Try to rebuild bcd.
So i unplugged my old HDD and that caused every drive to change letter (dont know why) my other SSD isnt showing up and i tried every method. I dont have a bcd file in my boot folder. I dont have a bootmgr file in my Boot Drive and now i get another option saying use another operating system on the troubleshooting page. When i click it i get two windows 10 options up all on volume 6 and as you can see i dont even have volume 6 are they invisible or something. Dont get why it was fine a few days ago but now i cant even boot the pc when the HDD is plugged out (like it was a few days ago).
