Some of the commands were typed using D: instead of X:
And one of the commands had a typo.

This command was posted in the D: and was typed as bc dedit | "osdevice"
(there is no space between bc edit)
| "osdevice" should be | find "osdevice"

Can you post images of this command using X:
type: bcdedit | find "osdevice"

See if you can use Kyhi boot rescue:
