I am fixing/formatting my flash drive using command prompt but I didn't notice that I chose my disk. Now it prompted something saying it failed becausw of booting something I can't remember. So I open uo file managee and can't find my D: drive. Also my game crashed, I tried running my game again which is installed on my D: drive so I thought it can resolve by restarting my pc but now I can't boot my pc. It only shows Missing operating system. Can you guys helo me, what can I do? Please I need your help ASAP
