Wanted to examine boot.ini, but there is no boot.ini on the server.
Tried to recover this with Windows on-board utilities, but no success.
Finally booted system into Recovery Console and recreated it there with bootcfg /rebuild.
After reboot, tried conversion again.
It failed at 51%.
Error message:
FAILED: An error occurred during the conversion: 'BlockLevelVolumeMgr::CloneVolume:Detected a write error during the cloning of volume \\WindowsBitMapDriverVoumeId. Error: 37409 (type: 1, code:2338)' 
This refers to a problem with source disks.
Run chkdsk on all disks and repair any problems.
This solved the problem.
Conversion finally worked.


  1. Recreated boot.ini on source machine.
  2. Repaired failures on source disks with chkdsk.
