OS/2 Make drive bootable

I accidently booted an OS/2 system with a Windows 95 OEM preinstall boot floppy, which copied the Windows 95 system files to the root directory of drive C. It boots to a 2 item menu, one starts OS/2 on drive D, the other is supposed to start OS/2 ondrive C (each with different configurations). I can boot to drive D, or from floppies. How do I transfer the system files to drive C to make it bootable again?
