In Windows Recovery Environment (WinRE), you can use the diskpart command to list and manage disk partitions, which can help identify Windows installations not included in the Boot Configuration Data (BCD). After identifying the partitions, you can use the bcdedit command to view the current BCD entries or the bcdboot command to add new entries for detected installations. Additionally, the bootrec /scanos command can be used to scan for Windows installations not listed in the BCD.
