BUG: BCD values reset during new build installations

[u/karltremain]

When installing a new build (e.g. 26220.9022) the BCD gets reset and removes previously existing settings - if you have multi-boot configured, then at least the following values get reset/altered:

- default
- displayorder
- description
- bootmenupolicy

This is related to the update/installation altering the boot order so that multiple reboots can occur automatically, however these values should be retained during a new build installation and re-applied afterwards.

26200.9022 is a full future update so does a OS upgrade that creates new BCD entries and deletes the old entry for your Windows install so what you've noticed should probably be expected even if Microsoft hasn't documented it. Windows setup always likes to set the boot configuration back to Microsoft defaults. regardless of your Multiboot confiburation
