Exporting and Importing Boot Entries in EFI
Use the nvrboot x (export) command to create a backup copy of a boot entry. Design a naming and storage convention that will make it easy to find the backup copy files when you need them.
Use the nvrboot i (import) command to import boot entries from the backup copies that you exported or from the Bootxxxx boot entry backup files that Setup created.
Imported boot entries always receive new EFI boot entry IDs. For example, if you export a copy of Boot0003, and then import the copy into NVRAM, the imported boot entry receives a new boot entry ID, such as Boot000A.
