Ok so i am having bootmgr is missing error on windows 10.I tried using my bootable usb and booted and then clicked repair option.Then i used cmd after that i typed diskpart command but it only shows one drive and that is usb drive itself.No other drive shows.But my bios is detecting harddrive.I also removed harddrive once and then again installed it.But still this issue persists and seems like windows is not detecting my harddrive.Plz help also a day before i was playing with disk managment options bcz i wanted to extend my c drive so i shrink volume on e but it didnt work so restored volume after that i turned on my pc after few hours then this error startes showing
