Pen Drive format and detection problem

when i plug in the pen drive it shows that you need to format it before using. When i try to format then it shows that windows was unable to format. I've tried the disk management method, drive management method and the cmd method but was not unable
to format it because the detection of pen drive is for just a few seconds and then it disapears. I have also tried to uninstall the drivers within those few seconds and then pug in again but the same message appears.I have windows 10. Please help me!

 

Your E: drive contains the Bootmgr and marked as active. You cannot format it until you move the bootmgr back to C:. Use Easy BCD to move it.
