Removed all other HDD from PC. Loaded from installation media (flash). used 'diskpart' to reassign drive letters properly 'BootRec' /fixmbr , /fixboot , /ScanOs , /RebuildBcd and it did the job |
|
|
Another option - Paragon USB boot, P2P |
|
|
for error "BOOTMGR is missing" need to start from windows installation media and run in cmd: copy "D:\bootmgr" C:\ this is how Windows 7 can be started from the only one volume left on disk this volume partition must be set to active |

try with Windows 10 bcdboot C:\Windows /s D: /f ALL and it become bootable |
