Your story seems to happen a good bit. The best way to deal with this kind of thing is to back up your entire system before making the upgrade to 10. Short of that, you'll need to backup your data and reset to factory settings.

Good luck.
I downloaded windows 10 from Microsoft windows website and I installed it but I thought of reverting back to windows 7 and so I did. The windows 7 boot up logo showed up but got stuck in between the boot logo. then the windows startup fixing program would be recommended for me and I did it but failed to fix the boot up error. and i cant even start windows from the safe mode as well. So what do i do to bring back windows 7 back up. and which one windows is good 7 or 8 or 8.1 and sure that i wouldn't wanna go back to 10. so how do i start up windows again?? Yeah i guess i will have to make a bootable USB or DVD drive. I would like to go for usb but not sure how to create one bootable usb drive. so can anybody help me out to create it? Any help would be accepted thanks a lot
