I was using my laptop and when i upgraded to windows 10, I decided after it upgraded, to have some fun time on it.Then after awhile I would reset it. But then when it finished, I got INACCESSIBLE_BOOT_DEVICE, i tried everything. i tried booting my computer with a Usb Flash Drive thats empty and over 3 GBs, with Windows 10 Install, i tried using repair my computer. But nothing Worked. I went from Windows 7 to 10 by the way. Can somebody please help me! I even looked up other videos and forums, but nothing worked.
