Restore Lost Files While Upgrading to Windows 10 using USB

“I didn’t have licensed version of Windows OS on my desktop to get free upgrade of Windows 10. So, I got the setup file from my friend and tried to upgrade the OS by running the file from USB pen drive. The process took couple of hours and didn’t complete. After waiting for another one hour I hastily clicked for cancel button which reverted back to previous OS. But later I noticed that some files and folders were missing from the drive. I don’t know what should be done now as I am unable to track all my important files on system. Can anyone suggest me how to recover files lost while upgrading to Windows 10 using USB drive?”

Losing files during Windows 10 upgrade is commonly seen nowadays among many users who don’t have licensed Windows OS versions. Yes, if the computer is not running with genuine version of Windows OS then such users cannot freely upgrade it to Windows 10. In such case, one has to get Windows 10 setup file from other genuine OS users who got free download of that file. Then run this file from USB by connecting it to the system. Unfortunately, while upgrading to Windows 10 using USB, unexpected things may happen causing severe data loss from computer drive. Here are some of such cases:

  • Abrupt removal of USB drive in the midst of upgrade process can cause OS crash and hence data might become inaccessible
  • While upgrading to Windows 10 using USB, user will be popped up with only one option i.e. complete format. If he/she has backed up all important data onto D drive thinking that upgrade process will only formats C drive then all these data will be in vain as the process formats complete hard drive
  • If you try to upgrade OS to Windows 10 using USB drive, it asks to create an install media. If any interruption or error occur at this stage then process of OS upgrade may revert back to previous OS thus causing data loss or hard drive crash

Not to worry much if critical data is lost from computer while upgrading to Windows 10 from USB device. All those data can be retrieved by employing good data recovery program if user saves no new data onto the system hard drive.
