recently I installed Windows 10 pro from my main hard drive(1TB) to the secondary one (500GB) with Easy BCD and now I need to delete the C drive from the main drive(1TB) but it is still showing its SYSTEM volume in the disk management, hence i cannot delete this volume but OS is being Booted from (500GB) drive im confused..

Actually, I solved the issue with EasyBCD by rebuilding the boot files.
Thanks for reaching.
