WORKED SOLUTION: I had also the same error blinking letter "J" with the tool MiniTool Partition Wizard. What helped was performing an extra step in MiniToolPartition Wizard. Click on new SSD Disk, went to menu "Disk" --> "Rebuild MBR" (on new disk) --> Apply. Afther that new SSD disk was recognized when booting to Windows 10.
