without flashing that blank image.
3.a.4. Open the RAR app and navigate to Download folder
3.5. Select Windows 10 ISO file and extract it to any folder
3.a.6. Open extracted folder of windows and navigate to sources folder
3.a.7. Select Install.wim file
3.a.8. Press on this icon to create a new archive
3.a.9. Move to advanced tab
3.a.10. Change volume size to gigabyte
3.a.11. Type 2 into text box
3.a.12. Press Ok to start compression.
This step will split the install file or Windows image into multiple parts of 2GB each
instead of the current size which cannot be transferred to USB with fat32 file system,
because it is larger than 4GB in size.
3.a.13. Delete Install.wim file from extracted folder.
3.a.14. Open any file explorer and navigate to extracted folder.
3.a.15. Select all files and folders then press on Copy option
3.a.16. Go to USB drive and paste the copied files and folders
3.a.17. Check Apply to all option then click Overwrite icon to replace everything
3.b.1. Now, connect the USB drive into your computer and boot from it.
3.b.2. Change keyboard language then click on Next
3.b.3. Press on Shift+F10 keys from keyboard to open Command prompt.
3.b.4. If the Shift+F10 not working, Click on Repair your computer option then open CMD from Advanced Recovery
3.b.5. Type Notepad and hit Enter
3.b.6. Click on File tab and select, Open option
3.b.7. Click on This PC icon
3.b.8. Open USB drive
3.b.9. Open 7-zip folder
3.b.10. Change Files of type to all
3.b.11. Right-click on 7z Fm file and select Run as administrator option
3.b.12. Navigate to USB and open sources folder
3.b.13. Select Install.part1.rar and click on Extract icon
3.b.14. Change extraction path to C partition or any partition with enough free space.
3.b.15. Uncheck this option.
3.b.16. Click Ok to start extraction.
You will not be able to extract to USB directly, because the extracted file will be larger than 4 gigabytes.
This file is very large, because it contains 11 folders, and each folder contains different windows edition.
So, to reduce its size, you have to extract only one edition that you are planning to install in your computer.
3.b.16.1. To see type of these editions, do the followings:
3.b.16.2. Execute this command to change CMD path to system32 folder: CD /D C:\WINDOWS\SYSTEM32
3.b.16.3. Execute this command to view indexes details: DISM /GET-WIMINFO /WIMFILE:C:\INSTALL.WIM
As you can see, the folder or index number 1 contains windows 10 home,
index number 2 contains windows 10 home N,
index number 4 contains windows 10 Education
and index number 6 contains windows 10 Professional.
3.b.17. Back to CMD
3.b.18. Execute the following command to extract index number 6 from install.wim image, which contains windows 10 pro: Dism /Export-Image /SourceImageFile:C:\install.wim /SourceIndex:6 /DestinationImageFile:E:\Install.wim
Replace the E with the letter of USB partition.
If you need another edition of windows 10, replace the 6 with the corresponding number from previous list of indexes.
3.b.19. Close CMD and Notepad to go back to installation menu.
Now, the USB is ready to install windows from it.
3.b.20. To install windows, click on Install icon and follow the instructions from your screen.
