(humm... my keyboard is broken, so I can't type chinese, sry.)
my original computer(another one, I have 2) system is win7 ultimate. And I used win10(home) usb boot to make 2 systems. Unfortunatly, I format D:/ carelessly. Despite of cancelling the win10(home) usb installation ASAP, I can't boot my computer.
What should I do next?
