Steps to reproduce: 1) Insert portable USB drive. 2) Create BCD partition and load its BCD store. 3) Edit boot menu (added 1 ISO boot entry in my case.) 4) Go to Windows Explorer and eject drive. 5) Try to exit EasyBCD (using all possible methods: Alt+F4, clicking the red X in the window menu, going to File -> Exit) Expected Result: EasyBCD exits. Actual Result: EasyBCD pops up dialog indicating "Cannot find BCD Store at <Drive Letter>:\boot\bcd". WHen you click OK, EasyBCD remains open. Additional Information: Finally killed the process via Task Manager, which raised a "Not Responding" message from EasyBCD forcing a hard kill of the process.
