An UEFI Secure BOOT system (MBR-based disk) has gone belly up. All required partitions (EFI, MSRP, etc) except the Windows partition (original C: ) have been destroyed (cannot be reconstructed). Goal... I would like to use the existing Wndows partition (C: from above), if possible, in a LEGACY/MBR configuration rather than UEFI (both are available). What's the easiest way to get from where I am to my goal, if even possible? It's easy to ACTIVATE that existing partition but I know the required BOOT files are not on it. Any creative suggestions? (I don't have BIBM but can probably get it, if necessary... any other method probably better due to limited knowledge of BIBM).
