Q. How do I mark an OS loader as a Windows Recovery Environment (RE)?

A. There is a custom attribute, 460000010, in the Windows boot configuration database (BCD) schema that sets an OS loader as a Windows RE for other OS loaders. Use the following command to create the entry, but note that you should set it only on a Windows PE/RE environment:

bcdedit /set \{57f9d851-b1b2-11dc-9cfd-e2c2d840594d\} custom:46000010 yes

Once that is set, you can set other OS loaders to use the configured OS as the Windows RE.
